The US Nuclear Regulatory Commission (NRC) has awarded a 20-year licence renewal for the two commercial nuclear reactor units operating at the North Anna site in Virginia.
There are two Westinghouse-made 948-MW and 944-MW pressurised water reactor units at North Anna. Unit 1 began commercial operation in 1978 followed by Unit 2 in 1980.
North Anna-1 and -2 have already received initial 20-year licence renewals after the expiry of their 40-year design lifetime and can operate until April 2038 and August 2040.
The NRC said the subsequent 20-year licence renewal means the North Anna units can now operate unit April 2058 and August 2060.
