Abstract
Since the first nuclear power generation of 5 megawatt was Started at the Japen Atomic Energy Institute in October, 1963, its development work has been growing steadily as to be able to make a plam for the installation of a power station with a capacity of 600-700MW in the near future. It is anticipated that in ten years onethird of an increasing electricity will be shared by the nuclear power. It is estimated that cost of electricity produced will be 2 yen/kWh with a power station capacity of 600MW, which is well economically competitive with thermal (oil) power at that time in our country. The author further explains the principie of the nuclear power generation together with its safety problem. The present atomic industry in this country is greatly dependent on the techniques developed in foreign countries. However, in view of the fact that the nuclear power generation is coming near to practical use, the emphaseizes the home production of power plants as well as the development of new type reactors, especially fast reactors should be progressed enough to establish Japan's own nuclear industry.
