Why is Pilgrim at 12% Power

Entergy's Pilgrim nuclear power plant is shut as snowstorm envelops Massachusetts

Washington (Platts)--8 Feb 2016 453 pm EST/2153 GMT

Operators at Entergy's 728-MW Pilgrim nuclear plant in Plymouth, Massachusetts, shut the unit early Monday morning as a precautionary measure, while a snowstorm swept through the state, a plant spokesman said.

Pilgrim spokesman Patrick O'Brien said operators began to reduce the unit's power from 100% at 9 pm EST (0200 GMT) Sunday, noting the "weather might be an issue, with loss of power" possible. Pilgrim shut automatically in January 2015 and in February 2014 during snowstorms when offsite power, provided by a local utility, was interrupted.

The unit was operating at 12% of capacity just prior to being shut, according to the US Nuclear Regulatory Commission's daily reactor status report Monday.

O'Brien declined to estimate when Pilgrim will restart and return to 100% capacity, saying this information "is market sensitive."

Maybe a SRV is leaking?

The Pilgrim guys say its because of the blizzard...
