Junk Perry Plant Vessel Level Control.

The MFP trips and they get a scram. water level declines to the low level scram setpoint. The RFP, HPIC and RCIC starts up and feeds the vessel. Vessel increases so fast it goes to the high level trip. The RFP, HPIC and RCIC trip. This is not control of vessel level. This happened in all these LERs. This is call banging around vessel level.
 
These systems aren't tuned for each other. You are not suppose to get to a low level trip then the high level trip. All these guys got control functions aiming to get level in the mid level or slightly higher. Why doesn't it work as designed?
 
This unprofessional vessel control is distracting the operators from the big picture.

"Loss of Feedwater Results in Automatic Reactor Protection System Actuation".


On November 7, 2014, at 0847 hours, the reactor protection system (RPS) automatically actuated due to a loss of feedwater flow to the reactor pressure vessel (RPV). There were no complications during the shutdown as all control rods fully inserted and pressure was maintained by normal means. The high pressure core spray (HPCS) and the reactor core isolation cooling (RCIC) systems actuated based on a valid low reactor water level initiation and injected to restore RPV water level. 

RPV water level continued to decrease to the Level 2 setpoint (130 inches above TAF) when the RCIC and HPCS systems started and injected into the RPV. Balance of plant isolation occurred with isolation of all required valves. Both reactor recirculation [AD] pumps tripped as designed. The division 3 EDG, which supplies emergency electrical power to the HPCS system started but, as designed, did not load onto the bus. The MFP started as designed on a RFP trip signal. At approximately 0850 hours, the HPCS and RCIC system injections terminated on a Level 8 setpoint (219 inches above the TAF) as designed. The lowest RPV water level reached during the event was 77.2 inches above the TAF. RPS was reset at 0915 hours. Mode 4, Cold Shutdown was entered at 1752 hours. 

CAUSE OF EVENT 

The RPS scram was caused by an invalid feedwater runback signal from the division 1 RRCS. A recorder was installed for additional monitoring purposes and identified signals being injected from the RRCS self-test system (STS) feature into the DFWCS. Data analysis determined that the voltage perturbations correlated to the STS within RRCS. The voltage perturbations had amplitudes of - 66 VDC with pulse durations of - 1 msec. These pulses would repeat in a repetitive pattern between 5 to 7 pulses with noted frequencies varying as short as 130 - 230 msecs. The patterns would occur for a period of - 10 seconds on 2 minute intervals. This signal has a large enough amplitude for actuating the input on the field bus module (FBM); however, the DFWCS software has a 1 scan (200 msec) delay feature to prevent the actuation. A DFWCS runback signal can occur when a signal is in for greater than 200 msecs or these 1 msec pulses align exactly at 200 msec apart. The root cause was determined to be a latent design flaw in the upgrade design package of the DFWCS modification in 2005. Due to implementing the new digital upgrade, the interface between RRCS and DFWCS involving the runback signal was altered. The original design used interposing relays as the interface between the RRCS and the feedwater control system. The digital upgrade changed the design interface and removed the interposing relays tying the output of RRCS directly into DFWCS.

"Loss of Feedwater Results in Automatic Reactor Protection System Actuation".
 

On October 20, 2014, at 0217 hours, the reactor protection system (RPS) automatically actuated due to a loss of feedwater flow to the reactor pressure vessel (RPV). There were no complications during the shutdown as all. control rods fully inserted and pressure was maintained by normal means. The High Pressure Core Spray (HPCS) and the Reactor Core Isolation Cooling (RCIC) systems actuated based on a valid low reactor water level initiation and injected to restore RPV water level. 

RPV water level continued to decrease to the Level 2 setpoint (130 inches above TAF) where the RCIC and HPCS systems started and injected into the RPV. Containment isolation occurred with isolation of all required valves. Both Reactor Recirculation [AD] pumps tripped as designed. The Division 3 EDG, which supplies emergency electrical power to the HPCS system started but, as designed, did not load onto the bus. At approximately 0221 hours, the HPCS and RCIC systems and the MFP stopped injecting when the Level 8 setpoint (219 inches above the TAF) was reached. The lowest RPV water level reached during the event was 87.1 inches above the TAF. RPS was reset at 0240 hours. Mode 4, Cold Shutdown was entered at 2323 hours, when the average reactor coolant temperature decreased to 200 degrees Fahrenheit. 

CAUSE OF EVENT 

The RPS scram was caused by an electrical transient in the balance-of-plant (BOP) 120 volt AC Uninterruptable Power Supply (UPS) system [EJ]. At the time of the event plant operators were in the process of shifting the BOP static transfer switch [ASU] to its alternate source for maintenance on the BOP Inverter. The transient was caused by a degraded static transfer switch component. Alternate supply voltage was available but a static transfer failure resulted in a loss of power to the UPS system loads. During the subsequent investigation, it was found that the static transfer switch's alternate power silicon controlled rectifiers (SCRs), were not firing due to an issue from the sensing and transfer card [ECBD]. Without the alternate SCRs firing, no voltage would be provided from the alternate source. Laboratory analysis determined that the card had a degraded logic chip. A NAND gate used in the logic chip was degraded. The degraded NAND gate caused a voltage drop resulting in 6.5V at the input to the downstream logic. This was lower than the expected 15V and failed to generate an "on" signal to the downstream logic. This prevented a firing signal being sent to the alternate source's SCRs. Analysis determined the degradation to be the result of a manufacturing defect. The control logic for the DFWCS is one of the electrical loads serviced by the UPS. Among the loads was an input signal to the RFP availability logic. Disruption of the DFWCS power due to the electrical transient affected the feedwater system causing the control circuit to believe it was not available and drove the output to zero. As a result, feedwater flow was lost to the RPV and the RPS actuated, as designed, when RPV Level 3 was reached.

