EVOLCODE validation for boiling water and MAGNOX nuclear reactors

The computational analysis of nuclear reactors, from the points of view of neutronics and depletion, is needed to ensure the safe operation of nuclear reactors and the characterization and management of spent nuclear fuel. For this reason, EVOLCODE (CIEMAT's burn-up code) has been validated in this work for boiling water and MAGNOX reactors, to widen its application range; this code was only validated for PWRs in the past and verified for fast reactors. Information of reactors and irradiation history for the BWR Cooper reactor and for MAGNOX Hunterston A has been taken from the SFCOMPO database. Hence, this work contributes to widening the Spanish capabilities in terms of the neutronics analysis of nuclear reactors and the characterization and management of spent nuclear fuel.
