MASSACHUSETTS AGENCIES NOTIFIED REGARDING NEUTRALIZING SUMP DISCHARGE LINE INSPECTION

"At 1314 hours 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."

* * * UPDATE AT 1700 EST ON 01/15/14 FROM STAN PAUL TO S. SANDIN * * *

"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 hours."

Notified R1DO (Rogge).

FISH LOSS AT CLINTON POWER STATION

"The following report is being made in accordance with Clinton Power Station Operating License, Appendix B, Environmental Protection Plan.

"On 1/14/14, an inspection of the Clinton Lake was conducted via boat of inaccessible areas. The inspection revealed more than one hundred deceased fish over several locations. The species predominantly observed were buffalo fish and carp, with some game fish identified. While no direct cause was identified for the fish loss, the fish loss closely coincides with two recent unplanned plant shutdowns that occurred in December 2013."

The licensee informed the State and the NRC Resident Inspector.

DRYWELL RADIATION MONITOR INOPERABLE

"At 0723 [CST] hours on January 15, 2014, the 2A Drywell Radiation Monitor was declared inoperable after exhibiting erratic performance. This monitor provides the input into one division of the primary containment isolation logic for a Group II isolation. As a result, the channel was placed in a tripped condition in accordance with Technical Specification 3.3.6.1, Condition B.

"Given both divisions are required to complete the Group II isolation logic, this condition is reportable in accordance with 10 CFR 50.72(b)(3)(v)(C) as an event or condition that could have prevented the fulfillment of a safety function.

"The 2A Drywell Radiation Monitor has been repaired and restored to an operable condition.

"The NRC Resident Inspector has been notified."

LOSS OF SECONDARY CONTAINMENT DIFFERENTIAL PRESSURE

"Reactor Building (Secondary Containment) pressure increased to above the Technical Specification Surveillance requirement of 0.25 inches vacuum water gauge briefly (5 minutes or less). This is reportable as an event that could have prevented fulfillment of a safety function needed to control the release of radiation and mitigate the consequences of an accident. Reactor Building pressure has been restored to normal (greater than 0.25 inches vacuum water gauge), returning Secondary Containment to operable status. Highest actual value was 0.21 inches vacuum water gauge.

"There were no radiological releases associated with the event."

The differential pressure change is believed to have been caused by a momentary shift in Heating and Ventilation Systems dampers.

The licensee has notified the NRC Resident Inspector.