"Loss of Feedwater Results in Automatic Reactor Protection System Actuation."


On January 22, 2013, at 0332 hours, the reactor protection system (RPS) automatically actuated due to a loss of feedwater flow to the reactor pressure vessel (RPV). There were no complications during the shutdown as all control rods fully inserted and pressure was maintained by normal means. The High Pressure Core Spray (HPCS) and the Reactor Core Isolation Cooling (RCIC) systems actuated based on a valid reactor water level initiation and injected to restore RPV water level. 

The cause of the event was failure of a balance-of-plant inverter/static transfer switch, which provides electrical power to the digital feedwater control system. A circuit card in the static transfer switch degraded, which affected operation of the inverter. The electrical loads serviced by the inverter/static transfer switch were placed on an alternate power source. This alignment will continue until permanent repairs are made which are currently scheduled for the next refueling outage. 

RPV water level continued to decrease and when it reached the Level 2 setpoint (i.e., 130 inches above the TAF), the RCIC and HPCS systems started and injected into the RPV. Both RFPs and the main turbine tripped. Containment isolation occurred with isolation of all required valves. Both Reactor Recirculation [AD] pumps tripped as designed. The Division 3 EDG, which supplies emergency electrical power to the HPCS system started, but did not load onto the bus, as designed. The MFP started as designed when the RFPs tripped. At approximately 0335 hours, the HPCS and RCIC systems and the MFP stopped injecting when the Level 8 setpoint (i.e., 219 inches above the TAF) was reached. The lowest RPV water level reached during the event was 79.8 inches above the TAF. RPS was reset at 0413 hours. Mode 4, Cold Shutdown was entered at 2036 hours when the average reactor coolant temperature decreased to less than 200 degrees Fahrenheit. 

CAUSE OF EVENT 

The RPS scram was caused by an electrical transient in the balance-of-plant (BOP) 120 volt AC Uninterruptable Power Supply (UPS) system [EJ]. The transient was caused by a degraded static transfer switch component [ASU] coincident with a failed DC to AC inverter [INVT]. The static transfer switch did not seamlessly transfer the loads to the alternate source. The inverter was found on the alternate source with the fail light illuminated and its protective fuse actuated. The control logic for the Digital Feedwater Control system (DFWCS) is one of the electrical loads serviced by the UPS. Disruption of the DFWCS logic due to the electrical transient affected the feedwater system by driving the RFP controllers to minimum flow with no start signal being sent to the MFP per design. As a result, feedwater flow was lost to the RPV and the RPS actuated, as designed,when RPV Level 3 was reached.

Junk Plant Perry Gets Special inspection over Multiple Events

05000440


Way before the event that caused the special inspection, I documented I felt Perry was heading for trouble. Here is how I preemptively I documented my concerns. 
 
"Here I am today (2/29)just before the special inspection was announced. I thought it fishy Perry was admitting all the inaccurate event reports on the same swipe. Bet you Perry thought the special inspection inspector outsiders wouldn’t have the same deal as the onsite residents. We will ignore all initial event report mistakes and inaccuracies. So Perry came clean on their own.  

Perry must have been notified many days ago a special inspection was coming to their plant."   

(2/9 and 2/12)"I am disappointed the manual scam didn't come sooner. This is such a rare event, I am not sure their emergency procedures carry a specific event with two SRVs slamming open. You would think this is a so rare event and they never trained on it, they would emediately scram the plant.  This guy is so infrequent it calls for a special inspection."

(February 29, 2016) NRC Begins Special Inspection at Perry Nuclear Plant
The Nuclear Regulatory Commission has launched a Special Inspection into two recent events, neither of which affected public health or safety, at the Perry Nuclear Power Plant. The plant is operated by FirstEnergy Operating Co., and is located in Perry, Ohio, about 35 miles northeast of Cleveland.
Sounds like they didn't have valve position indication. They surmised SRVS were open because torus temperatures were screaming up.    
On February 8, operators manually shut down the reactor when they observed an increase of the temperature in the suppression pool. The suppression pool is designed to condense steam and is also a water source for emergency cooling systems. While the reactor was shutdown, on February 11, there was a temporary loss of power to certain plant cooling equipment.
 Operators were able to use a redundant system and restore power to the cooling systems.

“Even though the two events are not related we have questions related to the response of the equipment and operator actions. Our team of specialists in reactor operations and electrical equipment will review the technical details to better understand what happened,” said NRC Region III Administrator Cynthia D. Pederson.
A fairly large size team.  
The four-member inspection team began work on Monday and will spend time both on and off site conducting their reviews. After the inspection, a report documenting the team’s findings will be made publicly available.

