DEGRADED CONDITION CAUSED BY RHR RELIEF VALVE LEAKAGE
"At 1455 EDT, [on 91/16/13], [Susquehanna] Engineering determined the leakage from the 2B RHR Pump Suction Relief valve caused the Engineered Safety Feature (ESF) Leakage to exceed the 2.5 gpm which was provided to the NRC during the implementation of the Alternate Source Term (AST) submittal. The calculated leakage rate was 7.5 gpm.
"This event is being reported as a degraded condition pursuant to 10CFR50.72(b)(3)(ii).
"Unit 2 is currently in Mode 4 (cold shutdown) for a maintenance outage."
This leaking RHR pump suction relief valve, previously identified in EN #49344, is being evaluated and repaired.
The licensee has notified the NRC Resident Inspector and the state.

OFF-SITE NOTIFICATION TO SOUTH CAROLINA DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL (SCDHEC)
"At approximately 0700 [EDT] on 9/16/13, site personnel discovered a sewer lift station, in the owner controlled area, overflowing. The overflow entered a nearby storm drain that discharges into Outfall 13. The estimated release volume is between 500-1000 gallons. The release has been stopped. At 1045 an initial notification was made to SCDHEC. A pump failure is suspected to be the cause of the back-up and subsequent overflow. Repair and clean-up is in process.
"The NRC Residents have been notified."
