20190308 | IL_Clinton_1 | Retract HIGH PRESSURE CORE SPRAY SELF TEST FAILURE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53824

"On January 13, 2019, the Self Test System reported a fault associated with the logic system for the
High Pressure Core Spray (HPCS) high reactor water level closure function that could prevent the system from
performing its safety function.

The HPCS system was subsequently declared inoperable with actions taken per
LCO [Limiting Condition for Operation] 3.6.1.3 to close and deactivate the 1E12-F004 valve,
a primary containment isolation valve.

"Since HPCS is an emergency core cooling system and is a single train safety system,
this condition is reportable under 10 CFR 50.72(b)(3)(v)(D)
'Any event or condition that could have prevented the fulfillment of the safety function of structures or systems
that are needed to mitigate the consequences of an accident.'

"The NRC Resident Inspector has been notified."

HPCS is in a 14-day technical specification LCO action statement.


* * * RETRACTION AT 1908 EST ON 3/7/19 FROM JAMES FORMAN TO JEFF HERRERA * * *

"Testing of the logic system load driver card for the High Pressure Core Spray (HPCS) high reactor water level closure function
was completed both on site and at General Electric Hitachi (GEH).

This testing determined the cause of the self-test system fault report was limited to the self-test portion
of the load driver card and did not impact the ability of HPCS system to perform its specified safety function.

"Based on the testing results, this event is not reportable under 10 CFR 50.72(b)(3)(v)(D),
'Any event or condition that could have prevented the fulfillment of the safety function of structures or systems that are
needed to mitigate the consequences of an accident.'

Therefore, EN 53824 is being retracted.

"The NRC Resident Inspector has been notified."

Notified the R3DO (Hills).
