| ENS 46473 | 10 December 2010 04:04:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification - Agencies Notified of Onsite Tritium Leak | On December 9, 2010, elevated levels of tritium were identified in water samples taken from in-leakage into the below ground elevation of the diesel generator building (i.e., through underground conduit penetrations). The tritium levels were determined to be in excess of the Nuclear Energy Institute (NEI) voluntary reporting criteria (i.e., 30,000 pCi/L for onsite groundwater, as specified in the Offsite Dose Calculation Manual). Further investigation determined that the likely source of the tritiated water is buried piping located west of the diesel generator building. The area of the leak is inside the plant protected area, well inside the site's property boundary. There is no indication that tritium has migrated into drinking water sources or has migrated off plant property. The leakage has not impacted plant reliability or the operability of any safety-related equipment. Corrective actions taken were to capture the in-leakage of water into the diesel generator building and route it through our normal permitted discharge paths. Additional water samples will continue to be obtained from site monitoring wells until the source of the leak is isolated. Efforts to identify and isolate the source of the leakage, and plans for excavation of the suspected area, are in-progress. The Brunswick plant has had an extensive groundwater protection monitoring program in place since 2007. This environmental sampling program consists of more than 100 monitoring wells which are routinely sampled. The following agencies will be updated on the status of the onsite tritium samples: City of Southport, Brunswick County, State Officials, NEI, INPO, and ANI. The Licensee has notified the NRC Resident Inspector.
On December 10, 2010, at 2124 hours (EST), the buried piping leak was stopped after isolating the Unit 1 Condensate Make-up line to the Main Condenser (i.e., from the Condensate Storage Tank (CST)). The elevated levels of tritium are confined to the area in close proximity to the identified buried pipe location, west of the diesel generator building, well within the site's property boundary. The perimeter monitoring wells to the plant's protected area and site boundary continue to be analyzed with no increase in tritium levels identified. Preparations for the excavation and repair of the Condensate Make-up line are in-progress. The following agencies will be provided an update of this event: City of Southport, Brunswick County, State Officials, NEI, INPO, and ANI. The initial safety significance of this event is minimal. The Brunswick Steam Electric Plant has not identified any health or safety risk to the public or onsite personnel. There is no impact to plant reliability or safety. The Licensee has notified the NRC Resident Inspector." R2DO (Moorman) notified. | Main Condenser | |
| ENS 44885 | 2 March 2009 14:15:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Onsite Fatality | A contract employee associated with the Unit 2 refueling outage died this morning from an apparent heart attack. The death was not the result of any industrial safety issue and did not occur in a contaminated area. The individual was treated by the onsite first responders who administered CPR and AED (automatic external defibrillator). He was transported via ambulance to Dosher Memorial hospital where he was pronounced dead at 0915. OSHA is being notified of the event under the requirements of 29 CFR 1904. The licensee notified the NRC Resident Inspector. | ||
| ENS 44041 | 7 March 2008 15:30:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to Tritium in Onsite Water Samples | Brunswick previously reported detection of tritium in excess of Nuclear Energy Institute (NEI) reporting criteria on June 13, 2007, i.e., EN 43420, as a result of water samples taken from an onsite shallow groundwater well (i.e., ESS 1BC) near the Storm Drain Stabilization Pond (SDSP). As previously indicated in EN 43420, the storm drain system routes tritiated water into the SDSP. Overflow from the Turbine Building air-wash system was identified as the primary contributor to the effluent of the storm drain system. The air-wash is no longer routed into the storm drains, which eliminated the main source of the tritium into the storm drain system. On March 6, 2008, an ongoing investigation determined that tritium levels in excess of NEI voluntary reporting criteria present in an onsite shallow groundwater well (i.e., ESS-2C), resulted from a condition not previously reported. Though elevated levels of tritium for each incident are most likely a result of the same source (i.e., effluent routed in the storm drain system,) subsequent investigations indicate that the storm drain piping may allow an inadvertent pathway to groundwater in close proximity to ESS-2C. The monitoring well ESS-2C is well within the boundaries of the site owner controlled area and there is no indication that tritium has migrated into any drinking water. The following agencies will be updated on the status of the onsite tritium samples and informed of the pending press release: State Officials, City of Southport, Brunswick County, NEI, INPO, and ANI. The Licensee notified the NRC Senior Resident Inspector. | ||
| ENS 43695 | 5 October 2007 22:47:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Sodium Hypochlorite Spill While Offloading a Tanker Truck | At 17:20 the Brunswick Station control room was notified of a sodium hypochlorite spill. Approximately 300 gallons of a 15% solution was released to the environment through a faulty hose fitting at a tanker truck before it could be isolated. The state is required to be notified of any hazardous chemical release greater than or equal to 100 pounds (64 gallons of a 15% sodium hypochlorite solution corresponds to 100 pounds). The North Carolina State Division of Water Quality was notified of the event at 18:47 as required by 40 CFR 355.40. The US Coast Guard (report number 850864) and Brunswick County were also notified of the event. Minimal impact to the environment. No impact to the health and safety of the public. No impact to plant safety or operations. The licensee notified the NRC Resident Inspector. | ||
| ENS 43420 | 13 June 2007 12:00:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Notifications Made for Detection of Tritium in Onsite Water Samples | On May 8, 2007, measurable levels of tritium were identified in two manholes (i.e., MW-5 and MW-6) that route cable to a nearby meteorological tower. The manholes are located within the boundaries of the site owner controlled area. The manholes are also in close proximity to the Storm Drain Stabilization Pond (SDSP). The SDSP is an area of approximately 64 acres consisting of a non-lined perimeter dike of approximately 12 to 15 feet in height. The site storm drain system collects in the storm drain collector basin and is then pumped to the SDSP. The storm drain collector basin receives overflow from the Turbine Building air-wash system, which contains very small amounts of tritium. By plant design, the tritiated water of the SDSP is then pumped into the intake canal during monitored, controlled releases, compliant with all permits and regulations. As a result of ongoing investigations to determine the source and potential migration path of the tritium, an increased environmental sampling program was initiated. On June 13, 2007, tritium levels in excess of Nuclear Energy Institute (NEI) voluntary reporting criteria were confirmed to be present in new onsite shallow groundwater wells. Immediate corrective actions taken were to perform additional sampling of areas surrounding the stabilization pond and (to reconfigure) the Turbine Building air-wash system. The reconfiguration of the turbine building airwash system will be done to eliminate the designed pathway of water to the storm drain collection basin and to the storm drain stabilization pond. Additional corrective actions include installation of additional monitoring wells at various locations to determine groundwater flow and checking for the presence of tritium. There is no indication that tritium has migrated into drinking water sources and all offsite monitoring has resulted in non-detectable levels of tritium. It is believed that the likely source of the tritiated water is seepage from the SDSP. The following agencies will be updated on the status of the onsite tritium samples and informed of the pending press release: State Officials, City of Southport, Brunswick County, NEI, INPO, and ANI. The Licensee notified the NRC Resident inspector. | ||
| ENS 40958 | 15 August 2004 17:22:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Made Due to Inadvertent Emergency Siren Actuation | On August 15, 2004, at approximately 1322 hours, the Brunswick site identified an inadvertent actuation of 1 offsite evacuation siren.
