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.”

A system has been developed for the production of 99mTc based on distributed electron accelerators and thermal separation. The radioactive decay parent of 99mTc, 99Mo, is produced from 100Mo by a photoneutron reaction. Two alternative thermal separation processes have been developed to extract 99mTc. Experiments have been performed to verify the technical feasibility of the production and assess the efficiency of the extraction processes. A system based on this technology enables the economical supply of 99mTc for a large nuclear pharmacy. Twenty such production centers distributed near major metropolitan areas could produce the entire U.S. supply of 99mTc at a cost less than the current subsidized price.
