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 significant fraction of the tritium inventory of a fusion plant will be in the elemental form HT. A simple model is proposed to calculate early doses following an HT release. The dose is not dominated by the primary HT plume but by deposition of HT into the soil, subsequent oxidation to HTO by microorganisms and the following reemission of HTO. The difficulty of calculating HTO concentrations from a large area source is solved by defining a reemission velocity. All data available from the large scale release experiments in France (1986) and Canada (1987) are used to fit this parameter. With typical worst case conditions one gets an early dose of 0.04 Sv/kg-T as HT at 1000 m distance from the source, building wake effects included. This model can also be used to calculate HTO-release doses and predicts 0.6 Sv/kg-T as HTO for the same worst case condition. About 20 % of this dose is caused by reemission of HTO deposited into the soil. The accuracy of the model is estimated to be a factor of 2 – 2.5 up and down.
