Device for the storage or disposal of radioactive wastes

摘要

A container for the ultimate disposal of radioactive wastes comprises an outer receptacle of standard size and interchangeable inner receptacles receivable in the outer receptacle and provided with spacers for centering the inner receptacle within the outer receptacle. For radioactive waste with reduced radioactivity, a larger receptacle containing a larger quantity of the waste can be disposed within the outer receptacle whereas, for more highly radioactive waste, a smaller receptacle containing smaller quantities of the radioactive waste can be disposed within the outer receptacle. The space between the two receptacles is filled with a substance capable of absorbing radiation from the inner receptacle, i.e. a radiation absorber or shielding material.
