Furthermore, maintaining and controlling nuclear reactor operation are high priorities due to safety reasons. The aim of this paper is to describe the secondary system of Pressurized Water Reactor (PWR) system by using graph. Furthermore, fuzzy graph is used in performing a new graph based on its dynamicity. Finally, the results between crisp and fuzzy graph of the system are compared and verified against published data. The fuzzy graph of a secondary system of pressurized water reactor is better than a crisp graph of the system.
