ULTIMATE HEAT SINK TEMPERATURE EXCEEDED TECHNICAL SPECIFICATION LIMIT
"At 1454 EDT on 20 July 2014, Turkey Point Units 3 and 4 entered the Action for Technical Specification (TS) 3.7.4, Ultimate Heat Sink (UHS). The action was entered because UHS temperature exceeded the limit of 100 degrees F due to a natural event. This report is in accordance with 10CFR50.72(b)(3)(v)(B) because UHS capability to remove residual heat is impacted. At 1800 EDT the NRC verbally approved a natural event Notice of Enforcement Discretion (NOED) which allows the ultimate heat sink temperature to exceed 100 degrees F up to 103 degrees F. Unit power levels have been maintained at Unit 3 100% and Unit 4 95%.
"The NRC Resident Inspector has been notified."
* * * UPDATE FROM CHRIS TRENT TO DANIEL MILLS AT 2058 EDT ON 7/26/2014 * * *
"At 2046 on 7/20/14, Turkey Point Units 3 and 4 exited the Action for Technical Specification (TS) 3.7.4, Ultimate Heat Sink, when the ultimate heat sink (UHS) temperature decreased below the TS limit of 100 degrees F.
"At 1604 on 7/26/14, Turkey Point Units 3 and 4 entered the Action for TS 3.7.4, Ultimate Heat Sink. The action was entered because UHS temperature exceeded the limit of 100 degrees F.

SMALL KEOWEE HYDROELECTRIC STATION OIL DISCHARGED TO THE KEOWEE RIVER
"On 7/20/2014, at 1700 hours EDT, a spill of approximately five (5) gallons of Teresstic 68 lube oil was identified in the Keowee Hydroelectric Station (KHS) tailrace. Teresstic 68 oil is used at the station as an equipment lubricant. The KHS tailrace feeds into the Keowee River that leads into Lake Hartwell. The estimated area of the oil sheen is approximately 30x50 feet and a cleanup response is currently in progress. The cause of the spill was attributed to a faulty oil float switch in the KHS unwatering pump that allowed the oil to spill into the KHS tailrace (Keowee River).
"South Carolina Department of Health and Environmental Control (SCDHEC) and the National Response Center were notified of the spill on 7/20/2014 at approximately 2002 and 1953 hours [EDT] respectively.
"This event was determined to be reportable pursuant to 10CFR50.72(b)(2)(xi) due to the notifications to the SCDHEC and the National Response Center.
"The licensee notified the NRC Resident Inspector.
"Initial Safety Significance: The oil did not contain any plant produced radiological material and while contained, poses no safety risk with respect to the health and safety of the public.
"Corrective Action(s): The oil spill sheen is isolated to an approximate 30x50 foot area of the Keowee River. Because the KHS is currently not operating, the water spill area is stagnant, i.e., there is little or no movement of the water containing the oil sheen. The source of the leak has been contained and an investigation is underway to determine the actual cause of the spill. There was no impact on plant operations. The event was entered into the station's corrective action program."
