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.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

Recently, development on the new concept of advanced small modular reactor, so-called Autonomous Transportable On-demand reactor Module (ATOM) was started in Korea. Major design objectives of the ATOM are adopting Dry Air Cooling System (DACS) and developing passive safety systems. Among several passive safety systems, the Passive Residual Heat Removal System (PRHRS) is crucial since it prevents a core to be damaged by decay heat. Generally, it is known that a currently considered PRHRS has a limitation of cooling capability after all of the stored water is vaporized. In this study, the PRHRS coupled with the DACS (PRHRS+DACS) is suggested to overcome the limitation. The objectives of this study are to assess cooling capability of PRHRS+DACS and to investigate the effects of the design parameters using the MARS code. The simulation results show that the time for PRHRS to maintain its cooling capability is extended by applying the DACS. Furthermore, the effects of the environment temperature and heat transfer area ratio on the cooling capability of the DACS was confirmed.
