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.”

Light water reactors (LWRs) are expected to be a primary source of electrical power in Japan into the 21st century. A next-generation LWR must be developed that efficiently uses uranium resources and improves fuel economy. A high-conversion boiling water reactor (BWR) core design is proposed that conserves natural uranium through a high conversion ratio that is achieved through efficient utilization of the vapor void in the BWR core. The proposed reactor concept employs fuel bundles with a square channel box and cruciform control rods, which are commonly used in conventional BWRs. Thus, it is possible to use current BWR core internals and vessel designs with minimal modifications, which makes the entire reactor system design more feasible.
