08/20/2013  A safety problem the NRC ordered fixed in 1979 remained unfixed until 2013, as described in Fission Stories #144.

12/04/2012  Fission Stories #120 cited the 18 safety problems reported by the owner to the NRC since the plant was shut down in 2011 and observed that most of these problems had existed for many years. Why are workers unable to find safety problems when reactors are operating?

04/06/2012  An All Things Nuclear blog post marked the first anniversary of the reactor’s shut down to enter a scheduled refueling outage. The schedule went out the window as first the Missouri River overflowed its banks temporarily making the plant an island and then a flood of safety problems prevented the reactor from restarting once the waters receded.

06/07/2011  Fission Stories #110 described how an improperly replaced electrical breaker initiated a fire that, among other things, interrupted the system cooling the spent fuel pool.

02/17/2010  Pumps in an emergency water makeup system failed repeatedly over several years. The plant owner never identified the true cause of the failures, and therefore did not take the right steps to prevent their occurrence.
