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 impact of swelling and creep phenomena, as expressed in the various Nuclear Systems Materials Handbook correlations and their updates, on liquid-metal fast breeder reactor (LMFBR) fuel assembly duct design and LMFBR performance was investigated. As more data on irradiation-induced creep and swelling became available, the predicted creep and swelling rates increased. This leads to increases in interassembly gaps required for the same duct life. Penalties in breeding ratio, doubling times, and fuel cycle cost are the result of the increased interassembly gaps. The most significant penalties are encountered when the updated correlations on creep and swelling are used to update the duct life calculation. To compensate for increases in predicted duct dilation, the duct lifetime has to be reduced significantly.
