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.

Visco-plastic flow properties of hydrogenic solids are important considerations for the design and operation of continuous hydrogenic pellet extrusion systems. Prior to 2010, the visco-plastic flow behavior of deuterium, tritium, and mixtures of the isotopes was only known at 14 K and no heat transfer studies were available. To address these needs, a Cryogenic Couette Viscometer (CCV) was developed at the University of Wisconsin-Madison. Visco-plastic flow characteristics of solid neon, deuterium, and hydrogen were measured using the CCV from the onset of solidification to sub-cooled solid states over a range of shear rates. This paper discusses the transformation of these measurements, using the Quantum Law of Corresponding States, to predict the visco-plastic flow behavior of solid tritium and deuterium-tritium mixtures. Comparisons of predicted values with experimental measurements are made, where available.
