California’s troubled San Onofre nuclear plant is shutting down for good. San Onofre has been idle for over a year following a radioactive leak. The leak led to the discovery of excessive wear in tubing that carries radioactive water. The plant’s operator, Southern California Edison, had maintained it wanted to restart the reactors but on Friday announced the plant would be permanently closed. In a statement, the environmentalist group Friends of the Earth welcomed the news, saying: “The people of California now have the opportunity to move away from the failed promise of dirty and dangerous nuclear power and replace it with the safe and clean energy provided by the sun and the wind.”