Junk Plant Indian Point 2 Has Worst Capacity Factor Than River Bend


Seems they been stuck at 90% for more than a week?

Junk Plant Fermi Can't File A Clean Event Report.

This events were updated on Friday. Basically the RPS was supposed to be declared inop when these events occurred. This is very unprofessional. 

They assume the first time (1/06/2016) it was a actuator problem.

POWER REDUCTION DUE TO AUTOMATIC OPENING OF THE TURBINE BYPASS VALVES

"On January 6, 2016. at approximately 1514 EST, with Fermi 2 in Mode 1 operating at 100 percent reactor thermal power, the East and West Turbine Bypass Valves (TBVs) automatically opened for 3 minutes and 32 seconds in response to the number one High Pressure Turbine Stop Valve (TSV) drifting from full open to 25% open. Reactor power was subsequently lowered to 91.0 percent reactor thermal power and the bypass valves closed.

"Per Technical Specification Bases 3.3.1.1, TBVs must remain shut while reactor thermal power is at or above 29.5 percent to consider the TSV closure and Turbine Control Valve (TCV) fast closure Reactor Protection System (RPS) functions operable. The condition was recognized at the time of the event and the RPS functions were not declared inoperable since the functions were verified to remain enabled.

"Since the RPS functions were not declared inoperable, Fermi 2 did not report this event within 8 hours of occurrence. However, after further evaluation, it was determined that this event met the reporting criterion. Accordingly, this event is being reported pursuant to 10 CFR 50.72(b)(3)(v)(A).

"The licensee informed the NRC Resident Inspector."

The cause of the High Pressure Turbine Stop Valve drifting was due to an actuator malfunction that has since been corrected.

This event was determined to be reportable at 1200 EST on 02/24/16. See EN #51756 for a similar event that occurred on 02/21/16.
This is the second time (2/02/1016) the turbine bypass flings open? 

It is now called a "communication card failure" not a actuator problem.

MANUAL SCRAM DUE TO LOSS OF TURBINE BUILDING CLOSED COOLING WATER
It starts out as a leak in the Turbine Building Closed Cooling> So this event occured on Sept 13 and it takes them all this time to fix the event report. Sounds like the NRC provoking Femi to fix inaccurate 
"At 2305 EDT on September 13, 2015, a manual scram was initiated in response to a loss of all Turbine Building Closed Cooling Water (TBCCW). All control rods fully inserted. The lowest Reactor Water Level (RWL) reached was 137 inches. All isolations and actuations for RWL 3 occurred as expected. Decay heat was initially being removed through the Main Turbine Bypass System to the Main Condenser, however, as a result of the loss of TBCCW, the Main Feed Pumps lost cooling and had to be secured. At 2310, Standby Feedwater was initiated and Main Feedwater was secured.

"The loss of TBCCW also caused all Station Air Compressors (SACs) to trip on loss of cooling. The loss of SACs caused the Instrument Air header pressure to degrade to the point at which the Secondary Containment isolation dampers drifted closed. This resulted in the Reactor Building vacuum exceeding the Technical Specification limit. At 2325, operators started the Standby Gas Treatment system and manually initiated a Secondary Containment isolation signal. Secondary Containment vacuum was promptly restored to within Technical Specification limits. Additionally, Operators were monitoring for expected MSIV drift due to the degraded Instrument Air header pressure. When outboard MSIVs were observed to be drifting, Operators closed the outboard and inboard MSIVs at 2345. At 2352, Safety Relief Valves (SRVs) reached the Low-Low Setpoint and began cycling to control reactor pressure.

"RWL is currently being maintained in the normal level band with the Standby Feedwater and Control Rod Drive systems. Reactor Pressure is being controlled with Safety Relief Valves. Operators are currently in the Emergency Operating Procedure for Reactor Pressure Vessel control. Investigation into the loss of TBCCW continues.

"No safety-related equipment was out of service at the time of the event. All offsite power sources were adequate and available throughout the duration of the event.

"The NRC resident inspector has been notified."

* * * UPDATE AT 0555 EDT AT 09/14/15 FROM CHRIS ROBINSON TO JEFF HERRERA * * *

"At 0409 EDT the Reactor Core Isolation Cooling (RCIC) system was placed in service due to identification of an unisolable leak in the Standby Feedwater System. Reactor water level and pressure is now being controlled though the RCIC system and Safety Relief Valves. This event update is reportable as a valid manual initiation of a specified safety system under 10CFR50.72(b)(3)(iv)(A).

"The NRC resident inspector has been notified."

The leak rate was reported as approximately 5-10 gallons per minute from a weld on the standby feedwater pump header drain valve F326. The licensee reported the leak stopped once RCIC was placed into service. The licensee is still investigating the issue.

Notified the R3DO (Pelke), IRD Manager (Grant), NRR EO (Morris).

