An inspection of the Millstone Unit 2 nuclear power plant in Connecticut started to review problems related to a leaking relief valve.

Two Nuclear Regulatory Commission (NRC) inspectors arrived Tuesday to review issues related to the “unusual event” declared Oct. 4 at the Waterford, CT, facility. It was the lowest of four levels of emergency classification.

The initial review of the event raised questions regarding operator performance, said NRC Region I Administrator Dan Dorman.

Millstone is investigating and “looking for opportunities to improve performance,” said spokesman Ken Holt.

Millstone, owned by Dominion Resources Inc., was preparing a refueling and maintenance outage when the incident occurred. A reactor coolant system leak linked to a relief valve on the shutdown cooling system used to provide cooling when the reactor is out of service.
