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 multiphase, transient, and three-dimensional interaction of molten corium with water during the premixing phase of a steam explosion is simulated in the QUEOS facility using a large number of small solid spheres at temperatures up to 2300 K. The objective of the experiments is to establish a database for testing the models of heat and momentum transfer in multifluid codes as well as the codes' capability to correctly describe multiphase flows. Three experiments with up to 10 kg of spheres made of molybdenum are discussed. Results from calculations with the IVA-KA code are compared with experimental data. The agreement obtained is encouraging, and the calculations show that the intense multiphase interactions obtained in QUEOS constitute very critical and thus valuable test cases.