* * * UPDATE PROVIDED BY CHRIS ROBINSON TO JEFF ROTTON AT 2135 EDT ON 09/14/2015 * * *

"At 1847 EDT on September 14, 2015, a valid automatic Reactor Protection System (RPS) actuation occurred due to Reactor Water Level 3 while shutdown in MODE 3. Operators were manually controlling Reactor Pressure Vessel (RPV) level and pressure with Reactor Core Isolation Cooling (RCIC) and Safety Relief Valves (SRV). While operators were cycling SRVs, the RPV level went below the Level 3 setpoint. Operators promptly restored RPV level by manual operation of RCIC. The Level 3 actuation and associated isolations were verified to operate properly.

"The scram signal has been reset. Fermi 2 remains in MODE 3 controlling RPV Level and Pressure through manual operation of RCIC and SRVs.
So they got a scram on cycling SRV valves twice. It indicates problems with training.  
"This is the second occurrence of a valid specified safety system actuation reportable under 10CFR50.72(b)(3)(iv)(A) for this ongoing event.

"The NRC Resident Inspector has been notified."

Notified R3DO (Riemer), IRD Manager (Grant), and NRR EO (Morris)

* * * UPDATE FROM BRETT JEBBIA TO JOHN SHOEMAKER AT 1446 EST ON 2/27/16 * * *

"This update provides clarification of the applicable reporting criteria for this Event associated with primary containment isolation actuations.

"Upon the manual reactor scram at 2305 EDT on September 13, 2015, Reactor Protection System (RPS) Level 3 actuated and Primary Containment Isolation System (PCIS) Groups 4, 13 and 15 actuated as expected. The applicable reporting criterion for these actuations is 10 CFR 50.72(b)(3)(iv)(A).

"The applicable reporting criterion for the manual closure of the inboard and outboard main steam isolation valves at 2345 EDT on September 13, 2015, is also 10 CFR 50.72(b)(3)(iv)(A). In addition, the manual closures of all MSIV lead to a loss of condenser vacuum which resulted in the actuation of PCIS Group 1 at 0001 EDT on September 14, 2015, as expected. The applicable reporting criterion for this actuation is also 10 CFR 50.72(b)(3)(iv)(A).

"Upon reaching Level 3 at 1847 EDT on September 14, 2015, PCIS Groups 4, 13 and 15 actuated as expected. The applicable reporting criterion for this actuation is 10 CFR 50.72(b)(3)(iv)(A).

PSEG: New Official at Junk Nuclear Fleet Operator?

Can he straighten out and fix the junk?

Or is he going to help run it until it can't be fixed any more, or not worth fixing?

Here we can see the symbioses of the military, working as a NRC resident inspector and becoming a senior executive of a fleet operator...

Why did he pick such a small fleet operator with all his big credentials?

More Safety Breaker Problems at Junk Plant River Bend.

So where is the reset button to make a plant, fleet, employees and management all new. Where is your reset?  We all deserve a second, third, forth and fifth chance. So where is our next second chance? 

I like riding my mountain bike in the small mountains around my house. I spend a tremendous amounts of time on my bike seat. Being outdoor and in nature reminds me how close we all are to the infinite and god. It is just right there without any deniability. I am heading out to the infinite right now.

It is like coming to a swampy area on my bike. Five or six mosquitoes are on my arm and many more attached to my body. I am getting extremely uncomfortable. I can imagine itching for hours. It's like swatting one mosquito to death on my arm and wondering why I am still being attacked by a cloud of bugs. I should be not thinking stupid thoughts at all, but moving my bike(me)bike out of the swamp.

Honestly, I would never give up on the human spirit and our intelligence. The ability of people to dig a hole nobody can imagine them getting out of. The ability of person at any point, to transform their lives. We are all one higher choice away from a world we dream of. Maybe it not dream at all, but a world god provides for us. It is our choice.  

I don't think this event went down this way they said it did. I think Entergy was worried the NRC would request a shutdown. Or the NRC hinted they might do that. 

Basically by March of 2015 the NRC and Entergy realized they have systemic breaker quality and reliability issues at River Bend. It is unbelievable after all this time and the special inspection, they would discover new breaker problems at River Bend. 

What would a plant reset look like to you?

ELECTRICAL BREAKER ISSUE IDENTIFIED DURING AN ENGINEERING REVIEW

"At 1100 CST on February 24, 2016, with the plant in cold shutdown (Mode 4), the shift manager was notified of a condition that could potentially prevent the automatic closure of the circuit breakers powering the emergency ventilation fans in the both the Division 1 and 2 emergency diesel generator rooms. These fans are not in Technical Specifications, however, they provide a support function to the emergency diesel generators, requiring that both diesel generators to be declared inoperable. This inoperability constitutes a condition that could potentially prevent fulfillment of the safety function of onsite AC power sources, and is being reported pursuant to 10 CFR 50.72(b)(3)(v).

"Four additional breakers are affected by the same condition. These breakers supply power to Division 1 and 2 containment unit coolers and the Division 1 and 2 auxiliary building 141 ft. elevation general area unit coolers. The auxiliary building unit coolers are not in Technical Specifications, however, they provide a support function to the electrical distribution system. The Technical Specification required action is to declare both trains of the residual heat removal system (shutdown cooling mode) inoperable. This inoperability constitutes a condition that could potentially prevent the fulfillment of the decay heat removal safety function, and is being reported pursuant to 10 CFR 50.72(b)(3)(v).

