The 499-foot cooling tower at the Trojan Nuclear Plant in Rainier, Oregon is imploded on May 21, 2006.  Portland General Electric's facility located 42 miles North of Portland on the Columbia River is the first large-scale commercial nuclear plant to be decommissioned in the United States.  The implosion of the 41,000 tons of concrete and steel took only 10 seconds and 2,800 pounds of dynamite.  The tower provided water cooling for electricity production in the region from 1976-1993.
