"Reportable oil spill (Teresstic 68, approximately 1 gallon) into the discharge of Keowee Hydro Station tailrace (Keowee River). Source of the release was the Keowee Hydro Station sump. The release is NOT continuing. Operation of units 1, 2, and 3 are unaffected.
"At request of HAZMAT teams for safety during investigation and recovery of oil, commercial operation of Keowee Hydro units is restricted. Emergency operation of Keowee Hydro Units is unaffected.
"HAZMAT teams have placed oil absorbent boom across Keowee Hydro tailrace (Keowee River) to contain/collect oil."
The licensee contacted the Coast Guard via the National Response Center (event #847958), the State Emergency Response Committee, Oconee County Center, and Pickens County Center.
The licensee notified the NRC Resident Inspector. |

"At 1312 EDT, the Harris Nuclear Plant (HNP) discovered that the Harnett County Warning Point could not be contacted while doing weekly communications drill in the Main Control Room. At 1345 Harnett County Warning Point was contacted using the Bell South phone line and Harnett County stated that the phone lines had been damaged and the Harnett County Warning Point could not receive or transmit communications from approximately 1100 to 1340 hours. HNP verified that communications are presently available for the State of North Carolina and all four counties within the 10-mile emergency planning zone. Only the Selective Signaling System to Harnett County remains inoperable and under investigation for repair. This requires an 8-hour non-emergency notification per 10CFR50.72(b)(3)(xiii) due to the loss of a significant portion of the offsite notification system. The NRC Resident Inspector was informed."
The licensee has a compensatory measure of communication via an alternate phone line to Harnett County. |

A relief valve (BG 8117) in the letdown system opened and released about 650 - 700 gallons of water from the reactor coolant system into the pressurizer relief tank. The rate of release from the letdown was 119 gpm. It was estimated that the pressurizer level lowered about 2-3%. The letdown system was isolated by closing the letdown orifice block isolation valve. Licensee is investigating the reason for the spurious lifting of the relief valve. Due to leakage from the reactor coolant system, the licensee entered EAL 4R. Plant is stable and operating at full power.
The licensee notified the NRC Resident Inspector.
