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.”

Recent developments in z-pinch stability theory and encouraging results from frozen-fiber pinch experiments have led to renewed interest in the simple linear pinch as a possible fusion system. In this paper, a zero-dimensional pinch model coupled to a realistic circuit model is used to establish a point design. It is assumed that the pinch remains stable only as long as the current is rising, and that the magnetic energy can be recovered efficiently after the pinch has gone unstable. It is then shown that a self-sustaining cycle is possible in which circuit losses are balanced by direct conversion of some of the alpha-particle energy, and no net energy input is required. The repetition rate is limited by the rate at which the helium reaction product can be pumped away. A reactor operating at 40 Hz could produce about 350 MWth from a reactor vessel 2 - 3 m in diameter.
