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.”

An autoclave and a water treatment and monitoring system simulating the secondary side of a steam generator are used to investigate the hideout phenomena of sodium chloride in a tube-support-plate crevice. The primary-side heating tube is simulated by an internal heater. The experiments are performed at 1 atm pressure. The effects of heat flux, bulk concentration, crevice width, and the presence of a porous medium are investigated. It is found that the solute concentrates heavily near the upper end of the crevice. This concentration distribution in the axial direction is confirmed by a model developed in a parallel study. The hideout rate increases with increasing heat flux and bulk concentration. The concentration level in the crevice at a given time increases with increasing heat flux and bulk concentration and with decreasing crevice width. The presence of a porous medium in the crevice significantly enhances the concentration effect.
