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.

The results of in-pile tests on UO2 specimens of fine-grain and single-crystal structure led to the formation of a defect-trap theory to describe fission-gas release. The theory, which applies only when the UO2 temperature is below the grain growth region (≈1600° C), is described, and confirming experiments are cited. Experimental results are given to support the contention that a knock-out mechanism accounts for the majority of the fission-gas release at UO2 temperatures under 600° C. An oscillating experimental technique developed to evaluate the defect-trap theory is described, and the initial results are interpreted in terms of the theory.
