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.”

A model that accounts for the essential mechanisms of pellet acceleration by two-stage guns is described. Gas compression inside the second stage is assumed to be zero-dimensional, while pellet acceleration is considered one-dimensional unsteady and is solved by the method of characteristics. The coupling between the two parts is explicit. An ideal gas equation of state is used for the entire system. Numerical results are compared with available analytical solutions. A sensitivity analysis showing the influence of many parameters is performed. Comparisons with experimental results are satisfactory, as better than qualitative agreement was obtained. The model was found to be sufficiently reliable and suitable for preliminary studies on different operating conditions and geometries in order to save time and experimental resources.
