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 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. 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 research program to control tritium in supercritical CO2 (SC-CO2) gas-cooled reactors is presented. This type of reactor is attractive because it offers higher thermal efficiency and lower reactivity with the primary coolant. This program consists of two activities; development of tritium permeation barriers in the heat exchanger tubes and development of tritium removal method from the SC-CO2. For permeation reduction, a glassy coating was developed as the tritium permeation barrier for the SC-CO2 system. Experimental results showed the physical and chemical integrity of the coating for 100 hours soaking in the SCCO2. Significant permeation reduction of 1/20 to 1/60 are obtained. But, further permeation reduction is desired through a new coating technique development, since the permeation reduction at lower temperatures is small.
