10/21/2008  Fission Stories #24 describes the wrong kind of chain reaction at a nuclear plant – workers accidentally damaged a water supply pipe whose leakage triggered the fire protection deluge system whose water flooded a ventilation system whose leakage shorted out an electrical relay that opened a safety relief valve that prompted the operators to shut down the reactor.

12/28/1994  Fission Stories #64 explained how a bolt dropped into the spent fuel pool created a path for 2,000 gallons of slightly radioactive water to leak out. (Okay, it was a nuclear-sized bolt nearly 17-feet long and weighing 365 pounds).

12/02/1986  Fission Stories #42 explains how 141,000 gallons of water drained from the spent fuel pool after a worker mistakenly stopped the flow of air to the inflatable seals around the fuel pool’s gate.

12/21/1985  Fission Stories #114 explained how a valve that had been disassembled for maintenance allowed a room containing emergency pumps to be flooded with 14 feet of water during a test.
