Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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 important mechanisms of energy flow in a quasi-isobaric magnetic fusion device are studied. In Part I of this paper, the spatial profiles of plasma parameters that yield acceptable values of Qdt and plasma dimensions are determined. These prof lies are determined by balancing the dominant terms in the differential energy equations, i.e., conduction, brems-Strahlung, and collisional energy exchange, against each other. One class of equilibria was identified for a more detailed study. In Part II, the contributions of inelastic processes, radiation transport, and alpha-particle slowing down to the differential energy balances for electrons and ions are examined. Bremsstrahlung loss is found to be the dominant term for electrons. Inelastic processes involving hydrogen are important for ions in the fusion “core.” Impurity radiation can be important even with a low impurity content. Energy deposition by alpha particles is significant in the high-density edge, while cyclotron radiation transport plays some role in regions with large density gradients.
