Ginna Nuclear Generating Station
From Wikipedia, the free encyclopedia
Robert E. Ginna nuclear power plant is near Rochester, New York, in the United States. It is a single unit Westinghouse 2-Loop pressurized water reactor, similar to those at Point Beach, Kewaunee, and Prairie Island.
The Ginna plant was the site of a small nuclear accident when, on January 26, 1982, a small amount of radioactive steam leaked into the air after a steam-generator tube ruptured. The leak which lasted 93 minutes led to the declaration of a site emergency. The rupture was caused by a small pie-pan-shaped object left in the steam generator during an outage. This was not the first time a tube rupture had occurred at an American reactor but following on so closely behind the TMI Incident caused considerable attention to be focused on the incident.
In 1996 the original Westinghouse suppled steam generators (including the one that was damaged in 1982 and repaired) were replaced by two brand new Babcock and Wilcox steam generators. This project enabled an uprating of Ginna's output several years later and was a major factor in the approval of the plant's operating license extension for 20 years beyond the current license valid until 2009.
In 2004, Constellation Energy Group acquired Ginna from Rochester Gas and Electric.
Ginna is one of the oldest nuclear power reactors still in operation in the United States: it went into commercial operation in 1970.
