Résumé

This workshop investigates the usage of computer codes from a Nuclear Criticality Safety standpoint rather than from a criticality code standpoint. Indeed, NCS specialists are often more interested in physical parameters like critical mass or penalizing water moderation rather than the k-effective given by the code (which is often an intermediate parameter). An approach dealing with this issue is presented, using a "second level" criticality modelling, integrating statistical learning algorithm, criticality model & k-effective calculations. This approach will help NCS specialists to solve complex and time consuming NCS problems. As an illustration, practical applications like homogeneous/heterogeneous subcritical limits determination or subcriticality checking of configurations will be tested, actively involving participants.