"Division 2 residual heat removal is operating in shutdown cooling, satisfactorily maintaining reactor coolant temperature. The affected breakers can be manually operated to start/stop their associated equipment, if necessary for operation."

This condition was identified during an Engineering review. The licensee has compensatory measures in place. Long term corrective actions are under review.

The licensee informed the NRC Resident Inspector.




(Feb 24, 2016@ 5pm) "Yea well, right after the 2014 Christmas plant trip I noticed the troubles River Bend was having controlling vessel water level. Don’t even get me talking about all the plant trips nationwide in the industry, with them having feedwater control system problems. My favorite recently is Callaway. They partially reverse-engineered an obsolete aux feed water safety controller cards. It is cheaper to replace a card than replace the system (“Failure to assure that the design of the replacement reverse engineered Modutronics controller cards for the auxiliary feedwater control valves were suitable for their application”). 
So I looked at a bunch of LERs about plant trips at River Bend. In most of the trips, the level was unprofessionally banging from the high feed pump trip to the low level scram. I doubt you could call it control. The feed pumps were constantly tripping also. I just couldn’t believe how they were getting away with acting so unprofessional scram after scram. So I made out notes on my blog…I talked to the senior resident explaining the problem. He flipped it into an allegation, I hate the NRC’s allegation
department. They in turn called a special inspection. They discovered known massively leaking feed regulating valves and the simulator had serious fidelity problems. No wonder they didn’t know how to control reactor vessel level. Here is the NRC’s response to me. 
“NRC: Proof I instigated The 2014 Christmas River Bend plant Scram Special Inspection” 
In this response, the NRC says in investigating my vessel level problem, the NRC discovered an almost identical issue with ventilation breaker. The NRC said I caused two special inspections. It startles me to death to think the licensee and NRC can’t figure this out without an outsider provoking them. 
“Junk Plant River Bend’s Crazy February 2016 Power History So Far...” 
Here I am explaining River Bend’s disgusting recent capacity factor problems on my blog. I again called the senior resident inspector. Basically she told me the down-powers and shutdowns are caused by a host of equipment problems. She wouldn’t get specific. She won’t tell me why they shutdown on Fed 16. River Bend is in a lot more trouble than the ROP and inspection reports disclose. 
Since the 2014 Christmas trip River Bend has had three special inspections. It’s got to be a record. The three special inspections are: the 2014 Christmas scram, the magniblast breaker issue and the recent lightning scram where they flubbed putting on shutdown cooling. I am dying to see if River Bend controlled vessel level in the lightning scram?

NRC Allegation response to me: “Based on the multiple failures of the feedwater system, the potential generic concern with the Magne Blast circuit breakers, and the issues related to reactor vessel level between the Level 3 (low) and Level 8 (high) setpoints following a reactor scram, the NRC determined that the appropriate level of NRC response was to conduct a special inspection.”"

Junk Plant Hope Creek: PSEG's Frivolous Denial Of NRC Non Sited Violation

works in progress

Originally posted 2/28

I have felt guilty for weeks with not commenting on this inspection report and the licencee not accepting the NRC's minimalist finding. They are wasting the NRC's time and their own. 

Basically the industry has been recently trying to dial down the CDBI inspections in regulatory reduction. It is as wasting everyone's time.

I think the gist of this stupid is Hope Creek violation was preforming a intentional experiment on the plant. The NRC gave Hope Creek a gift...then they wouldn't accept the gift. They were having troubles with this valve for years with leaking and they didn't have a adequate safe replacement. They gambled if they turned the valve around from normal...had the flow holding the valve shut against pressure, it would fix the leak. They valve was never designed for this duty, basic engineer work...so there was much more friction opening and closing this valve.

I think this is a symtom of a attitude problem with Hope Creek, they are trying to disrupt and weaken NRC authority and oversight over frivolous non sited violation regulatory disputes. It like a cop stops you for speeding and he then lets you off with just a verbal warning.

SUBJECT: RESPONSE TO DISPUTED NON-CITED VIOLATION HOPE CREEK GENERATING STATION – COMPONENT DESIGN BASES INSPECTION REPORT 05000354/2015007 
Dear Mr. Davison: 
We received your response [ADAMS No. ML15362A564] to our inspection report
 05000354/2015007 [ADAMS No. ML15329A157] issued on
November 25, 2015, concerning activities conducted at your facility. In your response, you denied a Non-Cited Violation (NCV) contained in the inspection report. Specifically, PSEG contends that “the weaknesses identified in the inspection report regarding classification, evaluation and corrective actions are not more than minor in that PSEG’s conclusion on operability and corrective actions were not impacted.” 
The NRC conducted a detailed review of your response and the applicable inspection guidance. Region I staff who were not involved with the initial inspection effort performed this review. After careful consideration of the bases for your denial of the NCV, we determined that the violation and characterization of the finding were properly described in the inspection report. Specifically, the inspection team identified that your staff failed to conduct operability determinations in October 2013 following the improper installation of a service water system valve and a subsequent event where the valve failed to operate due to a high torque condition. In response to the inspection team’s questions, your staff, with support from an external engineering organization, performed an operability review and determined that the valve was able to perform its safety function for a limited number of operating cycles. You subsequently scheduled a maintenance activity to fully restore the valve during the October 2016 refueling outage. Our review determined that this finding was appropriately characterized as “more than minor” as there was a reasonable basis for questioning operability of the valve following the October 2013 events described above. We have provided a summary of our evaluation and conclusions as an enclosure to this letter. 
SUMMARY  
Non-Cited Violation (NCV) 05000354/2015007-02

Restatement of the Violation:

The team identified a Green NCV of 10 CFR Part 50, Appendix B, Criterion V, “Instructions, Procedures, and Drawings,” because PSEG did not provide adequate work order instructions for the installation of service water (SW) pump discharge isolation valve 2198C following planned valve maintenance in October 2013. Specifically, the inadequate work order instructions contributed directly to maintenance technicians installing the valve in the opposite orientation compared to the intended orientation.

