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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

We present results from radiation-hydrodynamics calculations which show the central role resonant self-absorption plays in reducing radiative energy loss rates in high-gain ICF target chamber plasmas. Calculations were performed using a non-LTE radiative transfer model which we have recently coupled to our target chamber radiation-hydrodynamics code. The lower radiation fluxes escaping the plasma, which occur due to the self-absorption of line radiation in their optically thick cores, lead to significantly lower temperature increases at the surface of the target chamber first wall. The calculations were performed for the SIRIUS-P laser-driven direct-drive ICF power reactor. In this conceptual design study, high-gain targets release approximately 400 MJ of energy in the center of a gas-filled target chamber. The target debris ions and x-rays are stopped in the gas, and the energy is reradiated to the chamber wall over a much longer time scale. Because the time scales are comparable to the time it takes to thermally conduct energy away from the first surface, the thermal stresses and erosion rates for the first wall are greatly reduced.
