HIGH PRESSURE COOLANT INJECTION SYSTEM DECLARED INOPERABLE "At 1736 [CDT] on 26 April 2016, a licensed operator performing a control room panel walkdown noted the green standby light for the HPCI [High Pressure Coolant Injection] Auxiliary Oil Pump (AOP) was not illuminated. The bulb was replaced and the replacement bulb did not illuminate. A non-licensed operator (NLO) was dispatched to the local 250VDC starter rack. The NLO discovered the green standby light on the 250VDC starter rack had failed. An attempt was made to start the AOP with the control switch. The pump did not start. The AOP is required to start in order to open the steam admission valves for the HPCI turbine. "HPCI was declared inoperable at time 1754 [CDT] on 26 April 2016. Tech Spec LCO Conditions were entered and required actions completed. "HPCI is a single train system. This report is submitted as a condition that at time of discovery could prevent the fulfillment of the safety function of an SSC [Structure, System, and Component] needed to mitigate the consequences of an accident. "A similar condition was discovered on 25 April 2016 [see NRC Event #51882]. Corrective maintenance was performed and HPCI was declared operable following satisfactory completion of post work testing of the AOP. "Initial investigation indicates that the fault which occurred on 26 April is not the same as that which occurred 25 April. "Investigation is on going." The licensee has notified the NRC Resident Inspector

***Remember these are very infrequently operated machines. These guys are really susceptible age related failures and not constantly renewing and replacing aging components proactively. The turbine powered main feed pumps and turbine driven emergency feed are in the same category. The rub is, these pumps are obsolete and the repair and replacement part are increasingly getting disconnected from the machines. There just isn't enough technicians to service these obsolete machines

I am saying recentI have seen a lot of LERs and  events reports...there is a troubling trend of failures and not understanding the machine and its instrumentations up in the control room. They are very complicated machines.

Globally if you cut back money on training and maintenance, the unattended degradation problems would show up in new and reoccurring LERs and event reports.

This multiple and back-up electrical power sources nobody understands make these guys more unreliable. This philosophy just makes the machine more unreliable.

These event reports just popped up beginning yesterday. I find the number suspicious and troubling.

HIGH PRESSURE COOLANT INJECTION SYSTEM DECLARED INOPERABLE "On April 25, 2016, at 0607 hours [CDT], HPCI [High Pressure Coolant Injection] was isolated via the HPCI MO 2-2301-4 (HPCI Inboard Main Steam Isolation Valve) to stop a packing leak on the HPCI MO 2-2301-5 (HPCI Outboard Main Steam Isolation Valve). The packing leak was causing a steam plume potentially impacting the motor operator on the 2-2301-5 valve. HPCI was declared inoperable and T.S. 3.5.1 Condition G was entered. "Since HPCI is a single train safety system, this notification is being made in accordance with 10CFR50.72 (b)(3)(v)(D), as an event or condition that could have prevented the fulfillment of a safety function. "The NRC Resident Inspector has been notified."

HIGH PRESSURE COOLANT INJECTION SYSTEM DECLARED INOPERABLE "8-hour report due to HPCI inoperability. "At approximately 2109 [CDT] on 04/25/16, a licensed operator performing a control room panel walkdown noted the green light for HPCI Auxiliary Oil Pump (AOP) was not illuminated. The bulb was replaced and the replacement bulb did not illuminate. A non-licensed operator was dispatched to the local 250VDC starter rack. Both the green and red power indicating lights on the starter rack were found extinguished. An attempt was made to start the AOP with the control switch. The pump did not start. The AOP is required to start in order to open the steam admission valves for the HPCI turbine. "HPCI was declared inoperable at time 2117 [CDT], resulting in entry into Tech Spec LCO 3.5.1 Condition C - HPCI System Inoperable. Required Actions for Condition C are to verify by administrative means RCIC System is operable within 1 hour and restore HPCI System to operable status within 14 days. RCIC was verified operable by administrative means concurrent with HPCl declaration. "Troubleshooting activities for HPCI are being planned. "HPCI is a single train system. This report is submitted as a condition that at time of discovery could prevent the fulfillment of the safety function of an SSC [Structures, Systems, and Components] needed to mitigate the consequences of an accident." The licensee informed the NRC Resident Inspector.
