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.”

Thermal fluid physics associated with natural convection is investigated by using Rayleigh-Bénard convection experiments and numerical simulations. An analogy is proposed between the phenomenon of natural convection and an integrator circuit. This analogy is a logical extension of the resistor circuit analogy for conduction. Both experimental data and thermo-fluid simulations support the proposed model. It is observed that the characteristic time constant of the phenomenon of convection is a function of Prandtl number and acceleration due to gravity. The effect of reduced gravity and increased fluid viscosity is discussed. These results can significantly assist in thermal fluid analysis of future space reactors.
