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.

Direct waste transfer process quickens at Savannah River Site
The Department of Energy Office of Environmental Management’s liquid waste contractor at the Savannah River Site this month marked the first direct transfer of decontaminated waste from the Salt Waste Processing Facility (SWPF) to the Saltstone Production Facility (SPF). This is a new step in optimizing waste processing, according to the DOE.

Experiments on the thorium-loaded accelerator-driven system (ADS) were carried out at the Kyoto University Critical Assembly to reevaluate the accuracy of reactor physics parameters, including prompt neutron decay constants reaction rate distributions, subcriticality, and subcritical multiplication factor, and to reveal the dependency of these parameters on the external neutron source by varying the external neutron source of 14-MeV neutrons and spallation neutrons generated by 100-MeV protons. In preparation for thorium-loaded ADS experiments, renewed irradiation experiments are conducted with small and thin foils of thorium in the critical state to reevaluate the accuracy of the experimental analyses. In the ADS experiments, reactor physics parameters are found to be different in the same core when the external neutron source is injected separately with 14-MeV neutrons and spallation neutrons. By comparing with the calculated results, the significant impact of external neutron sources on the neutron characteristics of ADS is obtained in both the static and the kinetic experimental analyses.
