Dominion intends to renew North Anna operating licenses

Dominion Energy’s Dominion Energy Virginia unit on Monday notified the federal Nuclear Regulatory Commission (NRC) of its intent to relicense the North Anna nuclear power plant in Louisa County, Va., for an additional 20-year term.

The company expects to file a license renewal application for the two-reactor North Anna Power Station in 2020. The company informed the NRC in November 2015 it would file a similar application to renew the licenses of its two Surry (County, Va.) Power Station reactors in the spring of 2019.

"Renewing North Anna Power Station's licenses for a second 20-year period is the right thing to do for our customers, the regional economy and the environment," said Daniel G. Stoddard, chief nuclear officer for Dominion’s nuclear generation division.

The company expects to invest up to $4 billion on upgrades to North Anna and Surry as part of the relicensing process, Kallanish Energy learns.

North Anna’s two nuclear units provide 1,892 net megawatts of electricity, or enough power for 473,000 homes. Unit 1 began commercial service in 1978 and Unit 2 began commercial service in 1980.

Surry’s two nuclear units provide 1,676 net MW of electricity, or enough power for 419,000 homes. Unit 1 began commercial service in 1972 and Unit 2 began commercial service in 1973.

Like all U.S. nuclear units, the North Anna and Surry units were originally licensed to operate for 40 years. All four units' licenses were renewed for 20 additional years of operation on March 20, 2003.

The North Anna and Surry nuclear units' respective licenses currently will expire in 2038 and 2040, and 2032 and 2033. After renewal, the respective licenses for North Anna and Surry will allow the units to operate to 2058 and 2060, and 2052 and 2053.
