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.

Developing a new regulatory framework for advanced reactors: Update on Part 53
White
The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) on March 29 held another presentation in its monthly Community of Practice (CoP) series. The presenter, Patrick White with the Nuclear Innovation Alliance (NIA), talked about the current status of efforts to develop a new regulatory framework for advanced reactors—known as 10 CFR Part 53 or simply Part 53. White serves as the research director of the NIA, where he leads their research as well as analysis-based stakeholder and policymaker engagement and education. White’s March 29 presentation is publicly available on YouTube and at ANS’s publication platform Nuclear Science and Technology Open Research (NSTOR).
RP3C chair N. Prasad Kadambi opened the CoP with brief introductory remarks about the RP3C before he welcomed White as the session’s presenter.
White covered three main topics: the history of the existing regulatory frameworks for new reactors, progress to date on the development of the Part 53 rule for advanced reactors, and the current status and next steps for the Part 53 rulemaking process.

Some variations and extensions of a Fuel Cleanup System based on the combination of palladium diffuser and a vapor electrolysis cell were studied to improve the flexibility to accept broader range of flow rate, gas contents and operation modes. Processing of inert gas - CH4, H2, He2O mixtures in a closed loop showed satisfactory detritiation, with the processing of methane by catalytic steam reforming and oxidation, and electrolytic oxidation. The decomposition of hydrocarbon on the anode side of the ceramic electrolysis cell was tested to study the feasibility as an oxidizer. The zirconia ceramic membrane with Pt electrode are tested with methane at the anode for oxidation, and water vapor on the cathode for reduction. The cell converted methane to carbon dioxide and vapor with high efficiency and simultaneously decomposed water vapor to hydrogen. This application of the cell simplifies the process, and eliminates the use of catalyst and oxygen gas. A versatile fuel cleanup that eliminates most of previos concerns and improves the performance is proposed.
