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 salient characteristics of bulk getters are reviewed. The operation of a bulk getter is explained by a theory which incorporates the effects of surface reactions and bulk diffusion. Solutions are summarized for the particular scenarios involving pumping at a constant pressure and desorption at a constant pumping speed. Hydrogen pumping and desorption measurements of ZrAl and ZrVFe bulk getters validate these predictions. From these data it is possible to extract the sticking coefficient, solubility and diffusivity. Using these materials parameters, the performance of the getter can be predicted for any operating regime. Related experiments which examine the isotopic dependence of the hydrogen solubility and a method for achieving the enhanced desorption of a hydrogen isotope are summarized.
