In separate incidents, two reactors, one in Massachusetts and one in Georgia, shut down over the weekend.
Due to high reactor water level, Pilgrim Nuclear Power Station in Plymouth, MA, powered down Saturday afternoon.
“The cause of the increase in reactor water levels is currently under investigation,” plant owner Entergy said a report to the Nuclear Regulatory Commission (NRC). The plant had been in start-up mode after a forced shutdown related to problems with NSTAR’s power lines, which delivers both in and out of the plant.
Entergy officials wrote this latest event has no impact on public health and safety. Since mid-August, the 41-year-old plant has been plagued by problems forcing shutdowns or lower than peak levels of output due to mechanical glitches.
Meanwhile, one of Plant Vogtle’s reactors shut down over the weekend in Waynesboro, GA.
According to a NRC spokesperson, the reactor was operating at full power, when the Unit 2 turbine tripped and caused the reactor to automatically shut down for safety reasons.
The reactor is in the process of going back online now, and the spokesperson said there was no danger to the public.
