For the second time in less than a week, the Nine Mile Point Unit 2 nuclear power plant in Oswego County experienced an automatic shutdown, due to a problem at the plant.
The shutdown happened around 4:30 p.m. Monday. According to a spokesperson from Constellation Energy, which owns the plant, a worker "inadvertently contacted a highly sensitive plant component." As a result, safety systems shut down the plant automatically.
Nine Mile Point 2 was shut down early this morning after losing power from a supply unit in the plant.
Neil Sheehan, a public affairs officer for the Nuclear Regulatory Commission, said the loss of power effected cooling flow to both of the plant's reactor recirculation pumps.
"The operators at the plant, in turn, manually scrammed or shut down the reactor," Sheehan said. "And that means they inserted all the control rods, halted the fissioning process and, therefore, the plant was no longer heating up water and generating electricity."
The U.S. Nuclear Regulatory Commission (NRC) has issued a citation to the owners of the Ginna nuclear power plant in upstate New York. Preliminary inspection findings released Tuesday cited the plant for failure to address a long-standing flood risk. The issue is considered a low-to-moderate level safety concern.
It all comes down to an improperly sealed manhole at the plant, which could have allowed flood waters to breach the rooms housing emergency batteries.
