The present paper focuses on the modeling of the CROCUS reactor with the French MORET 5 continuous energy code and compares keff, anti-reactivity effects (variation of keff normalized to keff due to the insertion of an absorber), sensitivity coefficients and kinetics parameters with those provided by other reference codes. The aim is mainly to extend the experimental validation database of the MORET 5 code to use reactor physics applications. A suite of about 1400 benchmarks is already available for criticality but only a few are dedicated to reactor physics applications. The CROCUS reactor configurations therefore constitute an opportunity to test and improve the implementation of kinetics parameters and sensitivity coefficients in the code and ascertain reactivity effects.
