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.”

Powerful neutral beams used in many present-day magnetic fusion devices to heat the plasma to high temperatures must pass a region of finite background pressure where the magnetic stray field is rather high. Reionization of neutral beam particles and their subsequent deflection onto walls may lead to serious power loadings if no proper protection is provided. The simulation of this problem for the neutral beam injection system of the ASDEX-Upgrade tokamak is examined. The magnetic field distribution and the particle trajectories are calculated in full three-dimensional geometry. The statistical methods applied to simulate the ∼106 beam particles necessary to obtain a reliable power density distribution on the various surfaces of the duct region are described in some detail. Results are given for different magnetic field configurations of the tokamak. Because of the focusing effect of the strongly varying magnetic field, power densities in excess of 2 MW/m2 are found in extreme cases. Additional large area shieldings are installed to protect the most exposed regions of the entrance port of the vessel.