Licensee Response (Summary): 
PSEG denies that the NRC identified any new information that impacted the licensee’s conclusions regarding operability or corrective actions. The improper re-installation of the valve EAHV-2198C was promptly identified by the licensee and entered in CAP, and the additional analyses performed in response to NRC questions supported the licensee’s initial conclusions. 
In addition, PSEG contends the identified weaknesses associated with the classification, evaluation, and corrective actions of EAHV-2198C do not meet the threshold for more than minor.

NRC Evaluation: 
The NRC Region I staff performed an independent review of the documented NCV in Inspection Report 05000354/2015007, using PSEG’s basis for denial for comparison, and made the following observations:
1) Notification (NOTF) 20626219 was initiated by the PSEG staff on October 22, 2013, identifying the installation of valve 2198C 180 degrees different than when removed. This NOTF was subsequently updated by the PSEG maintenance staff to reflect inadequacies in the applicable Work Order (60112463-410) as compared to the valve drawing (M-10-1) and the associated vendor manual. The NCV properly refers to 10 CFR 50, Appendix B, Criterion V, as the appropriate violation of regulatory requirements.
2) The Component Design Bases Inspection (CDBI) report states (page 6) that “there was no documented evaluation of the impact of this misalignment and configuration error prior to operations declaring the C SW pump operable following the 2198C maintenance on October 23.” As stated in the report and further clarified by interview with the inspection team leader, PSEG did not complete an operability evaluation prior to restoration of the C SW pump to service on October 23, 2013, in spite of the improper installation of the outlet valve. Further, PSEG acknowledged this deficiency by initiating NOTF 20705874 (also documented in the report). The inspection report (page 7) identified a second instance where PSEG failed to properly assess a valve operational anomaly, an unexpected high opening torque (compared to the valve’s weak link analysis and Limitorque limits) and its potential adverse impact on system operability.This condition was identified during troubleshooting of valve 2198C on October 27, 2013, but no corresponding operability evaluation was documented.
3) The team’s observations documented in the report and highlighted in 2) above, form the basis for the inspection team’s conclusion that the NRC added value to a licensee-identified finding or violation. The absence of an operability evaluation, for either of the above referenced conditions, was documented as a “weakness in the licensee’s classification, evaluation, or corrective action” (page 9) and was the basis for the team to conclude there was a reasonable doubt of operability, with respect to the valve being able to function under all design basis conditions. In order to conclude that the valve was operable and to answer questions from the inspection team, PSEG performed an operability determination for the issue of the valve being installed in the wrong orientation (NOTF 20705874), performed a technical evaluation to determine that the valve actuator was capable of opening the valve under all required design basis conditions based upon actual measured data (NOTF 20704783), and contracted with Kalsi Engineering to perform an H4BC gear box torque analysis for the valve actuator. This team conclusion was documented in the Analysis Section of the inspection report (page 9-10) in reference to the basis for the observations (and underlying performance deficiency) being more than minor. The team cites Example 3.j of IMC 0612, Appendix E, as justification of the more than minor determination. 
4) PSEG’s Basis for Denial did not address the Appendix E more than minor example referenced in the CDBI inspection report. Rather, PSEG stated that the weaknesses identified by the team regarding classification, evaluation and corrective action were not more than minor. Further, PSEG contends that the additional analyses performed in response to NRC team questions did not change the original operability determination outcome. Neither the subjective contention of the weaknesses being minor nor the final determination of operability being maintained provide a sufficient basis for denial. The NRC determined that the Appendix E example established the basis for determining that this performance deficiency was of more than minor significance.
5) In the Basis for Denial, PSEG opines that the CDBI team’s challenge of the operability impact of the above conditions was unfounded without knowledge of the actual operating conditions of the system (system alignment, flowrates, and valve differential pressure were not recorded and were unknown). PSEG contends that without knowing actual system operating conditions, data cannot be extrapolated with any certainty. The NRC considers that the uncertainties associated with the valve operating parameters highlight the reason why PSEG was required to perform an operability determination following improper installation of the valve and its failure to operate due to a high torque condition.
6) Additionally, PSEG took exception to the observation in the inspection report that the maintenance work instructions lacked sufficient detail. On page 6 of the inspection report, the inspection team noted that PSEG maintenance personnel identified and documented in NOTF 20626219, that the desired orientation of the 2198 valve was not specified in valve drawing M-10-1 or in the vendor manual. The inspection team also noted that the work order contained several diagrams which depicted the wrong valve orientation. The NRC determined that the maintenance work instructions given to the maintenance staff lacked sufficient detail to ensure that the valve was installed in the proper orientation.
For the above reasons, the staff concludes that the violation occurred as described in Inspection Report 05000354/2015007.

