North Anna power plant seeks ESP renewal
Dominion Energy Virginia is seeking a 20-year renewal of the early site permit (ESP) the Nuclear Regulatory Commission issued for its North Anna nuclear power plant site in Virginia. North Anna’s current ESP is set to expire on November 27, 2027.
On July 14, Dominion submitted the ESP renewal request for North Anna; the site in question is adjacent to Unit 1 and Unit 2 of the Louisa County, Va., facility. The NRC acknowledged receiving the application on July 28 and will now review the application before docketing it in the Federal Register and commencing with the review process.
