The plant temporarily shut down in 1978 when PGE realized it had been built on an earthquake fault. It was shut down again when cracks in the steam tubes were detected just four years into the plant's life.
http://seattletimes.nwsource.com/html/localnews/2003004692_trojan19m.htmlEnvironmental opposition dogged Trojan all of its life, including violent clashes both inside and outside the boundary fence. In an Oregon state poll in 1980, a proposal to ban construction of further nuclear power plants in the state was approved by voters. Then in 1986, a proposal by Lloyd Marbet for immediate closure of the Trojan plant was defeated. This proposal was resubmitted in 1990, and again in 1992 when a competing proposal by Jerry and Marilyn Wilson to close the plant was also included. Although all of these closure proposals were defeated, in campaigning against them the plant operators committed to successively earlier closure dates for the plant.
In 1992, PGE spent over $5 million to defeat a statewide ballot measure to close Trojan in what is still the most expensive ballot measure campaign in Oregon history. Then, within a week, the Trojan plant suffered yet another steam generator tube leak of radioactive water and was shut down. In December 1992, documents leaked from the U.S. Nuclear Regulatory Commission, showing that staff scientists believed that Trojan may be unsafe to operate. In January 1993, PGE announced it would not try to restart Trojan.

As of 2005 the reactor vessel and other radioactive equipment has been removed from the Trojan plant. The reactor vessel was transported intact by barge along the Columbia River to Hanford Nuclear Reservation in Washington where it was buried. The spent fuel is stored onsite in 34 dry casks, awaiting transport to Yucca Mountain Repository.
http://www.trojandown.com/history.htmThese radioactive fuel rods were supposed to be moved to a federal nuclear waste repository for reprocessing and safe storage. But the promised federal repository never materialized. The official repository under Yucca Mountain in Nevada hasn’t opened because of public opposition. So spent radioactive fuel rods have accumulated at every nuclear power plant in the country, stored in basins of water, from the time each plant began producing electricity. At Trojan, there are 17 years of spent fuel rods, accumulated in a glorified swimming pool, on the flood plain of the lower Columbia River, sitting on an earthquake fault with no serious plans to move them in the foreseeable future.
