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 neutronic performance of a hybrid in analysed on the basis of a set of lumped parameters which properly characterize the main features of the hybrid, as energy multiplication or fissile breeding. This analysis enables one to identify the parametric ranges or design windows where a specific hybrid objective can be met. It is shown that fissile fuel production to feed fission reactors requires a set of parameters totally different from that of an energy amplifier hybrid. The latter can be designed to maintain a high factor of energy multiplication for very long burnups. The former reaches the maximum capability to feed fission reactors in the limit of fission-suppressed hybrids, which requires the fertile capture cross section to be as high as possible as compared to the fissile fission cross section. Upper limits of the magnitudes characterizing the neutronic performance are identified.
