REACTOR CONTROL SYSTEMS BASED ON COUNTING AND CAMPBELLING TECHNIQUES FULL-RANGE INSTRUMENTATION DEVELOPMENT PROGRAM

摘要

The objective of Project Agreement 22 was to determine the feasibility of covering the complete reactor neutron flux range from 1 × 103 to 5 × 1013 nv in-core by using in-core or out-of-core ion chambers.nThis report describes the analytical predictions and the experimental results of a nuclear instrumentation development program undertaken by General Electric to determine the feasibility of this approach. The program has been concerned with the development of a full-range reactor control system incorporating either in-core or out-of-core ion chambers, and the purpose of the program has been satisfied by the development of a full-range instrumentation system consisting of two electronics subsystems. Counting techniques are utilized for source and lower intermediate range neutron fluxes, and Campbell - or mean-square voltage - techniques are utilized for inter mediate and power range fluxes.
