The reactor at the Pilgrim Nuclear Power Plant was shut down this morning.
Around 7:50 a.m., plant operators took action after two of the three main feedwater pumps tripped, shutting them down. The plant’s feedwater pumps send water into the reactor vessel, which converts the water to steam and then is piped to the turbine to generate electricity.
Initial troubleshooting showed ho problem with the cooling water flow, but instead, a problem with the electrical power for the system that monitors the flow.
According to the NRC, the plant is in a safe condition and that operators have taken appropriate actions in response to the problem.
Resident NRC inspectors are on site monitoring the situation.
