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.

Construction begins on Kairos’s fluoride salt–cooled test reactor
Earlier today, on a site in Oak Ridge, Tenn., that was formerly home to the K-33 Gaseous Diffusion Plant, Kairos Power marked the start of construction on its low-power demonstration reactor. Named Hermes, the 35-MWt test reactor claims status as the first Gen IV reactor to be approved for construction by the Nuclear Regulatory Commission and the first non–light water reactor to be permitted in the United States in more than 50 years.

Annual tritium exposures can be reconstructed for long time periods by analyzing radioactive concentrations in tree rings near nuclear facilities that can release tritiated water (HTO) to the environment. Since the mass of analyzed samples is on the order of milligrams, usual methods such as liquid scintillation counting cannot be applied. The recommended method comprises thermal decomposition of the milligram-sized samples, reduction of the resulting HTO to tritiated hydrogen, quantitative absorption of titanium hydride (TiHT) in titanium powder, and determination of the H/T ratio using an accelerator mass spectrometer method. This paper describes the method for obtaining TiHT standards with different H/T isotopic ratios for calibration of a mass spectrometer detector.
