Rhodium self-powered neutron detectors are utilized in many pressurized water reactors to determine the neutronic behaviour within the core. In order to compensate for the inherent time delay associated with the response of these detectors, a dynamic compensation algorithm is currently used in Combustion Engineering plants to reconstruct the dynamic flux signal which is being sensed by the rhodium detectors. This paper describes a new dynamic compensation algorithm, based on Kalman filtering, which improves on the noise gain and response time characteristics of the algorithm currently used, and offers the possibility of significantly expanding the capabilities of the present in-core detector system without a major hardware investment.
