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.”

Assuming a practical use in ITER facility, rapid recovery and supply of tritium to accommodate pulsed plasma operation cycle with minimal inventory was tested. For this purpose, tritium will be supplied from heated bed with vacuum pump while heat of reaction is supplied externally. For recovery, hydriding reaction occurs at elevated temperature spontaneously. Kinetic behavior of the bed at the temperature around 300 degree-C was studied, and practical operation was successfully demonstrated. Isotopic composition change due to the difference of equilibrium temperature was concerned in supplying mixture, but the effect was found to be negligible. For rapid accountancy, ITER requirement of accuracy (± 1%) was demonstrated by 25 g tritium storage ZrCo bed with “In-bed” gas flowing calorimetry. It was revealed that the accuracy is affected by the surrounding temperature, that could readily be controlled for better measurement. Thus technology and experience on storage and transport of large amount of tritium, that are inevitable in fusion tritium facility such as ITER Tritium Plant have been established by Japanese research facility and industry.
