A code known as MRCPRS is developed using the FORTRAN?77 language. It is a general safety analysis program with the module structure character and can be executed by using the micro computer. MRCPRS divides the core into three regions in the radial direction, and six control volumes in the axial direction. The numbers of control volume can be changed according to the user’s requirement. The fuel element could be the round or plate shaped as selected by user. The steady state and different transient conditions of the core are studied and tested using the code with two different algorithms. They are the Gear and Adams method. The results show that MRCPRS can be used to address the safety of PWR core.
