New Jersey’s Oyster Creek Nuclear Generating Station remains under an official Alert, a day-and-a-half after the US Nuclear Regulatory Commission declared the emergency classification due to flooding triggered by Hurricane Sandy. An Alert is the second category on the NRC’s four-point emergency scale. Neil Sheehan, a spokesman for the federal regulator, said that floodwaters around the plant’s water intake structure had receded to 5.7 feet at 2:15 PM EDT Tuesday, down from a high of 7.4 feet reached just after midnight.

If hoses desperately pouring water on endangered spent fuel pools remind you of Fukushima, it should. Oyster Creek is the same model of GE boiling water reactor that failed so catastrophically in Japan.

For those who thought that, with the new year, nuclear power had turned a page and put its “annus horribilis” behind it–as if the calendar were somehow the friend America’s aging reactors–let’s take a quick look at January 2012.

In what feels like a Friday news dump that goes to 11, the US Nuclear Regulatory Commission has given its approval to restart Dominion Virginia Power’s North Anna nuclear power facility. The decision came late in the day on a holiday–Veterans Day, 11/11/11.

As September drew to a close, residents of southwest Michigan found themselves taking in a little extra tritium, thanks to their daily habit of breathing. The tritium was courtesy of the 40-year-old Palisades Nuclear Generating Station in Covert Township, which suffered its third “event” (as they are politely called) in less than two months, and was forced to vent an indeterminate amount of radioactive steam.
The reactor at Palisades was forced to scram after an accident caused an electrical arc in a transformer in the DC system that powers “indications and controls“–also known as monitoring devices, meters and safety valves.
While it is nice to see rectors shut themselves down when a vital system goes offline, remember that “turning off” a fission reactor is not like flicking a light switch. Shutting down a reactor is a process, and the faster it is done, the more strain it puts on the reactor and its safety and cooling systems. And even after fission is mitigated, a reactor core generates heat that requires a fully functional cooling system.
