Exelon announced that Unit 1 at the Limerick nuclear power plant was shut down earlier today after losing power to the main generator cooling pumps. There are not a lot of additional details available at this hour, and most of the press coverage so far consists of rewrites of the Exelon press release.
One thing not mentioned is how lucky Exelon was that the incident did not occur earlier in the week. The Nuclear Regulatory Agency conducted the plant’s annual performance review yesterday.
