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.”

This study is devoted to the collection and robust analysis of 2008-2009 field data pertaining to airborne tritium transfer in potato and tomato plants subject to continuous releases. The study is a part of implementation and validation of tritium transfer model ported to Canadian LAnd Surface Scheme (CLASS), which has been recently extended towards plant phenomenology in Canadian Terrestrial Ecosystem Model (CTEM+CLASS v.2.7). The initial validation has been performed for ratios of organic to free-water tritium in plant tissues (OBT/HTO ratios) retrieved from the simple off-line tritium uptake and re-emission routine assessed against historical OBT/HTO ratio datasets. The observed underestimate of high OBT/HTO ratios in this simple model warrants deployment of CTEM+CLASS and makes it necessary to focus the next experimental validation effort at tritium re-emission phase. The concentration of HTO in the upper soil layer, in the different parts of vegetation and in the air has been assessed. The sampling was performed on weekly and hourly scales, in the latter case with emphasis on a night-time period. The process of uptake from atmosphere has been clarified using plants grown on the clean tarp-covered soil at Acid Rain Site of Chalk River Laboratories (CRL), which dumped the root uptake pathway. The processes of root uptake and re-emission from plant were clarified at the irrigated Perch Lake site of CRL. Auxiliary environmental drivers and site-specific data were collected according to format of inputs and parameterization of CTEM+CLASS.
