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 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. 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.”

Focusing on synthetic zeolites that adsorb hydrogen isotopes at liquid N2 temperature with priority in the order of T2, DT, D2, HT, HD and H2, we have been developing a pressure swing adsorption process system for hydrogen isotope separation. For this purpose, we carried out fundamental experiments of adsorption and desorption of a tracer D2 in bulk H2 with zeolite packedbed columns. In this paper, the results are reported that D2 is enriched in the adsorbed phase at separation factors near 2.0, flowing through zeolite 5A and 13X packed-beds at 77.4 K. These are in agreement with values predicted from the multi-component equilibrium characteristics. In the gas samples recovered by evacuating the packed-beds, however, D2 was detected at a relative concentration of 1.20 or 1.32 to that in the feed gas. This lower range results from the isotopic mass effect in kinetic process. That suggests a highly D2-enriched residual left during evacuation. This is verified with an unusually high enrichment factor of 6.68 or 9.21 for zeolite 5A or 13X measured in the residual sample desorbed from the packed-bed by heating up to room temperature.
