Trojan Nuclear Power Plant
1976 - 1993
Trojan Nuclear Power Plant
The plant took its name from the Trojan Powder Company, the dynamite, and explosives storage facility on the site during World Wars I and II. PGE chose the site in 1967, and construction began on Feb. 1, 1970. The plant was connected to the grid in December 1975 and commercial operation began on May 20, 1976, under a 35-year license to expire in 2011. At the time, the single 1,130-megawatt unit was the world's largest pressurized water reactor. It cost $460 million to build.
In 1978, following the discovery of an unknown fault, the plant went offline for routine refueling and remained offline for nine months while modifications were made to improve its resistance to earthquakes.
