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.”

Pyrochemical processing (pyroprocessing) was developed to recover plutonium that is inherently comingled with minor actinides, uranium, and fission products and has been studied with the aim of recovering actinide elements from spent nuclear fuel. Although a significant amount of attention has been given to pyroprocessing technology as a future fuel recycling system, safeguards approaches are challengeable because of a lack of international experience with safeguarding pyroprocessing facilities beyond those at a pilot scale. Safeguards have primarily depended on nuclear material accountancy with the measurement uncertainties inherent in nuclear material flow. When the weakness of nuclear material accountancy is addressed, the quantity of material unaccounted for (MUF) is generally regarded as an important measure of the safeguardability of a facility. Statistically, the observed MUF is a random variable that is an estimate of the true MUF because the observed MUF is affected by measurement errors. The MUF uncertainty can be calculated by properly combining the random error and systematic error of the nuclear material accounting measurement. Therefore, in this study, a conceptual design for estimation of the uncertainty of MUF that can occur in a reference pyroprocessing facility (REPF) is developed, where REPF is a model used to optimize the safeguardability of a future pyroprocessing facility.
