“1. A method for weather modification by using a nuclear fusion reactor or a nuclear

fission reactor as a heat source, and a thermal exchanger charged with water to be

heated for vapor generation, the method comprising introducing a circulation pipe for

circulating a fluid cooling the nuclear fusion reactor or the nuclear fission reactor or a

fluid for thermal exchange in the nuclear fusion reactor or the nuclear fission reactor

into the inside of the thermal exchanger to put the fluid in contact with the water to be

heated to generate vapor, jetting the vapor at a state of collimation prepared with a

vapor discharge pipe into the sky, and forming a cloud in the sky with the jetted vapor

for blocking sunlight so as to reduce the temperature on the surface of the earth.”
