摘要
Abstract
In the measurement of reactivity ,disturbance currents such as γbackground , electrical noise and neutron source currents take a significant fraction in the measured signal ,resulting in a large error to the measured reactivity .In this paper ,the impacts of background and source currents on the reactivity measurement were described ,and the dual fitting method ,a self‐developed method on the correction of background and source currents ,was introduced .The method was used in the dynamic rod worth measure‐ments in a test reactor and satisfactory results were obtained .关键词
