Trojan Nuclear Power Plant was a pressurized water reactor nuclear power plant located southeast of Rainier, Oregon, United States, and the only commercial nuclear power plant to be built in Oregon. After sixteen years of service it was closed by its operator, Portland General Electric (PGE), almost twenty years before the end of its design lifetime. Decommissioning and demolition of the plant began in 1993 and was completed in 2006.
Construction of Trojan began February 1, 1970. First criticality was achieved on December 15, 1975, and grid connection on December 23, 1975. Commercial operation began on May 20, 1976, under a 35-year license to expire in 2011. The single 1130 megawatt unit at Trojan was then the largest pressurized water reactor built. It cost $450 million to build the plant.
Environmental opposition dogged Trojan from its inception, and the opposition included non-violent protests organized by the Trojan Decommissioning Alliance. The Alliance organized the first major direct action protest at Trojan in August 1977, and a second round of protests took place that November. Scores of demonstrators were arrested, and in December 1977 a jury found 96 protesters not guilty of criminal trespass. There was another protest in August 1978, which led to about 280 arrests.
In 1978, the plant was closed for nine months while modifications were made to improve its resistance to earthquakes. This followed the discovery of both major building construction errors and the close proximity of a previously unknown faultline. The operators sued the builders, and an undisclosed out-of-court settlement was eventually reached.
The Trojan steam generators were designed to last the life of the plant, but it was only four years before premature cracking of the steam tubes was observed.
In the 1980 Oregon election, a ballot measure to ban construction of further nuclear power plants in the state without federally approved waste facilities was approved by the voters 608,412 (53.2%) to 535,049 (46.8%). In 1986, a ballot measure initiated by Lloyd Marbet for immediate closure of the Trojan plant was failed 35.7% yes to 64.3% no. This proposal was resubmitted in 1990, and again in 1992 when a similar proposal (by Jerry and Marilyn Wilson) to close the plant was also included. Each measure was soundly defeated by vote margins over 210,000 votes. Although all closure proposals were defeated, the plant operators committed to successively earlier closure dates for the plant.
In 1992, Portland General Electric (PGE) spent $4.5 million to defeat ballot measures seeking to close Trojan. It was the most expensive ballot measure campaign in Oregon history until the tobacco industry spent $12 million in 2007 to defeat Measure 50. A week later the Trojan plant suffered another steam generator tube leak of radioactive water, and was shut down. It was announced that replacement of the steam generators would be necessary. In December 1992, documents were leaked from the U.S. Nuclear Regulatory Commission showing that staff scientists believed that Trojan might be unsafe to operate. In January 1993, chief plant engineer David Fancher, acting as spokesman for PGE, announced the company would not try to restart Trojan.
The spent fuel was transferred from cooling pools to 34 concrete and steel storage casks in 2003.
In 2005, the reactor vessel and other radioactive equipment were removed from the Trojan plant, encased in concrete foam, shrink-wrapped, and transported intact by barge along the Columbia River to Hanford Nuclear Reservation in Washington, where it was buried in a 45-foot-deep (14 m) pit and covered with 45 ft of gravel, which made it the first commercial reactor to be moved and buried whole. The spent fuel is stored onsite in 34 dry casks. It was awaiting transport to the Yucca Mountain Repository until that project was canceled in 2009.
The iconic 499-foot-tall (152 m) cooling tower, visible from Interstate 5 in Washington and U.S. Route 30 in Oregon, was demolished via dynamite implosion at 7:00 a.m. on May 21, 2006. This event marked the first implosion of a cooling tower at a nuclear plant in the United States. Additional demolition work on the remaining structures continued through 2008. The central office building and the reactor building were demolished by Northwest Demolition and Dismantling in 2008. Remaining are five buildings: two warehouses, a small building on the river side, a guard shack, and offices outside the secured facility. It is expected that demolition of the plant will cost approximately $230,000,000. This cost includes the termination of the plant possession-only license, conventional demolition of the building and continuing cost for storage of used nuclear fuel.
