Method for preparing granite-based high-level waste solidified body by using laser

The invention discloses a method for preparing a granite-based high-level waste solidified body by using laser, which comprises the following steps: S1, grinding and uniformly mixing high-level waste powder and granite powder to obtain uniformly dried mixed powder; s2, the mixed powder is put into a crucible mold, then laser sintering operation is conducted on the mixed powder in the crucible mold through a laser device, and a high-level waste solidified body is obtained; and S3, the high-level waste solidified body is cooled, and then the high-level waste solidified body is separated from the crucible mold. The granite-based high-level radioactive waste solidified body is prepared through laser, the advantages of being efficient, convenient to use and the like are achieved, rapid heating can be achieved through the laser device, the complex high-level radioactive waste can be effectively solidified, the solid solution amount of the complex waste can be effectively increased, and the volatilization amount of
