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.

Report touts lessons from era of nuclear waste negotiator
As the Department of Energy embarks on its consent-based process for siting a geologic repository for spent nuclear fuel and high-level radioactive waste, a new report from the Center on Global Energy Policy at Columbia University SIPA highlights relevant lessons from the federal government’s now defunct Office of the Nuclear Waste Negotiator.
Established under Title IV of the Nuclear Waste Policy Act, the office, an independent agency within the executive branch, was primarily active from 1990 to 1995. Its role was to engage with state and tribal governments to find an acceptable and suitable host site for a repository.
The full report, Lessons from the Nuclear Waste Negotiator Era of the 1990s for Today’s Consent-Based Siting Efforts, is now available online. Its executive summary is available here.

The LIMIT computer code is utilized to study the behavior of containment atmospheres following severe core damage accidents. The degree of heterogeneity in passive entity mixing, especially mass stratification, is assessed. Two scenarios are analyzed using a two-dimensional Cartesian 84-node mesh computational domain as the baseline geometry. Both calculations include steam and liquid fields and involve hydrogen injection. Some stratification is observed after source injections are terminated. The formation of the stable mass gradients is caused principally by heat removal to structures located in the lower regions. Preliminary results conclude that in the absence of sprays or fan coolers, stratification can occur depending on the location and heat capacity of energy absorbing/liberating structures.
