Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.”

The safety design of the Toshiba Boiling Water Reactor (TOSBWR) was created ∼8 yr ago. The design concept is intermediate between conventional boiling water reactors (BWRs) and the advanced BWR (ABWR). It utilizes internal pumps and fine motion control rod drive, but the emergency core cooling system (ECCS) configuration is different from both conventional BWRs and the ABWR. The plant output is 1350 MW(electric). The design is based on two important philosophies: the positive cost reduction philosophy and the constant risk philosophy. The former aims to improve the cost-effectiveness of safety design; the latter seeks a uniform distribution of plant risk. To implement these two philosophies, the TOSBWR safety design utilized system subdividing and probabilistic risk assessment insights. Because of these philosophies, the TOSBWR safety design has combined large cost reductions with safety improvements. The core damage frequency due to multiple failures is reduced about one order of magnitude compared with conventional BWRs, while the capacity of the low-pressure ECCS is reduced to ∼60% of that of the conventional BWR5.
