RESIDUAL HEAT REMOVAL SYSTEM DECLARED INOPERABLE
"At 0849 the B train of service water (SW) AC and DC power distribution systems [were] declared inoperable due to voltage fluctuations below the Tech Spec minimum. During this time the A train of RHR for Unit 1 was inoperable due to an equipment outage. LCO 3.0.3 [was] entered due to both trains [of] RHR inoperable on Unit 1. At 1029 Unit 1 exited LCO 3.0.3 when the A train of RHR was restored. Currently ground isolation efforts are in progress on the B train SW power distribution system."
The licensee notified the NRC Resident Inspector.

HIGH PRESSURE COOLANT INJECTION DECLARED INOPERABLE
"Unit 2 HPCI (High Pressure Coolant Injection) System was declared inoperable due to discovery of a failed flow controller. The controller failure would prevent HPCI from achieving rated flow (safety function). Investigation into cause of failure and preparation for controller replacement are in progress. This event is being reported under 10CFR50.72(b)(3)(v)(B & D)."
The licensee notified the NRC Resident Inspector.
The licensee indicated the Isolation Condenser is operable. A 14 day LCO is in effect.
