Dominion’s Millstone-3 nuclear unit in Waterford, Connecticut, returned to service Wednesday after a three-day outage to repair a hydrogen leak, a company spokesman said.
The 1,276 MW unit synchronized with the electric grid at 5:20 a.m. Wednesday, Dominion spokesman Kenneth Holt said in an email.
Millstone 3 was operating at 20 percent of capacity early Wednesday, the Nuclear Regulatory Commission (NRC) said in its daily reactor status report.
For commercial reasons, Holt did not say when the unit should reach full capacity.
Millstone 3 shut down 6:45 a.m. Sunday “due to a main generator hydrogen gas leak into the turbine building,” the company said in an event report to NRC that day.
The source of the leak ended up identified and repaired, Holt said.
Dominion declared an unusual event — the lowest of four classifications of power reactor emergencies that NRC uses — that later terminated Sunday morning.
