Instrument Failure Detection Using Functional Redundancy Applied to a Nuclear Pressurizer

摘要

The reliability of instrumentation in a nuclear power plant is critical. Designers, analysts, and ultimately the operators must rely upon the instrument readings in order to maintain safe and economical operation of such a complex system. The accident at Three Mile Island illustrated further the importance both of correct instrumentation, and the interpretation of the information provided by the instrumentation. The work presented in this thesis represents an effort to improve the reliability of the instrumentation in a nuclear power system by detecting instrument failures. This is done using the functional or analytical redundancy available in the system. (ERA citation 06:020197)
