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.”

In pyrometallugical reprocessing, the spent electrorefiner salt containing fission product (FP) elements may be purified by zeolite and reused. Batch-type absorption tests were conducted using one or two FP chlorides in a LiCl-KCl eutectic electrolyte in order to obtain absorption isotherms to fit to a Langmuir equation model. For the trivalent FP elements in the one-component or two-component systems, the FP-element uptake in the zeolite can be related to its concentration in the salt using a single Langmuir-type equation. In contrast, for monovalent and divalent FP elements, it was necessary to use three different Langmuir-type equations. Using these derived absorption equations and a stage concentration diagram, it was found that only a three-stage process is required to attain a decontamination factor of 50 for trivalent FP elements via a countercurrent multistage process.
