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.

Hydrogen trapping in molybdenum was studied by use of an in-situ observation technique of deuterium depth profiling. A sample sheet was exposed to a deuterium plasma and deuterium permeation through it was monitored. The plasma-facing side was bombarded with 3He ions and deuterium depth profiles were observed by a nuclear reaction analysis under the plasma exposure. The result showed that traps, probably vacancies associated with radiation damages, were produced by the ion bombardment. From consideration of an equilibrium between trapped and dissolved deuterium, the equilibrium constant was estimated from the experimental data and the trapping energy of 1.1 eV was obtained. The production rate of the traps was found to be 0.007 from evolution of the concentration of trapped deuterium with the number of atomic displacements.
