Junk Plant Watts Bar 2 Fortuitous Scram Report Today

So why is a northern boy interested on this particular plant and at this point and time? The below document was not publically available until this morning. 

My two Watts Bar 2 blog articles were written about at 5 and 6pm yesterday. 

The trip also occurred yesterday at 8:59am.

The official big dogs are closely going to be securitizing the timing of this all. Either I am a prophet or somebody called me up?

I called the two officials (NRC/TVA) identified in the document Watts Bar Unit 2 MSPI Effectiveness Date submitted on my blog. Explained my problems. The MSPI document is Watts Bars trying to be exampled from the ROP performance Indicator system because they are a new plant. Generally they blame initial startup issues on getting the bugs out of a new plant (bathtub curve). My theme is all the plant trips, scrams and down powers comes from construction related incompetence, poor quality workmanship and components. The Plant and TVA needs another kick in the ass to straighten up. They need the full force of the ROP and MSPI to be applied to the plant and it's resultant documentation and inspections.

My theme is TVA is trying to fraudulently gain exemption from the MSPI to April 1, 2018. As example, TVA blames the collapse of main condenser as construction issue in the 1970s, implying our new construction guys and quality processes are exempt from accountability leading to plant operations today.  

As far as the Fort Calhoun simulations justifying this all, none of this is facts or science based. It seem this guys can come up with any computer crack pot simulation based on nothing justifying anything they want.

The nice Watts Bar 2 senior resident reminded me the main condenser is not a safety related system. "We don't spend much time on these systems", he said. But is it really a balance of plant system, it is more a intermediate system between safety and balance of plant non safety system. If the main condensers is available, then you don't test the safety cooling system. I'll make the case TMI emerged from broken or degraded non safety systems that cascaded into a nuclear event.

Event Text
MANUAL REACTOR TRIP IN RESPONSE TO INDICATION OF MULTIPLE DROPPED CONTROL RODS

"While operating at 97% power, the Watts Bar Unit 2 reactor was manually tripped at 0857 EST on December 11, 2017 due to multiple dropped control rods. All control and shutdown bank rods inserted properly in response to the manual reactor trip. All safety systems including Auxiliary Feedwater actuated as designed. The plant is stable with decay heat removal through Auxiliary Feedwater and the Steam Dump System.

"The cause of the dropped rods is being investigated.

"The manual actuation of the Reactor Protection System (RPS) is being reported as a four hour report under 10 CFR 50.72 (b)(2)(iv)(B). The actuation of the Auxiliary Feedwater System (an engineered safety feature) is being reported as an eight hour report under 10 CFR 50.72 (b)(3)(iv)(A).

"The NRC Senior Resident Inspector has been notified for this event."
