Abstract

The present paper describes experience of IRSN in computational analysis of experiments performed at the BFS facility. The objective of the studies is to contribute to a suit of benchmark experiments useful to validation of neutronics simulation for fast reactor safety analysis. The BFS configurations provide valuable information to the validations, being rather complex configurations for design-oriented codes. The use of Monte Carlo software codes minimises code dependent errors and provides reference solutions for validation of the designoriented codes. Monte Carlo MORET 5 code, developed at IRSN, and SCALE codes system, developed at ORNL, were applied for computations of the BFS configurations along with deterministic ERANOS code, used at CEA for fast reactors' simulations.
