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 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. 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 way to estimate the tritium breeding ratio in a D-T fusion power reactor to assure a self-sustainable tritium system is discussed in this paper comparing the required breeding ratio obtained from tritium balance in the fueling system of a power reactor including the plasma vessel with the attainable breeding ratio evaluated from efficiency in neutron usage and recovery efficiency of bred tritium in the blanket system. It is certified that recovery of tritium from the re-deposition layer together with suppression of the permeation loss through first wall and reduction of the total tritium inventory are effective to ease the tritium balance. It is not preferable to have the burning plasma of which overall burning efficiency is less than 0.5% from the viewpoint of tritium balance of a power reactor.
