4OA3 Follow-up of Events
Event Notification 50751: Notice of Unusual Event (NOUE) Declared Due to Toxic Gas in the Security Diesel Building
a. Inspection Scope
For the plant event listed below, the inspectors reviewed plant parameters, reviewed personnel performance, and evaluated performance of mitigating systems. The inspectors communicated the plant events to appropriate regional NRC personnel, and compared the event details with criteria contained in IMC 0309, issued October 28, 2011, "Reactive Inspection Decision Basis for Reactors," for consideration of potential reactive inspection activities. As applicable, the inspectors verified that the licensee made appropriate emergency classification assessments and properly reported the event in accordance with 10 CFR 50.72. The inspectors reviewed the licensee's follow-up actions related to the events to assure that the licensee implemented appropriate corrective actions commensurate with their safety significance. This constitutes one sample. Documents reviewed are listed in the Attachment.
- On January 22, 2015, operations personnel declared a NOUE for Units 1 and 2 in accordance with Emergency Action Level HU 3.1, toxic, corrosive, asphyxiate, flammable gas release that could affect normal operations, due to smoke in the Security Diesel Uninterruptible Power Supply (UPS) Room. Fire alarms were received in the building, smoke was reported coming from the building, the fire protection Novec system discharged, and the fire brigade responded to the building.
No other plant equipment was effected. The licensee determined the cause to be a faulty filtering capacitor in the UPS cabinet. The UPS capacitors were replaced, and there are no other similar capacitors onsite. The licensee wrote NCRs 728951 and 728953 to address this event.
b. Findings
No findings were identified.
4OA5 Other Activities
On March 17, 2015, the inspectors held a teleconference with licensee staff and a State of North Carolina radiation protection representative to discuss the status of the groundwater monitoring program. The licensee provided an update on tritium concentrations in water collected from onsite and offsite groundwater and surface water sampling locations and discussed ongoing remediation efforts associated with the storm drain stabilization pond and areas near a Unit 1 condensate storage tank underground pipe leak. The licensee has installed a network of sub-surface pumping wells that continuously removes water from the affected areas; thereby reducing the overall tritium concentration in groundwater and limiting plume migration. Publicly available information regarding onsite groundwater monitoring and radionuclide concentrations in the environment near Brunswick Steam Electric Plant can be found in the Annual Radiological Environmental Operating Report. Recently issued reports can be found on
the NRC's public website: http://www.nrc.gov/reactors/operating/ops-experience/tritium/plant-specific-reports/bru1-2.html.
