ABSTRACT:
The powdered form of nuclear fuels such as uranium dioxide and plutonium dioxide are dispersed in an about 3N aqueous nitric acid solution, and irradiated by UV rays at a wavelength of approximately 300 nm in order to improve a dissolving rate of the nuclear fuels. This enables easy and efficient dissolution of the nuclear fuels.
