Dominion Energy will undergo oversight and safety evaluations after an investigation found a former security armorer at Millstone Power Station in Waterford, CT, deliberately failed to perform required weapons checks and inventories.
According to an order issued by the Nuclear Regulatory Commission (NRC), the former armorer falsified records between January 2015 and June 2016 to make it appear that on-site weapons were fire-tested, cleaned and accounted for.
The NRC said the individual was a security officer from British security company G4S employed as an armorer responsible for weapons checks. But the NRC investigation, launched Aug. 31, 2016, identified discrepancies on several weapons maintenance records, leading to two security violations.
As part of the order, which followed a mediation session in September, Dominion agreed to a series of corrective actions, including a full inventory of all on-site weapons whether in or out of service. The company also must evaluate G4S training of security officers and the duties of the armorer position.
Dominion then will share the results of the corrective actions with nuclear industry groups, per the NRC order.
“We’ve agreed to a set of actions to ensure this doesn’t recur,” Dominion spokesman Kenneth Holt said in a published report. “We will complete all of them before they’re required to be done and provide the NRC with all the information they need.”
He said each of the dozen corrective actions laid out in the NRC’s order has a completion timeframe ranging from 10 to 250 days.
The NRC said Dominion violated two security regulations: Its obligation to maintain complete and accurate information required by the commission’s regulations, orders or license conditions; and the mandate to keep records of all tests, inspections and maintenance of security-related equipment for three years after such events are documented.
