| Event Description | At 1314 hours0.0152 days <br />0.365 hours <br />0.00217 weeks <br />4.99977e-4 months <br /> on Wednesday, April 10, 2013 during a boroscopic inspection of the sub-surface portions of the Neutralizing Sump Discharge Line, Pilgrim Station discovered indications of a separation in the line. The line is currently isolated and no discharges were in progress during the planned inspection. This line is used infrequently to discharge permitted liquids that have the potential to contain radiological contamination. This
notification is conservatively being made in accordance with Pilgrim site procedures with direct voluntary communications with offsite agencies. There is no impact on the safe operation of the plant and personnel are investigating the cause. The [NRC] Resident Inspector staff has been informed of this notification. This notification is being made in accordance with 10 CFR 50.72(b)(2)(xi). The licensee will notify the Massachusetts Emergency Management Agency (MEMA) and other state agencies.
Entergy Pilgrim Station has twenty three (23) groundwater monitoring wells used to sample for tritium and other radioactive nuclides in accordance with the Nuclear Energy Institute's (NEI) voluntary Groundwater Protection Initiative (GPI). One of the newly installed wells, MW-219, located in the vicinity of a Catch Basin adjacent to the Reactor Building Auxiliary Bay and in the flow path of the Neutralizing Sump Discharge Line indicated an elevated level of tritium (H3), that exceed the limits established by the NEI Groundwater Protection initiative and the Nuclear Regulatory Commission's (NRC) limits for liquid effluent release. A protocol for more frequent sampling has been instituted and an investigation of the cause is underway. To date, tritium is the only isotope detected In the groundwater monitoring well samples collected at the site. This supplemental information has been voluntarily communicated to Federal, State and local stakeholders. The NRC Resident Inspector has been notified of this update. This is an update to the 4-hour non-emergency notification made in accordance with 50.72(b)(2)(xi) on April 10, 2013 at 1619 hours0.0187 days <br />0.45 hours <br />0.00268 weeks <br />6.160295e-4 months <br />.
