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 Product Storage (PS) and Intermediate Storage (IS) systems of the Active Gas Handling System (AGHS) are hydrogen isotope storage facilities. IS will take pure hydrogen mixtures from the Cryogenic Forevacuum (CF) system and store them until the isotope separation systems, Cryogenic Distillation (CD) and Gas Chromatography (GC), are ready to separate the mixtures into pure H2, D2 and T2. The purified D2 and T2 will be sent to PS for storage, while any protium will be diluted with nitrogen and discharged to atmosphere if the T2 levels are below 4 × 10−4Ci/m3. PS will then deliver gas via the Gas Introduction (GI) system to the various users. The principal parts of PS and IS are their U-bed assemblies. Each assembly consists of four uranium beds (U-bed) which each store up to 27 moles of hydrogen. The commissioning results, the absorption and desorption characteristics of the U-beds, the sequences for safe operation of the U-beds and transfer of gases to other AGHS systems, the hardwired interlock system and the over/underpressure protection system for the secondary containments will be discussed.
