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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Glass thin films appear particularly interesting as semipermeable barriers for many noncryogenic target applications. This functional layer can be sputtered from quartz targets onto CHx microshells synthesized by glow discharge polymerization. In the present work, we investigate the influence of deposit parameters (pressure, RF power, target-holder distance, and plasma composition) on glass coating microstructure and permeation properties. The permeation properties of CHx/SiO2/CHx capsules are studied by mass spectrometry using deuterium (D2) as the filling gas. The use of a low deposition pressure and a high RF power in a background atmosphere of argon appears essential to obtain the most efficient barrier. The optimized sputtering conditions allow deuterium half-lives of 1 month on 1700-m CHx capsules, including a 1-m-thick SiO2 coating (corresponding to a permeation coefficient of 3 × 10-20 molm-1s-1Pa-1). These capsules could be filled to the required pressures ([approximately]3 MPa) for Laser Mégajoule (LMJ) experiments.
