Southwest Michigan’s Herald-Palladium reported this afternoon:
The Palisades nuclear power plant was shut down Friday afternoon after a water leak of more than 10 gallons per minute was detected in the system that cools the plant’s nuclear reactor.
The plant was shut down shortly before 3 p.m. because the leak exceeded the plant’s technical specifications, spokesman Mark Savage said. The plant filed a notification of an “unusual event” with the federal Nuclear Regulatory Commission.
The likely cause of the problem is a leak on a valve in the primary cooling system, but that won’t be known for certain until workers can get in and do a thorough evaluation, Savage said.
There is no estimate for when the plant will be back in operation, Savage said Friday afternoon.
There probably won’t be a lot more information about this incident until the NRC Event Reports post on Monday morning. I’ll let you know if there are additional details then.
Palisades nuclear is located about a hundred miles east of Chicago, across Lake Michigan.
