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.”

The limits on the cavity gas density required for beam propagation and condensation times for material vaporized by target explosions can determine the maximum repetition rate of heavy-ion fusion (HIF) driven reactors. If the ions are ballistically focused onto the target, the cavity gas must have a density below roughly 3 × 1012cm-3 at the time of propagation; other propagation schemes may allow densities as high as 1 Torr or more. In some reactor designs, several kilograms of material may be vaporized from the target chamber walls by target-generated X rays, raising the average density in the cavity to 3 × 1018 cm-3 or more. A one-dimensional combined radiation hydrodynamics and vaporization and condensation computer code has been used to simulate the vaporization and condensation of material in the target chambers of HIF reactors. Repetition rates in excess of 1 Hz are possible in the three types of target chambers studied. Means of increasing allowable repetition rates are discussed.
