Last summer, a leaky tank led to the shutdown of the Palisades nuclear power plant in Michigan. So plant owner Entergy patched up the leak, fired back up the reactor, and hoped for the best.
Unfortunately, the best did not materialize.
The tank began leaking again. But no worries, thought the Einsteins at Entergy, it was only leaking a gallon a day. That was OK, they figured, because the NRC had allowed it to leak up to 38 gallons a day. As of Friday, they were still doing that whole "hoping for the best" thing.
But on Saturday the leaky drip turned into a gush, and all the hoping in the world couldn't hold back the tide of spilling radioactive water. Nearly 80 gallons of water containing small amounts of radioactive tritium and possibly trace amounts of cobalt and cesium spewed into Lake Michigan, the Nuclear Regulatory Commission told the AP.
