US NRC Blog Update: The Relative Calm After the Storm

The Relative Calm After the Storm by Moderator Credit: NASA/NOAA There’s a feeling of normalcy in the NRC’s Region I today. After days of tracking Sandy and assuring the nuclear power plants in the Northeastern U.S. were in a safe condition, the storm is now out of the area and we’re open and back to business as usual. Beginning last week – well in advance of the storm - nuclear power plant workers in the potential path of the storm took steps to prepare the site, such as tying down loose equipment, removing debris that could become projectiles, and topping off water and fuel tanks. NRC inspectors assured they took all of the appropriate steps. As Sandy made its way toward the coast, the agency stationed inspectors around the clock at all of the plants that could experience effects of the storm, and agency response experts monitored the storm from our emergency response centers, and tracked it as it traveled inland. While a number of plants reduced power or needed to shut down, all plants made it through the storm safely. Oyster Creek, which declared an Alert Monday night when a combination of a rising tide, wind direction and storm surge caused water level to rise in the intake structure, exited the Alert early Wednesday morning. The plant also regained off-site power, which it had lost during the storm. Three nuclear power plants shut down during the storm. Indian Point 3 and Nine Mile Point 1 due to grid disturbances, and Salem Unit 1 due to high water level and debris affecting the circulating water pumps. Preparations are underway at each of those sites to return them to service. The plants that reduced power, Millstone 3, Limerick Units 1 and 2, and Vermont Yankee are at or near full power today. The NRC and the nuclear plant operators worked hard to assure that the plants were safe over the weekend. In all, dozens of NRC staff members spent days preparing for and responding to the storm. While our thoughts are with those who have lost so much to the storm, we are satisfied that we did our jobs to respond quickly and effectively to the challenges the storm posed to the nuclear power plants we regulate.
