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.”

An engineering evaluation of organic coolants for tokamak fusion power reactors was carried out. The primary focus was to assess the degree of radiolytic damage to the coolant and its effect on blanket design and overall operation. Organic coolants are attractive for fusion applications from a safety perspective. They are chemically inert with lithium metal, yield high tritium breeding performance, and possess low volatility and neutron activation. However, radiolytic damage to the organic molecules was found to severely limit their potential. Protected blanket designs were found to be necessary to reduce the damage to tolerable levels (i.e., of the same order as in the fission reactor system). These blankets require a two-fluid cooling cycle that defeats many of the anticipated advantages of using organic coolants. Their future consideration for tokamak systems is contingent on a number of unresolved issues: How compelling safety requirements turn out to be, what levels of activation of the structure are desired, and what advantages result in recovering tritium from organic systems.
