Abstract

Three aspects of radiation effects regarding the repository storage of nuclear waste materials are discussed. The effects of self-radiation damage result in swelling and enhanced leaching of the host material for the radioactive wastes. The effects are minimal in glasses but more pronounced in crystalline waste forms. Groundwaters exposed to radiation will, as a result of radiolysis, form free radicals and molecular species that can alter the repository environment and, under certain conditions, may enhance the release of radionuclides from the repository. In a salt repository, gamma radiation can lead to the formation of colloidal sodium metal and free chlorine in the crystalline salt, which may also alter the repository environment upon dissolution.
