EVALUATION OF FEEDBACK REACTIVITY COEFFICIENTS BY INVERSE KINETICS IN MONJU

摘要

The feedback reactivity measurement was conducted in the Monju Core Confirmation Test in 2010. Two reactivity parameters related either to power and to the core inlet coolant temperature were evaluated within 5% accuracy based on the reactivity measured with the inverse kinetics technique. We confirmed that this advanced method is applicable to the fast reactor operation and shorten the duration of the experiment for the feedback coefficients evaluation.
