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 potential development and deployment of a standardized canister system represents an opportunity for an integrated approach to address the storage, transportation, and disposal issues in an integrated waste management system (IWMS). However, this deployment has the potential for significant system-wide impacts regardless of timing and method of implementation. This paper describes an evaluation that investigates using standardized, triple-purpose (storage, transportation, and disposal) canisters within the IWMS. Specifically, this evaluation documents a quantitative comparison of the impacts of implementing standardized canisters against the status quo of continuing to load existing canisters that could be challenging to dispose of in a number of different geologic repository concepts being considered by the US Department of Energy. This evaluation focuses on spent nuclear fuel that (1) would be loaded into standardized canister systems at reactors or (2) would be transported to an interim storage facility in reusable, bolted-lid transportation casks and subsequently loaded into standardized canister systems. Specifically, the evaluation builds on previous work to gain a better understanding of (1) the impacts of leaving spent fuel pools open for extended periods of time to facilitate access to the fuel and (2) how updated concepts of packaging for disposal and associated costs impact the system-wide evaluation.
For all standardized canister scenarios analyzed, the following observations can be drawn from this evaluation:
(1) Beginning to load standardized canisters either before or when a repository concept is selected would reduce the total life cycle cost of the system by between 1% and 7% when compared with the current “business as usual” approach of continuing to load large, dual-purpose canisters (DPCs), assuming that disposal of DPCs is determined to be unfeasible.
