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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Uranium oxide (U3O8) nanoparticles were synthesized and coated in situ with porous, mesostructured silica using a modified sol-gel method for use as a catalyst. The catalytic property of coated U3O8 nanoparticles was evaluated by exposing them to an aqueous solution of benzene at 500 mg/l at room temperature. The presence of benzene was not detected by an ultraviolet (UV)-visible (UV-vis) spectrometer after 6 weeks of exposure to coated uranium oxide nanoparticles, indicating the particles' potential as a catalyst. Based on the results of the benzene destruction, it may be suggested that the coated U3O8 nanoparticle-based catalyst has the potential to destroy hydrocarbons, aromatics, and various toxic substances such as perchlorates and 1,4-dioxane from groundwater. However, further experiments are necessary to explore the full potential of the catalyst. Pluronic-123, n-butanol, and 2-propanol were used as surfactant, cosurfactant, and continuous phase, respectively, for the synthesis of the U3O8 nanoparticles, which were formed through nucleation, growth, and subsequent aggregation in the solution phase. The nanoparticles were coated in situ using an aqueous solution of tetraethyl orthosilicate. The coated particles were characterized using transmission electron microscopy, diffuse reflectance infrared Fourier transform spectroscopy, nitrogen physisorption, X-ray diffraction, and diffuse reflectance UV-vis spectroscopy. These measurements revealed that U3O8 particles ranging from 4- to 10-nm were distributed exclusively inside the silica matrix.
