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.”

In order to perform deuterium plasma experiments by using the Large Helical Device (LHD), the NIFS is planning to install a system for tritium recovery from exhaust gas. NIFS is planning to apply the latest technologies for tritium recovery. Oxidized tritium (tritiated water vapor) contained in the purge gas is usually removed using an absorbent column. However, if a dew point of less than -60 °C could be obtained using a polymer membrane dehumidifier, the equipment could be reduced in size and a more stable dehumidifying performance could be expected. The applicability of a commercially available membrane dehumidifier has been evaluated experimentally. Based on the performance test results, an actual dehumidifier system that combines a membrane dehumidifier and an absorbent column is proposed and verified to be applicable to the LHD.
