Résumé

In 2005-2006, a series of experiments referred to as BFS/MOX was conducted at the BFS-1 experimental facility in IPPE, Russia. The program was designed to provide a basis for validation of criticality calculations for MOX fuel manufacturing processes and particularly with low-moderated MOX fissile media. The extensive experimental program was performed on those configurations, including criticality and reactor-type parameters measurements. The experiments were evaluated, peer reviewed, and analyzed with various codes and cross-section data. Criticality validation study was performed employing sensitivity/uncertainty technique based on the generalized linear least square method. The paper illustrates different tools' performance when calculating criticality for the BFS/MOX configurations and focused upon the validation process and results for generic application systems with weapons-grade plutonium.
