The Simulation of Reactor Physics Test for the Research Reactor HANARO

다국어 초록 (Multilingual Abstract)

The paper describes the development of a reactor power control algorithm using the program simulator for the simulation of dynamic behavior of a nuclear reactor. Before the full development of the algorithm for the commercial nuclear power plant, the Korean research reactor HANARO was chosen as a sample reactor for the simulation and for the reactor physics test. All the dynamic characteristics of HANARO were mathematically modeled into a computer program and the parameters of the plant components and the algorithm of reactor control system are adjusted to improve the transient performances as well as to satisfy the constraints imposed on the plant. Several physics parameters such as control rod worth, isothermal temperature defect, and power defec are correlated. These parameters were measured in serial order at the same core condition. The transient response of the plant shows satisfactory behavior and are well corresponding to the result of reactor physics test.
