At 1712 EDT on 9/8/2021, V.C. Summer made Event Notification 55450 notifying the NRC of an environmental report to another government agency, in accordance with 10 CFR 50.72(b)(2)(xi). In the course of station response, it was determined that the lift station overflow did not exceed any federal, state or local reporting criteria or violate any permits. Following this investigation, the report to the South Carolina Department of Health and Environmental Control is considered a courtesy notification and the event does not meet reporting criteria under 10 CFR 50.72(b)(2)(xi).

| ENS 54495 | 27 January 2020 04:54:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Inadvertent Activation of an Early Warning Siren | At 2354 EST, on January 26, 2020, officials with the State Emergency Operations Center and Newberry County, SC were notified of an apparent inadvertent actuation of a single siren in the VC Summer Early Warning Siren System (EWSS). (VC Summer Nuclear Station) VCSNS received a report of siren actuation from a local resident at approximately 2340 EST. The EWSS indication at the Emergency Operations Facility showed siren #35 had actuated. A reset of the EWSS was performed. VCSNS is working to confirm actual siren activation and troubleshoot the issue. This event is still under investigation. This is a non-emergency notification of other government agency. This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi). The NRC Resident Inspector has been notified. The Licensee notified state and local agencies.
The investigation of this event has concluded that EWSS siren #35 did not actuate. This conclusion was reached after interviewing residents who reside directly across the street from EWSS Siren #35, who confirmed that this siren did not actuate. Also, maintenance personnel investigations concluded that the local activation indication was erroneous, due to observed battery readings being normal. Had the siren actuated, its batteries would have been depleted or nearly depleted. The NRC Resident Inspector has been notified. Notified R2DO (Baptist). | ||

| ENS 47039 | 7 July 2011 15:00:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to a Contained On-Site Liquid Radwaste Leak | 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 42560 | 8 May 2006 16:30:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release 10 CFR 50.72(b)(3)(xiii), Loss of Emergency Preparedness | Early Warning Siren System (Ewss) Declared Inoperable | Intermittent radio functionality was noticed during routine radio operation at 1203. Radio checks were satisfactorily performed immediately after this occurrence; however, at 1230, the intermittent problem recurred. VCSNS declared that the siren control system would not operate at 1230. Our procedures require notification of the South Carolina Emergency Management Division and the local counties within 1 hour. Informal notifications to Fairfield and surrounding counties, and the State Area Coordinator were completed by 1242. Official notifications were made via the ESSX system at 1321. This report is being made to the NRC per 10CFR50.72(b)(3)(xiii) due to the loss of >25% of the EWSS. Additionally, this is being reported per 10CFR50.72(b)(2) (xi) due to the notification made to other government agencies. The local counties notified include Fairfield, Newberry, Richland and Lexington. The outage affects the entire EWSS. The licensee informed state/local agencies and the NRC Resident Inspector.
The EWSS has been returned to service. Notified R2DO (Munday) and NSIR (McMurtray) via email. | ||
| ENS 42436 | 21 March 2006 07:29:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to Inadvertent Emergency Siren Actuation | At approximately 0238 (EST), received first notification of an actuation of the Early Warning Siren System. This call came from Fairfield County 911 dispatcher after they received numerous calls from area residents. Subsequent calls were received from the State Warning Point, Lexington, Newberry and Richland County's 911 dispatcher as well as calls from the public. The Secondary Alarm Station informed the Control Room that when an attempt was made to silence one individual siren (N-86) that was in alarm, all the sirens were inadvertently actuated. Sirens appear to have alarmed for approximately three minutes and then shut off (per design). Subsequent investigation by the Emergency Preparedness group did not reveal any human error. The investigation into the siren actuation is ongoing. All sirens are operable at this time. SCANA Public Relations has been informed and will be preparing a press release, as will the SC Emergency Management Division. A local television station, WIS TV, will be interviewing SCANA Public Relations personnel at approximately 0630. The licensee notified the NRC Resident Inspector. | ||
| ENS 42432 | 20 March 2006 14:00:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification to South Carolina Department of Health and Environmental Control (Dhec) of Sewage Spill | The licensee reported that an onsite underground line to the sanitary sewage pond broke resulting in back drainage from the pond into the environment of an estimated 60,000 to 70,000 gallons of sewage. The pond sewage has gone into the yard drains and possibly some of the nearby creeks. The licensee provided the following information via facsimile: Approximately 0800 received first notification of discharge from Sanitary Aeration Pond, outfall # 005. At 0825 an initial notification was made to DHEC. Temporary covers were installed over the yard drains. These covers seem to be holding the remnants of the fluid. At 0900 the control room was notified the discharge had made it to the yard drains and thus to the environment. At 1240 the estimate of discharge was revised to 60,000 to 70,000 gallons, which made this potentially newsworthy. Suspected cause is a broken underground pipe. No impact on plant operation. The discharge was not radioactive. The licensee notified the NRC Resident Inspector. |
