North Anna Reactor Back in Service after Shutdown

Posted: Updated:

LOUISA, Va. (AP) - A nuclear reactor at Dominion Virginia Power's North Anna power station is back in service following an unplanned shutdown.

The utility was restarting Unit 1 following a scheduled refueling and maintenance outage when the reactor automatically shut down last Thursday.

Dominion Virginia Power tells the Richmond Times-Dispatch that a protection relay associated with a station service transformer caused the shutdown. The utility says workers hadn't returned the relay to its proper operational configuration.

Unit 1 was returned to service on Sunday afternoon.
