| ENS 50725 | 8 January 2015 22:26:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to Low Level Tritium Spill | On January 7, 2015, at approximately 0700 CST, a leak to the environment was identified. Tritium was present at a concentration of 7.52E-3 uCi/mL, which is above the US Environmental Protection Agency (EPA) drinking water standard of 20,000 picocuries per liter. No other radioactive isotopes were identified. The leak rate was estimated at approximately 0.5 gpm and determined to be from the condensate head tank. Water was accumulating on the concrete-lined reactor/refuel air zone air intake plenum with some accumulation of water on the ground in the area. The intake plenum contains three floor drains. Actions were immediately taken to terminate the leak once the flowpath was identified. The flowpath was terminated two hours and 45 minutes after identification. Based on system review and analysis, any tritiated water that would have made it to the floor drains would then be mixed with incoming raw water at two million gallons per minute. This mixed volume of water would then be circulated through the plant and discharged to the river with a resultant tritium concentration that is much less than detectable levels and well below US EPA drinking water standards. The station has established increased monitoring of groundwater at designated sample wells. On January 8, 2015, at approximately 1645 CST in accordance with TVA procedures and the guidance of NEI 07-07 (Nuclear Energy Institute) for the Groundwater Protection Initiative, the licensee notified the Alabama Radiological Protection Department and Alabama Department of Environmental Management.

| ENS 46179 | 16 August 2010 18:40:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Npdes Limit Was Exceeded for River Temperature Discharge Requirements | Browns Ferry Nuclear Plant inadvertently exceeded a limitation of its National Pollutant Discharge Elimination System (NPDES) Permit for Tennessee River temperature conditions which was reported to the Alabama Department of Environmental Management (ADEM) at 1340 Central Daylight Time, on August 16, 2010. As such, this is being reported in accordance with 10 CFR 50.72(b)(2)(xi) as 'Any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made.' The NPDES Permit requires that when the 24 hour ambient average river temperature exceeded 90 degrees Fahrenheit, the 24 hour average downstream river temperature may equal but not exceed the upstream value. The 24 hour average upstream temperature was found to be 90.4 (rounded to 90) degrees Fahrenheit and the downstream temperature was found to be 90.6 (rounded to 91) degrees Fahrenheit. Browns Ferry had been maintaining compliance with the NPDES permit. The departure is thought to be due to a summer storm cooling off the upstream temperature. With the time delay between upstream temperature changes and the ensuing rate at which the downstream temperature changes are observed, the resultant 24 hour average downstream river temperature exceeded the upstream value. Duration of this condition was found to be only several hours. The three Browns Ferry units, which had already been derated to approximately 50 percent rated thermal power in order to maintain compliance with the NPDES Permit river temperature limits, were further derated to achieve compliance with the NPDES Permit. There is no corresponding requirement for written follow-up in accordance with 10 CFR 50.73. The licensee has notified the NRC Resident Inspector. | ||

| ENS 43891 | 10 January 2008 18:21:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification - Spill of Water Containing Tritium | This is a voluntary notification for a spill of water containing tritium as specified in section 2.2.a.iii, of Nuclear Energy Institute document NEI 07- 07 entitled 'Industry Groundwater Protection Initiative.' On January 5, 2008 at 13:55, Browns Ferry Nuclear (BFN) Plant operations personnel received a high water level alarm on a sump located within the plant, at the Condensate Piping Tunnel. The high water level was corrected within 3 hours of the alarm. Investigation into this condition determined that the water came from an overflow of the Unit 3 Condensate Storage Tank into the tunnel as a result of failed tank level instrumentation. The water was immediately transferred to the plant radioactive waste system for processing. Laboratory analysis results received on January 9, 2008 indicated this water contained 2.2 E-03 uCi/ml tritium. Based on the tunnel construction, there is a potential for a small amount of this water to permeate into the ground. Subsequent to the spill, a sample obtained from the ground water sampling well adjacent to the tunnel showed no detectable level of tritium. BFN routinely monitors the ground water for radioactivity in accordance with the NEI Groundwater Protection Initiative. Tritium levels at BFN have never reached or exceeded the Environmental Protection Agency drinking water limit. This spill was contained within the plant structure and will not increase the dose to the public. As such, this event poses no threat to public health or safety.
