Abstract: Nuclear waste in Iraq has three major sources; spent nuclear fuel from the old Iraqi Atomic Energy Organization in Al-Twitha site, waste from radioactive isotopes used in medicine and waste generated by the nuclear weapons used in the war against Iraq in 2003. These wastes need for storage until becoming safety. Therefore, in this study nuclear waste (cerium oxides) were stored by vitrification methods in two types of phosphate glass (glass and glass-ceramics) and the effect of neutron on the immobilized waste was done. Then the physical, chemical and mechanical properties phosphate glass contain cerium oxide before and after irradiated were investigated. It found that the physical properties and the leaching was not affected by irradiation while the values of surface strength and micro hardness of glass increased with increasing radiation doses and their values have remained constant in the glass-ceramics.
