LOSS OF HIGH PRESSURE CORE SPRAY SYSTEM
"At 2338 PDT on September 24, 2019, the High Pressure Core Spray (HPCS) system was declared inoperable due to a leak on DSA-PCV-2C (2 inch Diesel Starting Air Pressure Control Valve). With one of two air headers isolated and being drained for maintenance, this leak caused the remaining starting air header for HPCS-GEN-DG3 (HPCS Diesel Generator) to lower to less than the operability limit.
"Upon declaring the HPCS system inoperable, TS 3.5.1 Action B was entered. In accordance with Action B, the Reactor Core Isolation Cooling (RCIC) system was verified to be operable. Action B provides a 14 day completion time to restore HPCS to an operable status.
"All other Emergency Core Cooling Systems (ECCS) were operable during this event. This event is being reported as an event or condition that could have prevented the fulfillment of a safety function credited for mitigating the consequences of an accident per 10 CFR 50.72(b)(3)(v)(D). The HPCS system is a single train system at Columbia.
"The leak was isolated and starting air header pressure restored to the HPCS diesel generator at 0104 PDT on September 25, 2019, and all associated Technical Specifications were exited.
"The NRC Resident Inspector was notified."
