Dominion (NYSE:D) has returned the North Anna 2 nuclear unit in Virginia to service after conducting a regularly-scheduled refueling and maintenance outage.
North Anna Unit 2 returned to service on Saturday morning April 9 at approximately 9 a.m., according to a company spokesperson. The unit was listed at 48% generation early April 11, according to Nuclear Regulatory Commission (NRC) data.
The outage had started around March 6.
Key activities during this outage included a modification to the reactor coolant system to prevent conditions that can damage fuel assemblies. This modification had already been performed on the Unit 1 reactor, the Dominion spokesperson said.
Also, workers implemented an electrical cross-tie modification that will provide alternate electrical supply capability to the emergency busses, enhancing the station’s ability to respond to abnormal conditions.
North Anna Units 1 and 2 are located in Louisa County, Virginia and operated by Dominion’s Virginia Electric and Power Co. Both units are pressurized water reactors (PWRs). Each unit has a nameplate capacity of 980 MW.
