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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

The deviations brought by the embedded self-shielding method with the pseudo-resonant isotope model is investigated. Numerical results show that error sources mainly come from the inconsistency in the heterogeneous resonance integral (RI) generated in the two-dimensional square pin–cell case with reflective boundary conditions. The high-order resonance interference effect also contributes to the deviation. The black assumption on the macroscopic cross section of the fuel is proposed to enhance the consistency in the generation of the heterogeneous RI table. Numerical results show that the modification on the original embedded self-shielding method improves the accuracy of the cross-section prediction in the multifuel lattice systems.
