NSUF 18-CINR-14704: Facilitating MARMOT Modeling of Radiation Phenomena in U-Pu-Zr fuels through experiments (MORPH experiment)
The objectives of this proposal are to increase fundamental understanding of irradiationinducedmetallic U-Pu-Zr fuel behavior and to obtain data needed for the development of irradiation models for metallic fuels in MARMOT. The project requests access to postirradiation examination (PIE) facilities at Nuclear Science User Facility (NSUF) partner facility to conduct examination of irradiated metallic fuels with the goal of providing foundational understanding of the radiation behavior in metallic fuels needed to inform the development of MARMOT models. The requested metallic fuel is from X-441 experiment irradiated in EBR-II and will be provided by PIs for the duration of the experiment. The purpose of the pins irradiated in the X-441 assembly was to vary Zr composition and fuel slug diameter in order to provide data for the metallic fuel performance code “LIFEMETAL” [ANL-IFR-125]. The fuels of interest to this project are metallic fuels with several Zr compositions (in wt.%): U-19Pu-6Zr, U-19Pu-10Zr, andU-19Pu-14Zr, which were irradiated to a peak burnup of ~11 at.%. The cladding was the same for all three fuel pins (austenitic stainless steel D9), which allows investigation of fuel-cladding interaction phenomena. Varying Zr content in fuel pins enables investigation of the effect of Zr on fuel restructuring and fuel cladding compatibility. Large and small scale PIE activities will be focused on investigation of fundamental aspect of fuel performance such as species diffusion and migration, fission product behavior, and constituent redistribution. Obtained microstructural information will be used as the basis for the development of MARMOT models of U-Pu-Zr fuel performance at the mesoscale.
