Concrete conditioners for low-intermediate level nuclear wastes

Miscellaneous:

Abstract

An effort is made to provide the disposal conditioning of low-intermediate level wastes in Brazil with concrete packages designed in such a way that, in spite of being destined to receive compacted materials in long term sub-surface disposal, they may also be able to attend other storage or disposal necessities. In this way, one develops the design of a reinforced concrete package with a net volume and interior diameter adequate to the containment of pressed 200l drums. It is believed that pressing of commercial drums is an important point for simplification and cost reduction of the overall procedure. To provide flexibility in the use of these reinforced concrete packages even in marine disposal conditions, the construction specifications follow severe prescriptions to reduce corrosion and leakage. In sequence, a study is made on the comparison of 200 l steel packages. One adapts a 25 MN capacity press for this purpose and one executes two series of tests to verify the reliable volume reduction and the final dimensions and density of the compacted elements. Conclusions are reached toward a final configuration to the reinforced concrete package and the most convenient conditions for pressing. (author).
