A Study of Fuel Cladding Design Parameters for Ultra-Long Cycle Fast Reactors

摘要

In this study, key design parameters for the design ofrnUCFR fuel cladding have been reviewed. Currentlyrnavailable models for internal pressure from fission gasrnrelease, irradiation creep and swelling are discussed. Also,rnthe life prediction model based on Larson-millerrnparameter is applied to get the estimation for creeprnrupture time of candidate materials for fast reactorrncladding materials.
