Virginia utility considers SMRs
Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.
While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”

A new passive safety system to remove reactor decay heat (energy) from water-cooled reactors has been developed. It consists of (a) a natural-circulation heat transfer subsystem to remove heat from the reactor coolant and dump it into the atmosphere and (b) a subsystem that triggers the heat transfer subsystem based on low water levels. The initiating mechanism relies on the difference in the physical properties of steam and liquid water. A preliminary description and performance analysis of the water level-initiated decay energy cooling system are provided.
