Installation of BWR Drywell – Nine Mile Point

Author: No Comments Share:

Nine Mile Point Nuclear Station is a two-unit nuclear power plant located in the Town of Scriba, approximately five miles northeast of Oswego, New York, on the shore of Lake Ontario. The 900 acre (3.6 km²) site is also occupied by the Fitzpatrick Nuclear Generating Station.

Nine Mile Point is operated by Constellation Energy Group. Constellation is also the sole owner of Unit 1, and owns 82% of Unit 2 (Long Island Power Authority owns the remaining 18%).

Units 1 and 2

Both units are General Electric boiling water reactors. Unit 1, a BWR-2, went online in 1969 and has a rated capacity of 609 MW. It is one of the two oldest nuclear reactors still in service in the United States; New Jersey‘s Oyster Creek Nuclear Generating Station is the other. Unit 2, a BWR-5, has been in operation since 1988 and has a rated capacity of 1,148 MW. Construction of both units, along with neighboring Fitzpatrick, was commissioned by Niagara Mohawk Power Corporation. Fitzpatrick was sold immediately upon completion, while Niagara Mohawk retained its share of the Nine Mile Point units until 2001, when it sold them to Constellation.

On October 31, 2006, Constellation announced that the NRC had granted 20-year license extensions to both units. Unit 1 is now licensed to operate until 2029 and Unit 2 is licensed until 2046.

The Nine Mile Point cooling tower is visible from Chimney Bluffs in Sodus, New York nearly 30 miles away.

In early May 2011, the operator of the plant reported that its fuel supplier, General Electric, notified it that mathematical errors were made which could resulted in reactor fuel’s getting hotter than operator thought.
