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.

Extended cycle lengths and fuel burnups are receiving increased attention. Frequently, the attendant fuel management strategies in pressurized water reactors (PWRs) require burnable poison shims to control power distribution and to maintain a negative moderator coefficient. High energy (∼450 effective full-power days) fuel cycles utilizing both out-in and low-leakage assembly placement schemes provide some insight to the relative merits of UO2-Gd2O3 (gadolinia)- versus boron-bearing shims for PWR applications. Relative to using boron-bearing burnable shims in PWRs, gadolinia has important potential advantages and disadvantages. With proper application, the advantages point to a reduction in fuel cycle costs and increased fuel management flexibility. However, for proper application, the more complex gadolinia neutronics and thermal-mechanical design characteristics must be modeled accurately.
