Whole-plant simulation for loop-type LMFBR dynamics

A loop-type LMFBR of prototype plant is going to be developed in Japan. The whole-plant dynamic simulation program COPD (Code on Plant Dynamics) performs the basic tool of the characteristics analysis for control system design, evaluations of thermo-hydrodynamics for setting the design condition of components and accident analysis for explaining the validity of the reactor shutdown system of the plant. This paper describes the specifications of the model adapted to typical analysis items, verification of the model with the experimental results, reduction manner of the running cost and model improvement of the COPD program
