Dominion seeks to fix Millstone issue

Dominion (NYSE:D) is working to fix a relay problem and return the Millstone 2 nuclear unit to service after an unexpected shutdown over the weekend.

Millstone 2 shut down unexpectedly Saturday Nov. 9 due to a problem with a circulating water pump, the company said in a Nov. 11 email to GenerationHub.

After some troubleshooting, Dominion traced the problem to a faulty relay.

The relay will be fixed and the unit will be returned to service, a Dominion spokesperson said in an email. The company did not offer a target date for the work to be completed.

Millstone is a dual-unit station that employs pressurized water reactor (PWR) technology. The combined output of the plant is more than 2,000 MW.
