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 integrated analysis of Mark-I liner attack in a postulated core-melt accident is presented. The approach consists of the mechanistic treatment of the sequence of physical phenomena that lead to liner contact by corium debris and their coupling through a probabilistic framework that allows representation of uncertainties. A physically consistent treatment in each sequence is emphasized, but qualitatively different scenarios to represent the range of behavior due to model uncertainties are allowed. The results are presented in a format that allows their direct use in probabilistic risk assessments; in particular, expert opinion is incorporated by a new methodological approach that involves expert review of, and comment on, a fully documented study all under one cover. The study itself is presented in three parts here; the expert inputs can be found in NUREG/CR-5423.
