Abstract

It is widely accepted that the current status of neutronics calculations for fast reactor design is such that the present uncertainties on nuclear data should still be significantly reduced, in order to get the full benefit from advances in modeling and simulation. Only a parallel effort in advanced simulation, high-accuracy validation experiments, and nuclear data improvement will provide designers with more general and wellvalidated calculation tools to meet tight design target accuracies to further improve safety and economics. The present paper presents very recent results related to nuclear data uncertainty impact assessment and target accuracy requirements for advanced reactor systems.
