| ENS 47039 | 8 July 2011 16:00:00 | This notification is being made under 10 CFR 50.72(b)(2)(xi) of a situation related to the protection of the environment for which a notification to a state agency has been made. On July 8, 2011, South Carolina Electric & Gas Company (SCE&G) made a voluntary notification to the South Carolina Department of Health and Environmental Control (SCDHEC) in accordance with the Nuclear Energy Institute (NEI) Groundwater Protection Initiative for an on-site leak that may exceed 100 gallons. The leak was entirely contained within the V. C. Summer Nuclear Station site boundary. On July 7, 2011 during a routine inspection, a leak was discovered in a liquid radwaste line upstream from its final discharge point and downstream of the release radiation monitors. This line contains processed liquid radwaste that has been sampled and permitted for release. The leak occurred inside a containment enclosure which overflowed. The enclosure was drained and the liquid was returned to the plant for disposal. The leak has been isolated and all radwaste release via this pathway has been suspended. The last inspection of this equipment was conducted on February 14, 2011, and revealed no external leakage. The licensee notified the NRC Resident Inspector. |
| ENS 46899 | 27 May 2011 14:50:00 | At 1200 hours on May 27, 2011, the plant was in Mode 3 during startup from a refueling outage with the main steam isolation valves closed. When the 'C' main steam isolation valve was opened for stroke testing, a safety injection occurred. The safety injection was due to a differential pressure of greater than 97 PSIG between the 'C' main steam line and the other main steam lines. The emergency core cooling system started and injected water into the Reactor Coolant System. All systems responded as expected. Safety injection was secured and the plant was stabilized in Mode 3. The licensee has notified the NRC Resident Inspector. Licensee will be notifying the State and local government. |
