However, by the time the leak was found and isolated, approximately 1,050 gallons of water containing low levels of tritium and trace amounts of other radionuclides had leaked into the yard drain system. Heavy rain at that time carried the slightly contaminated water to Niantic Bay. A berm, which was constructed around the WTT about a month ago, failed to contain the leak. The 21,000 gallon WTT is located outside of the waste disposal building on the Northwest side of the Unit 3 yard. A total of 0.0217 curies of radionuclides (predominately tritium) eventually reached Niantic Bay. This amount represents a whole body dose of 2.2E-07 millirem to the maximum exposed member of the public. Later that day, the remaining contents of the tank (over 15,000 gallons) were released to Niantic Bay through the normal release path. The licensee is investigating why the berm did not contain the leak, and is preparing to line the berm with an impermeable membrane. Regional Action: The resident inspectors are following the licensee's actions.
