SIMULATION OF TRANSIENT IN NUCLEAR POWER PLANT UNDER DISTURBANCE CONDITION

Abstract

It is well known fact that the fission products inside the reactor constitute a potential source of radiation hazard. Any abnormality in normal operating conditions of the nuclear power plant can lead to severe radioactive accident in the plant. One of such situation may occur when there is transient flowing in the system connecting nuclear power plant to the grid or load center. In case transient become high, this can led to immediate shutdown of reactor. If there is any malfunction of component in shutdown procedure of the reactor, then it can led to the severe accident with all radioactive material spread in the environment. So to prevent such condition, it is necessary that the behavior of the nuclear power plant under transient condition is studied. In this work we are going to do the same, which is to develop the model of nuclear power plant and then to simulate the effect of disturbance in the system so that the transient flowing in the system due to disturbance can be studied. This helps us to understand the behavior of the system.
