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.”

A new nuclear fuel reprocessing plant in Aomori prefecture, Japan, began its reprocessing testing in March of 2006. During testing, tritium-contaminated wastewater was intermittently released into the coastal sea and diluted by the surrounding seawater. We measured tritium concentrations in seawater along the Pacific coast in the Aomori area to understand its temporal and geographical variation.Coastal seawater samples were collected two or three times a year at four sites along the coast from 2006 to 2009. Samples were enriched by electrolysis up to a volume reduction factor of fifteen. Both tritium and deuterium concentrations were measured to calculate the samples' tritium concentrations.Tritium concentrations obtained in this way were usually below 0.5 Bq/L, but they sometimes exceeded 1.0 Bq/L at the four sites on separate dates. From this result we estimate that the tritium-contaminated water is diluted by the coastal water current or by the stagnating water in the release area while it is discharged.
