This study presents a probabilistic approach for solving burnup problems in nuclear transmutations, offering a new method free from the challenges of traditional approaches. It includes an introduction to burnup equations, outlines of the methodology, and the probabilistic method's mathematical form

A comprehensive overview of reactivity trends in ENDF/B-VIII.0 due to uranium cross-sections and burnup, highlighting differences from ENDF/B-VII.1. Focus areas include loss of reactivity in PWRs, discrepancies in individual nuclide substitution, and updates in U-235 evaluation. Notable changes in U

When a non-stationary reactor is shut down or its load is reduced to zero, xenon poisoning occurs due to the disruption of dynamic equilibrium between the increase and decrease of 135Xe. This leads to a temporary increase in 135Xe concentration, followed by a decrease as it decays. The reactivity ma
