Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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 straightforward numerical-graphical method is applied to achieve a flat fission power density (FPD) in a catalyzed deuterium-deuterium fusion-driven hybrid blanket by using a mixed fuel made of a nuclear waste actinide (244CmCO2) and natural UO2 with variable fractions of fuel components in the radial direction. The FPD could be kept quasi-constant over a relatively long plant lifetime. The peak-to-average FPD increases from 1.071 at start-up to ∼ 1.074 after 18 months’ operation. The plant availability factor is 60% under a first-wall fusion neutron flux load of 1014 x 2.45- and 1014 x 14.1-MeV neutron/cm2.s, corresponding to ∼2.64 MW/m2. This eliminates the fuel management requirements for at least 18 months of plant operation. The investigated blanket breeds high-quality nuclear fuel (239Pu and 245Cm) and also produces electricity. The overall blanket multiplication factor M increases from 9.4 to only 9.8 in 18 months. This allows an optimal exploitation of the nonnuclear part of the power plant.
