Nuclear energy is a safe, clean and cheap energy source. The establishment of the nuclear power station ought to be based on strict site survey and technical design. In this paper, the task and requirement that the remote sensing and geophysical prospecting should fulfill in various site-choosing stages for the nuclear power station have been emphatically dealt with and the idea of systematic engineering for organizing remote sensing and geophys ical work in different sitechoosing stages has been put forward on the basis of China's reality.
