Leaky valve spurs Pilgrim shutdown
No safety threat to public, workers, NRC official says
The Pilgrim Nuclear Power Station in Plymouth was shut down early yesterday morning because of a leak detected in one of four safety relief valve systems. The leak posed no threat to the public or to plant workers, according to a spokesman for the Nuclear Regulatory Commission. The leak occurred in a small valve that triggers a larger safety valve to open to relieve pressure. There are four such safety valves that are used in the case of pressure buildup, to vent steam from the reactor to the “suppression pool,” a donut-shaped reservoir of water at the bottom of the reactor building.
