Disposal of radiation waste in glacial ice

A spherical radiation waste container for use in storage of fission products, separated from actinides in deep permanent ice, comprising:

• a spherical corrosion resistant container having a core filled with said fission products separated from actinides initially mixed with said fission products, and said fission products consisting essentially of Sr-90, Cs-137 as the dominant fission products,
• said fission products being in a metal matrix of spherical configuration to successfully encapsulate and store said fission products,
• said core and said metal matrix being dimensionally configured to define a waste container such that the radiation outside the waste container does not exceed human safety limits and such that the container surface reaches a temperature sufficiently high to melt ice, but not cause corrosion of the container surface, nor render the temperature at the center too high, and in manner wherein the time taken to reach the bottom of the said permanent ice, such as the Greenland icecap, is of the order of 7 years.
