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 new practical method has been developed for calculating neutron-activation inventories of target material in inertial fusion energy (IFE) reactors such as HYLIFE-II. It accounts for irradiation both in the target and in the internal blanket and for material circulation in and out of the primary loop. The continuous removal of target material in the real system is approximated by a batch extraction (BE). A single target is followed through its lifetime in the reactor using “transition matrices” for activation and decay which are generated by the ACAB code package. The inventory of all the isotopes of interest accumulating in the reactor is obtained by superimposing the contribution of single targets. The new BE model simulates, within minutes, the evolution of more than 150 isotopes over the 30-year reactor lifetime, explicitly accounting for the millions of neutron pulses experienced by a single target and summing the inventories of all the targets.
