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.”

The control of plasma rotation in a tokamak by controlling the impurity content is investigated. A neoclassical theory for momentum transport by collisional ions in a tokamak plasma with strong neutral beam injection and strong rotation is developed. A consistently ordered hierarchy of approximations to the kinetic equation are derived and solved to obtain expressions for particle flows, the radial electric field, poloidal asymmetries in density and potential, and the radial flux of toroidal angular momentum and the associated torque that acts to damp toroidal rotation. Upon decomposing the first-order distribution function into gyroangle-dependent and gyroangle-averaged components, neoclassical gyroviscosity is recovered from the former, and a new “rotational” viscosity of a collisional origin is recovered from the latter. The same viscosity coefficient and functional form are obtained for both types of viscosity.
