Media CoverageFukushima Flex Dome Completed at Dominion Nuclear Power Plant - Power Engineering

The first of three storage facilities were completed for Dominion Generation (NYSE: D) at the North Anna nuclear power plant in Virginia.

The 10,387 square-foot steel-reinforced concrete dome is 120-feet in diameter, 38-feet tall and features two hardened equipment doors. The dome was built in response to the U.S. Nuclear Regulatory Commission’s order with specific requirements for mitigation strategies for beyond-design basis external events. The order was in response to the Fukushima Daiichi nuclear incident in Japan in 2011.

The dome was engineered by Engineering System Solutions in alliance with American Business Continuity Domes (ABC Domes) and Dome Technology. ABC Domes is working on two other dome projects for Dominion, one for the Millstone Power Station in Connecticut and one for the Surry Power Station in Virginia, which are scheduled for completion in October and December of this year. The team also has seven other Fukushima Flex domes under development for two other U.S. utilities.
