Re: OC-Potential Tritium Release on 4/15 72
- Marc, Ron called me about this last evening. I would want to know if this find meets the NEI reportability criteria and if so, how-'
Exelon plans to make this information public. I also would want to know ASAP how the water may have gotten in the vaul, and what the company intends to do to check on extent of condition. Also, any word on whether N.J. plans to make an announcement or post something pn its web site about this.

OC-Potential Tritium Release on 4/15 As of 8 pm on April 15, 2009.
ISSUE
SUMMARY
On April 15, 2009, Oyster Creek identified water containing tritium inside the Emergency Service Water (ESW) cable vault which is located in the vicinity of the intake structure. Chemistry samples of the water revealed tritium levels of 102,000 pCi/L. Exelon reported to the New Jersey Department of Environmental Protection (DEP) of a potential release of tritium to soil to; and completed a 4-hr ENS notification to the NRC for a notification to another government agency.
BACKGROUND On April 13, Oyster Creek began maintenance activities which involved replacement of 4160V electrical cable for the '1-2' ESW pump. In preparation for the work inside the ESW cable vault, water found inside the vault was pumped into drums and sampled per station procedures. The water was sampled for gamma emitters, tritium, and pH. Chemistry samples on April 15 did not identify gamma emmitters, had a pH of 7.62, and a tritium concentration of 102,000 pCi/L. The amount of water in the vault and contained into drums is not known at this time. Exelon has stated to external stakeholders that no release is known to be occurring and no release is known to have occurred; and that source of the Tritium water is not currently known.
Exelon's reporting criteria to the New Jersey DEP for tritium is 2,000 pCi/L and where notified on April 15 of the sample results and a potential release of tritium to the soil. It was also iterated to the DEP that the water was contained in a concrete vault and is being pumped into drums. Exelon, also completed a 50.72 4-hr report to the NRC via the ENS due to notification to another government agency.
Exelon has initiated a prompt investigation and are making preperations to get independent analysis of the samples performed.
Shortly after making notification to the DEP the control room received a call from local law enforcement (Lacey Township Police).
