Development of a versatile plant simulation code with PC

Mochizuki, Hiroyasu

This paper describes about the development of the plant simulation code NETFLOW. The code developed to simulate thermal-hydraulics in the auxiliary cooling system of a reactor has expanded to simulate plant dynamics not only for light water reactors but also for liquid metal cooled fast reactors (LMFRs). In order to improve the applicability for LMFRs, models affecting on characteristics of natural circulation are improved. They are a model of inter-subassembly heat transfer and a model of heat transfer coefficient of finned heater tubes in an air cooler. A natural circulation in the Joyo experimental fast reactor after the reactor trip is calculated, and good agreement has been obtained between the test and simulation results.
