The owners of the defunct Trojan nuclear power plant in Oregon, which many locals believe was the inspiration for the accident-prone nuclear plant on “The Simpsons,” want to make the area into a state park. Portland General Electric is offering the land for free, hoping to show that a decommissioned nuclear plant can be safe. In addition to a 500-foot cooling tower and a fortified tank of spent radioactive fuel, the area has nearly 500 acres of woods and wetlands, a number of lakes and creeks, access to the Columbia River, and some 200 species of wildlife. State officials aren’t yet convinced that a park is a good idea. “We’d never need electricity at night because the place glows,” joked state parks spokesperson Jim Lockwood.
