The renewed licences authorise reactor operation from 60 to 80 years.
The NRC approved initial licence renewals of 20 years for both units in May 2003, with Unit 2 licensed to operate until 8 August 2033 and Unit 3 until 2 July 2034. Those dates have now been extended by 20 years. The new Peach Bottom-2 subsequent licence expires on 8 August 2053 and the Peach Bottom-3 licence on 2 July, 2054.
Both units are 1,308-MW boiling water reactors. Peach Bottom-2 began commercial operation in July 1974 and Peach Bottom-3 in December 1974.
Peach Bottom has a third unit, Unit 1, a 40-MW high temperature, gas-cooled reactor which was permanently shut down in November 1974.
Exelon submitted the licence renewal application on July 10, 2018. The company said in a statement on 6 March that it had made significant investments in new equipment and technologies to increase Peach Bottom’s generation capacity by approximately 12%. Many of Peach Bottom’s major components, including the station’s high and low-pressure turbines, steam dryers, main generators and main power transformers have been replaced or upgraded.
