Analog Signal Processor and Display for Reactor Systems with Discrete Measurements

An electronic signal processor is described which, in general, may be applied to approximate a distributed variable from discrete measurements. The processor also determines the optimum location for the discrete measurement transducers which results in the best approximation to the distributed variable. A particular application is presented which demonstrates how the processor may be applied to determine an in-core neutron flux distribution from in-core detectors located within the core of a Pressurized Water Reactor.
