Minor actinide content of spent nuclear fuel dominates the long term heat load and radiotoxicity of the highly active waste after its final disposal. Currently all countries with running civilian nuclear program face the challenge of the management of spent nuclear fuel. The most secure solution seems to be the deposition of the highly radioactive waste in deep underground repositories located in a suitable geological host formation. To prevent posing a risk of releasing radionuclides into the biosphere requires a combination of engineered and geological barriers to be placed around the waste form.
