The US Nuclear Regulatory Commission staff has approved Exelon Generation Company’s application for an additional 20 years of operation for the Peach Bottom-2 and -3 nuclear power units in Pennsylvania.

The renewed licences authorise reactor operation from 60 to 80 years.

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.
