Instrumentation Concept for Core Surveillance of Pressurised Water Reactors

摘要

Starting from the core monitoring concept and the characteristic parameters determining the integrity of the reactor core, the instrumentation concept for core surveillance of PWR's of the 1300 MW class will be presented. The out-of-core and in-core instrumentation is illustrated in more detail and reference is made to the test equipment for control rod position, boron concentration, coolant pressure, coolant temperature and coolant flow. The information provided by these measuring systems is used for protection, limiting and operating systems. Because of similar requirements and the physical situation, comparable concepts are implemented in KWU and BBR reactors. (ERA citation 10:020531)
