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.

Argonne’s NSTF: Active testing of passive cooling
A facility at Argonne National Laboratory has been simulating nuclear reactor cooling systems under a wide range of conditions since the 1980s. Its latest task, described by Argonne in an August 13 news release, is testing the performance of passive safety systems for new reactor designs.
Designed as a half-scale model of a real reactor system, Argonne’s Natural Convection Shutdown Heat Removal Test Facility (NSTF) is used for large-scale experimental testing of the performance of passive safety systems, which are designed to remove decay heat using natural forces including gravity and heat convection. Those tests yield benchmarking data qualified to the level of National Quality Assurance-1 (NQA-1) that is shared with vendors and regulators to validate computational models and guide licensing of new reactors and components.

A double ionization chamber employing a thin coating of enriched 6LiF radiating material offers an effective means of identifying a 6Li(n, α)t reaction. The concept is based on the detection of ionization caused by alpha particles and tritons. The charged particles emitted in opposite directions can be detected by a double parallel plate ionization chamber configuration. This method can therefore be employed to directly measure tritium breeding rates inside the fusion blankets. Complete details of the parameters that govern the response of such a detector system are described. A Monte Carlo scheme is developed to determine the direction and energy lost by the particles in traversing various media, and the detector response is calculated from the energy deposited in the ionization region of each chamber. The calculations are performed for the entire energy range of neutrons available in the fusion blankets.
