Validation of three cross-section libraries used with the SCALE system for criticality safety analysis

The calculations and analysis of two series of recently performed critical experiments are presented. Three cross-section libraries available in the SCALE system are used in the analyses. The results obtained are discussed in detail and are compared with MORET code calculations. The comparison with experimental results validates the cross-section libraries and allows an optimistic approach to the results of future studies using the three libraries and the SCALE system.
