Abstract

Abstract

As the main sub-system of Monitoring,Control and Diagnostic System for Tianwan NPS,In-Core Instrumentation System carries out the function of calculating and monitoring the real-time parameters of the reactor during normal operation and transient condition.For the first time,linear power rate of fuel rods and DNBR are used as on-line safety protection signals to ensure the safety and economical operation of the reactor.
