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.”

Reactions between the vanadium-base alloy V-1 Si-3 Ti and lithium were studied at 550°C in a forced convection loop made of stabilized austenitic stainless steel. Preheating the lithium in contact with a titanium sponge reduced the nitrogen and carbon levels below 100 wppm. In spite of the low concentrations of nonmetallic elements, the vanadium alloy picked up these contaminants, producing a hardened surface layer. Nitrogen concentrations in the range of 10 to 70 wppm significantly influenced the dissolution rate of the solid alloy. Carbon uptake did not reach these levels. Surfaces of the alloy remained unprotected at the lowest nitrogen levels in the lithium. At higher contents, a protecting compound was detected at the surface of the alloy, reducing the dissolution rate during the corrosion test. Dissolution of vanadium and the minor alloying elements became evident when nitrogen concentration was increased further. Material losses from V-1 Si-3 Ti was only one-tenth of that seen from either austenitic or ferritic stainless steels at the same temperature and flow velocity.
