Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.”

Typical reactor trip setpoints established for the reactor protection system may be unduly restrictive, depending on how the uncertainties are handled in the plant safety analyses. The current deterministic approaches to establishing specific setpoints contain a substantial amount of conservatism, which can be reduced through the use of a statistical combination of uncertainties process. Using this approach for Three Mile Island Unit 1 indicates that the flux/flow trip set-point can be relaxed to 1.1 from the existing technical specification value of 1.08. This provides an increased plant operating margin and reduction in the probability of spurious scrams.
