NRC issues corrective actions against Millstone 2 nuclear unit

Millstone 2 nuclear unit has corrective actions from NRC

Dominion (NYSE: D) is implementing a range of corrective actions at the Millstone Unit 2 nuclear plant in Connecticut to address violations.

In September 2011, the NRC became aware that Dominion had submitted requests for approval of amendments to the Millstone 2 operating license that were incomplete and inaccurate. The requests were to modify requirements for Unit 2’s charging pumps and irradiated fuel decay time. NRC’s Office of Investigations began an investigation the following November to determine if there was any wrongdoing. On April 29, 2015, NRC notified Dominion that the violations were considered for escalated enforcement.

The first violation was for a willful violation for changes made to the plant’s Updated Final Safety Analysis Report, without a license amendment, that removed credit for a specific type of safety-related pump in the mitigation of a plant accident. The second violation was a non-willful violation for a failure to provide complete and accurate information to the NRC pertaining to the changes. The third violation, related to the utility’s failure to obtain a license amendment prior to making changes related to spent fuel pool heat-load analysis, was not considered for escalated enforcement.

NRC agreed not to pursue further enforcement action against Dominion in exchange for the company taking corrective actions, including making any necessary changes to plant procedures over the operation and testing of the charging pumps, issue a fleet-wide communication to reinforce the importance of providing complete and accurate information to the NRC; submitting a license amendment request to the NRC addressing the use of charging pumps and other steps. The settlement was achieved under NRC’s Alternate Dispute Resolution process.
