Trojan Nuclear Power Plant was a pressurized water reactor nuclear power plant in the northwest United States, located southeast of Rainier, Oregon, and the only commercial nuclear power plant to be built in Oregon. There was public opposition to the plant from the design stage. The three main opposition groups were the Trojan Decommissioning Alliance, Forelaws on the Board, and Mothers for Peace. There were largely non-violent protests from 1977, and subsequent arrests of participants.
After sixteen years of service the plant was closed by its operator, Portland General Electric (PGE), after cracks were discovered in the steam-generator tubing. Decommissioning and demolition of the plant began in 1993 and was completed in 2006.
While operating, Trojan represented more than 12% of the electrical generation capacity of Oregon. The site lies about twelve miles north of St. Helens, Oregon, on the banks of the Columbia River.
Construction of Trojan Nuclear Power Plant 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 $460 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. Direct action protests were held at the plant in 1977 and 1978, resulting in hundreds of arrests.
