[1M08] Theoretical Development of Method to Estimate Reactivity and Fissile Isotope Ratio at the Same Time Based on Power Profile in Quasi Steady State
Keywords:subcritical, reactivity estaimation, fission isotope ratio, power profile, quasi steady state, TRACY
A new method has been already proposed to estimate reactivity in dollar of an amount of nuclear fuel in subcriticality based on a power profile in quasi steady state. It is theoretically expected and reported here that by applying the method to neutron count rate during several hundred seconds, fissile isotope ratio can be estimated.
