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.

A procedure was developed for measuring the concentration of copper, in the Instrumental Neutron Activation Analysis method, by measuring the produced 64Cu isotope activity (after irradiation) from the annihilation peak (511-keV peak). In this procedure the number of counts under the annihilation peak is divided into two categories: (a) counts coming from the decay of the 64Cu isotope and (b) counts coming from the interactions of energetic photons (with energies >1.022 MeV, the pair production threshold) with the detector and surrounding materials. The last category is evaluated and subtracted from the annihilation peak counts, and the rest of the counts are used to calculate the activity of 64Cu. Measuring copper concentration using this method will improve its detection limit. The method was validated by measuring the concentration of copper in four International Atomic Energy Agency (IAEA) reference materials: Soil-7, Lake Sediment, Human Hair, and Hay Powder. The maximum deviation between the results and that given in IAEA certificates is 4.4%. The method decreased the detection limits of the four samples to ~3, ~4.5, ~0.6, and ~1 mg/kg, respectively.