Junk Plant Hope Creek: Paul Krohn and Safety Related "SW Pump Discharge Isolation Valves"

Updated 2/24
The NRC says now, the three valves are in the normal reverse orientation direction and the offending one is in the non-reverse orientation. All four valves after this 2016 refueling outage will be in the reverse engineering direction. The NRC is convinced all the valves will meet their intended safety function with all the new engineering evaluations. The NRC says they gave Hope Creek much value added with sw discharge valve CDBI inspection results. The NRC was always concerned with the level of engineering detail over these valves.   

The NRC seems to be saying prior to 2013 with all of the valves in the normal reverse orientation…they were always operable. I have questions on that. Looking in the reverse mirror might indicate that, but what proof did they have in 2012?

I asked when these SW discharge valves with reverse orientation were installed. They didn’t know for sure. Where they installed on new construction or did they put them in post construction…could you give me the date? Did the NRC give permission with the reverse orientation? They said it would have to go past their boss.

Talk to NRC today about this.

Mr. Krohn,

I am a safety advocate. I had recent issues with Hope Creek’s SRV setpoint lift inaccuracies and my issues were placed on the docket. We are watching Hope Creek very carefully. You signed off on the below IR.

Entry on my blog:

“Junk Plant Hope Creek: PSEG's Frivolous Denial Of NRC Non Sited Violation”

 
My friends and I were debating this issue this morning. We think this issue deserves a much higher violation level. 

So why wasn’t Hope Creek required to ask NRC permission to put all the safety related “sw pump discharge isolation valves (4 of them)” in the “intentionally reverse direction”?  Why didn’t they fulfill the requirements of 50:59? Why wasn’t this in the inspection report? Why wasn't the public immediately informed of this licensing deviation through a safety evaluation?  

We feel if Hope Creek was required to ask NRC permission, they would have taken the easy way out and then put in the proper quality valves for the intended duty. They would have properly fixed these leaking valves when the symptoms first was seen?  It’s pretty pathetic the NRC didn’t immediately flip this 2013 event up into a regular inspection report.  

We think collectively Hope Creek and the NRC has systemic “Normalization of Deviance” on steroids big time???

I believe I have spoken to you in the past and you are one of the good guys. Did we talk about the structure of the CDBIs? The public meeting? Do I remember it right, with all the nuke guys bitching about how useless the CDBIs were, and a diversion from safety?   

Could we have a discussion just about this particular issue?

I never have any confidentiality or anonymity needs what-so-ever.

Hope Creek Generating Station - Component Design Bases Inspection Report 05000354/2015007

Description. 1 EAHV-2198C is the 'C' SW pump discharge isolation valve. The valve is a 28- inch Weir Tricentric butterfly valve with a SMB-1/HBC-4 (60-1) Limitorque motor operator. The valve has an active safety function in the open position to provide normal SW flow to the safetyrelated safety auxiliaries cooling system (SACS) heat exchangers (HXs) and non-1 E reactor auxiliaries cooling system (RAGS) HXs, and emergency SW flow to other systems. PSEG had originally intentionally installed all four 1 EAHV-2198 valves in the reverse flow direction to permit the downstream header pressure to seat the valve tighter to minimize seat leakage during SW pump and strainer on-line maintenance.

"The previously installed Temperature Transmitters were Fisher Controls transmitters; model PM511, an original electronic transmitter from the 1970s. Model PM511 is obsolete and replacement parts were running out so an Engineering Equivalent Change evaluated using an alternative model. The new Moore Industries
temperature transmitters, model RBT/3W20-40/4-20mA/117 AC/-EZ84.06-LNP-VTD[EX], were procured from Moore Industries International and Nutherm International performed the Commercial Grade Dedication."
The industry would say this equipment would be needed so infrequently that not shutting down when required by tech Specs is, the risk is insignificant. I am saying if the plant doesn’t pay a steep price for incompetence with purchasing poor quality new safety components( shutdown per tech specs), then the industry will keep calling events like this to their doorstep.

LER: 2015-008 


Dec 18, 2015: Part 21notification
July 31, 2015: First Failure

On 11/11/2015, a second failure
On December 18, 2015, James A. FitzPatrick Nuclear Power Plant (JAF) was operating at 100 percent power when a 10 CFR 21.21(d)(3)(ii) Notification was received from Nutherm International. It identified a defect in Moore Industries temperature transmitters. Specifically, insulation was damaged in the T2 transformer during assembly which could result in premature failure.

These components were installed starting in June 2015 at 27TT-113A and 27TT-113B in the Containment Atmosphere Dilution (CAD) system. The defect caused failures in July and November which resulted in either the “A” or “B” CAD subsystem isolating. Corrective actions included replacing both temperature transmitters with ones that were confirmed to not contain this defect.

