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.

As an explosion of radiolitically generated hydrogen is listed as a type of severe accident in the new regulation for nuclear fuel cycle facilities, it is important to evaluate the realistic source term of this type of accident. The airborne release fraction (ARF) is a key parameter in evaluating the source term of a hydrogen explosion. Therefore, a pressurization experiment and a hydrogen explosion experiment that induced a hydrogen explosion have been performed. As a result, the ARFs obtained from the pressurization experiment and hydrogen explosion experiment were approximately 1 × 10−5 and 1 × 10−6, respectively. There was no marked difference in the pressure dependency and liquid droplet particle size between the pressurization and hydrogen explosion experiments.
