Abstract: Based on the practice of the construction of the supervisory monitoring system of a nuclear power plant and the experience feedback of other nuclear power plants, this paper analyzes and discusses the key issues which are easy to be neglected in the process of site selection and scheme design of the system, and puts forward relevant suggestions, which can be used as reference for the relevant work of nuclear power plants.Based on the construction practice of a certain nuclear power plant supervisory monitoring system, and referring to the experience feedback of other nuclear power plants, we analyze and discusse the key issues which are easy to be neglected , and need to be paid attention to, in the process of site selection and scheme design of the system. We then put forward relevant suggestions, which can be used as a reference for other nuclear power plants to carry out the similar work.

Key words: Nuclear power station, Radiation monitoring, Supervisory monitoring system
