REACTOR REACTIVITY MEASURING METHOD

摘要

A method is provided for measuring reactor reactivity, comprising the following steps of acquiring a set of measuring data IRPN of a neutron flux level of dynamic response; an inverse dynamic calculation for measuring data IRPN of the neutron flux level based upon the point core kinetics equation, and gaining a reactivity ?m; linear fitting ?m(IRPN-?0)=f(IRPN)of IRPN dynamic response data after reactivity keeping a constant state. The slope is reactivity ?.
