ABSTRACT
Nuclear spent fuel waste management using ion beam injection has been investigated. Ion beam injection can make the form of the container for the nuclear waste safer for the proposed radiation. The investigation is performed at the nanoscale level. The computer simulation can predict the reliability of the industrial application in several outputs such as ion distribution, range, ionization, phonons, recoiled energy, and whether there will be a damage event. Currently, it is very dif•cult to •nd a nuclear waste repository site for permanent waste disposal in some countries including the United States. Therefore, it is important to make a strong container material for nuclear waste radiation shielding for the interim period until a repository can be selected and agreed upon by the community and the government. Nuclear waste containers should provide protective barriers against physical and chemical stresses during transportation, interim storage, and disposal. In the case of high-level waste (HLW), separated casks are used for transportation, and special emphasis is given to the disposal containers to ensure longterm isolation of the waste. The key performance parameter is the resistance to environmental attack (chemical performance). Mechanical performances, thermal/neutronic performance, compatibility with other materials, fabricability, and previous experience, as well as cost, are also taken into account (McCright 1991).
