Documentation Package Supporting Fabrication of Doped UO2 Samples for MiniFuel Irradiation and Fission Gas Release Benchmarking
- Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)
The Oak Ridge National Laboratory (ORNL) is looking into the fabrication of high performance UO2 fuel candidates via the addition of dopants to the UO2. The addition of dopants is proposed to cause enlarged grains that will slow down fission gas release from the irradiated fuel pellet candidates. The Cr-doped UO2 pellets were fabricated from a microspherical feedstock, and enlarged grains were observed during the microstructural characterization. Irradiation under the Miniature Fuel program in the High Flux Isotope Reactor at ORNL will enable the study of irradiation response of such potential fuel candidates and will allow fission gas release benchmarking for these fuel candidates.
