Title	Storm Drain System Tested Positive for Tritium
Event Description	On 4/06/10, Salem management was notified that samples taken from the Salem Unit 2 north storm drain system were positive for tritium. Two storm drain catch basin sample results were confirmed above 1 million pico Curies per liter. The affected area of the north storm drain system has been isolated. Samples upstream of the river outfall were less than the minimum detectable level for tritium. NRC reporting criteria were reviewed and, although no direct reportable criteria were met, based on the public sensitivity to tritium issues, it was determined that a voluntary notification to the NRC was prudent. Salem is taking action to mitigate, locate, and remediate the source of the tritium. In addition to isolating the affected portion of the system, the station has increased the sample frequency for the storm drain system and ground water wells in the affected area. A voluntary notification has been made to the appropriate State agency and the NRC Resident Inspector. * * UPDATE FROM TOM BYYKKONEN TO PETE SNYDER ON 4/8/10 AT 2025 * * * Based on further evaluation, Salem officially notified the New Jersey Department of Environmental Protection of the above tritium spill on 4/8/10 at 2003. This notification to New Jersey is reportable in accordance with 10 CFR 50.72(b)(2)(xi). The licensee notified the NRC Resident Inspector. Notified R1DO (Trapp).
