Uncertainty Assessment of Gas-Cooled Fast Reactors

摘要

Currently, exploratory design studies of Gas-CooledFast Reactor (GCFR) are based on innovative fuel formswhich could imply the loading in the core of materialsnot yet widely used (e.g. Zr and Si in GFR with carbideparticle fuels). Moreover, the loading of Minor Actinides(MA) in significant amounts (up to 5% of the fuel mass)is also envisaged in waste minimization strategies. It istherefore interesting to evaluate nuclear datauncertainties impact on reactor performance parameters.
