A lot (most?) of them are. Trojan, in Portland Oregon, wasn't. It left a bitter taste in the mouths of many Oregonians, especially the main population center of the state in Portland, to the point the basically banned it. Also a lot of Washingtonians were not happy that the leftover nuclear waste was buried up in their state as well as increased radioactive levels in the Columbia River detected since then, and higher than average deformation of fish. It was on the ballot year after year to get it closed down and finally leaked docs from the US NRC sealed the deal. I got to watch them blow it up! :) > After 16 years of irregular service, the plant was closed permanently in 1992 by its operator, Portland General Electric (PGE),[3] after cracks were discovered in the steam-generator tubing. Decommissioning and demolition of the plant began the following year and was largely completed in 2006 > 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.[citation needed] In October 1979, the plant was shut down through the end of the year for repairs.[14][15][16] The plant had an extended shutdown in 1984, with difficulty restarting. > 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.[26] In early January 1993, PGE chief executive Ken Harrison announced the company would not try to restart Trojan > 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 pit and covered with 45 feet (14 m) of gravel, which made it the first commercial reactor to be moved and buried whole.[31] It was awaiting transport to the Yucca Mountain Repository until that project was canceled in 2009. https://en.wikipedia.org/wiki/Trojan_Nuclear_Power_Plant https://en.wikipedia.org/wiki/Trojan_Nuclear_Power_Plant
