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.”

Due to its low vapor pressure, the Sn-Li eutectic has been identified as a potential breeder for deployment in the liquid first wall (FW)/Blanket concepts under investigation in the APEX study for high power density fusion reactors. However, its breeding capability is limited. This drawback is rather improved due to the neutron multiplication via Sn(n,2n) reactions. However, the "local" tritium breeding ratio (TBR) was found to be still on the marginal side (even with 90%Li-6 enrichment). Aside from using a beryllium multiplier, other means to improve the capability of Sn-Li for breeding are explored. In this paper, we show that by isotopic tailoring of Tin in the Sn-Li breeder, one can achieve substantial improvement in TBR in addition to attaining significant reduction in the activation level in this material.
