HIGH PRESSURE CORE SPRAY SYSTEM DIESEL ROOM FAN MOTOR FAILURE

"On January 25, 2017, at 1836 PST, smoke was detected in the High Pressure Core Spray System (HPCS) diesel room with no indication of a fire. Investigation found the motor starter coil for DMA-FN-32 (Diesel Mixed Air Fan 32), HPCS diesel generator room normal cooling fan, failed. This fan is required for operability of the switchgear that powers the HPCS pump. The HPCS pump is currently inoperable due to maintenance being performed on other support systems.

"This condition is being reported under 10 CFR 50.72(b)(3)(v)(D) for an event or condition that could have prevented fulfillment of a safety function needed to mitigate the consequences of an accident.

"The licensee has notified the NRC Resident Inspector."

CONTAINMENT VALVES FAILED SURVEILLANCE TESTING

"On January 25, 2017, at 1800 CST, during planned surveillance testing, the Drywell Vent Line Inboard Isolation valve, CV-4302, was found to exceed its valve leakage limits and was declared inoperable. After completion of repairs to CV-4302, post maintenance testing showed that the Drywell Vent Line Outboard Isolation valve, CV-4303, was exceeding its valve leakage limits, and therefore, was declared inoperable at 0300 CST on January 26, 2017. This resulted in a containment penetration flow path not within purge valve leakage limits and is reportable in accordance with 10 CFR 50.72(b)(3)(v)(C).

"Repairs were completed on CV-4303 and both containment valves were declared operable at 1007 CST on January 26, 2017. Secondary Containment was operable at all times.

"The NRC Resident Inspector has been informed."
