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.”

This paper summarizes the results of an independent review of information from the available literature on plutonium release parameters obtained in worldwide studies on accidental fires that might occur in nuclear facilities and generates technically justifiable recommendations on plutonium releases based on this review. This work was limited to the accidental fires in nuclear facilities involving plutonium-contaminated waste materials that can be in either solid or liquid form, as well as involving plutonium metal itself. Releases of plutonium are expressed in terms of the airborne release fraction (ARF), defined as the total fraction of initial material released in the accident, or the airborne release rate, which is the average rate at which ARF is released for the duration of the accident. Respirable fraction of the mass of plutonium dispersed in the air is conditionally assumed to include particles having aerodynamic diameters smaller than 10 m (aerodynamic diameter of a particle is defined as the diameter of a unit density sphere having the same aerodynamic properties as the particle; particles of any shape or density will have the same aerodynamic diameter if their settling velocity is the same). For intense fires in solid waste storage areas or large explosions associated with plutonium metal, up to 50% of the plutonium contamination may be released as respirable aerosol.
