08/19/2009  Seven hours after the reactor shut down automatically because of a problem with the electrical grid, an NRC inspector found water leaking from the system that cools the emergency diesel generators and virtually all other emergency equipment. An internal study in 2007 had forecast such leakage, and a leak had actually occurred after a reactor shutdown in April 2008. However, the owner had taken few steps to correct this serious safety problem.

1/30/1996   Fission Stories #52 described an event where ice freezing on the surface of the lake used by the plant for its cooling water blocked that vital in-flow.

12/1987   Fission Stories #112 described how a valve mistakenly left open allowed water from the spent fuel pool to drain to a water storage tank over the next two days.