Even though these defective temperature transmitters function appropriately until they fail, this defect reduced the reliability of the CAD system to perform its function for its entire mission time. Therefore, this deficiency resulted in a loss of safety function to mitigate the consequences of an accident, reportable per 10 CFR 50.73(a)(2)(v)(D). Also, a single cause affected the safety function of independent CAD trains, reportable per 10 CFR 50.73(a)(2)(vii)(D); and, this condition existed longer then allowed by Technical Specifications 3.6.3.2, reportable per 10 CFR 50.73(a)(2)(i)(B).

Background

The Containment Atmosphere Dilution (CAD) system [EIIS designation: BB] functions to maintain combustible gas concentrations within the Drywell and Torus [BT] at or below the flammability limits following a postulated loss of coolant accident (LOCA) by diluting hydrogen and oxygen with nitrogen. Also, the CAD system provides the pneumatic supply to instruments and controls inside the Drywell; including the long term (100 day) pneumatic supply to the Automatic Depressurization System (ADS) valves [SB] and accumulators following a LOCA…

Event Description 
On December 18, 2015, James A. FitzPatrick Nuclear Power Plant (JAF) was operating at 100 percent power when a 10 CFR 21.21(d)(3)(ii) Notification was received from Nutherm International. It identified a defect in Moore Industries Resistance Temperature Detector (RTD) temperature transmitters supplied to JAF. The transmitters were installed at 27TT-113A and 27TT-113B in the CAD System. A failure of 27TT-113A initiates a closure of CAD subsystem “A” isolation valves 27AOV-128A and 27AOV-129A. A failure of 27TT-113B initiates a closure of CAD subsystem “B” isolation valves 27AOV-128B and 27AOV-129B. Isolating either CAD subsystem impacts the containment makeup capability and the Instrument Nitrogen Header. An Operability Evaluation determined that this defect reduced the reliability of the CAD system such that it may not be able to meet its full 100 day mission time.

This condition was reported to the NRC per 10 CFR 50.72(b)(3)(v)(D), ENS 51613, as a condition which could have prevented the fulfillment of a safety function to mitigate the consequence of an accident.

Event Analysis

The previously installed Temperature Transmitters were Fisher Controls transmitters; model PM511, an original electronic transmitter from the 1970s. Model PM511 is obsolete and replacement parts were running out so an Engineering Equivalent Change evaluated using an alternative model. The new Moore Industries temperature transmitters, model RBT/3W20-40/4-20mA/117 AC/-EZ84.06-LNP-VTD[EX], were procured from Moore Industries International and Nutherm International performed the Commercial Grade Dedication.

The new Moore temperature transmitter contained a defect which first failed on 7/31/2015 in 27TT-113A.

When 27TT-113A failed the “A” CAD subsystem automatically isolated by closing the supply valve 27AOV 128A and backup valve 27AOV-129A. This failure was initially identified as component infant mortality and the component was replaced with a spare component.

On 11/11/2015, a second failure of a new Moore temperature transmitter occurred at 27TT-113B. In a similar fashion to the 7/31/2015 failure, “B” CAD subsystem automatically isolated by closing the supply valve 27AOV-128B and backup valve 27AOV-129B. Based on this now being the second failure of newly installed components, there was increased scrutiny placed on this failure. The components were returned to Nutherm to perform a failure analysis.

The December 18, 2015, Part 21 notification from Nutherm informed JAF that the wire insulation in T2 transformer on the Moore Industries RTD temperature transmitter was damaged during assembly. This damage reduced the insulation resistance and dielectric breakdown between the windings of the transformer; resulting in premature failure of the temperature transmitter.

It has been determined that no visual inspection of the transformer or testing after the transformer is installed will discover this defect. This defect can only be found by performing testing on the transformer prior to installation.

The investigation into the two failures on 7/31 and 11/11 became the driving force which led to the Part 21 Notification on 12/18. The replacement spares installed after the two failures were the two serial numbered components included in the Part 21 Notification made to JAF. The removed failed components were also determined to contain the same defect as the Part 21 Notification.

With no method available to inspect the potentially degraded subcomponent after installation, there is not a reasonable assurance the two components would have been able to meet their required 100 day mission time. This condition could have prevented the fulfillment of a safety function, reportable per 10 CFR 50.73(a)(2)(v)(D). This condition caused two independent trains to be Inoperable in a single system designed to mitigate the consequence of an accident, reportable per 10 CFR 50.73(a)(2)(vii)(D). Technical Specification (TS) 3.6.3.2 requires the CAD system to have two Operable subsystems. On June 17, 2015, when the first defective temperature transmitter was installed, “A” subsystem was Inoperable. Required Action A.1 of the TS requires that it be restored within 30 days. On July 2, 2015, a second CAD subsystem became Inoperable when a second defective temperature transmitter was installed. Required Action B.2 requires that one CAD subsystem be restored within 7 days. When this was not accomplished, Required Action C.1 requires that the plant be in Mode 3 within 12 hours. Since JAF was not in Mode 3 within the required completion time, this event was a condition prohibited by Technical Specifications, reportable per 10 CFR 50.73(a)(2)(i)(B).

Cause

The cause of this event is a defect introduced during the manufacturing of temperature transmitters 27TT- 113A and 27TT-113B installed in the Containment Atmosphere Dilution system which resulted in decreased system reliability.
