Material composition of the low level radioactive solid waste

The survey of material composition of the low level radioactive solid waste was performed in connection with the design work of the new incinerator in Tokai Establishment, JAERi. Five large facilities were selected as the representation of more than 20 facilities, and 500 packages were chosen out of 2,189 packages discharged during 2 months, June and July 1973. They consisted of the combustible and compressible waste but not included filters and contaminated equipments. The survey showed following result; plastics 33%, waste cloth 24%, paper 18%, rubber 9%, clothes 5%, timber 1% (total of above mentioned materials 89%), metal 7%, glass 2%, concrete and sand 2%. Eighty-nine % of the total quantity is combustible material in principle, then it will be expected that the incineration treatment get a wider application to reduce the volume of final disposal.
