A Microprocessor-Based Four-Section Excore Detector System

The advent of microprocessors has added a new dimension to process measurement and control. Nuclear instrumentation has not been excluded. One system which has recently been introduced is an out-of-core detector system. This system provides continuous monitoring of the axial power distribution using four-section excore detectors. The microprocessor allows the system to be self-contained and provides the functions of data collection and analysis not possible through analog techniques. The hardware and software developed to achieve an intelligent monitoring system is presented.
