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.”

NUMO has developed a safety case to confirm previous generic demonstration of feasibility of geological disposal of high-level radioactive waste (HLW) and low and intermediate level waste generated from reproccessing and MOX fabrication (named TRU waste) in Japan and extend this to consider the geological settings that may result from the volunteering approach to siting. The reference groundwater at repository depth and associated radionuclide migration parameters in the engineered barriers, i.e. solubilities, distribution coefficients (Kds) and effective diffusion coefficients (Des), were derived to allow safety analysis for a range of scenarios. In the performance assessment, parameters assessed as the most realistic were used to assess a “likely” scenario. Variations of parameters to account for uncertainties were included in “less-likely” scenarios.
