摘要

The paper deals a systematic approach of some importance problems, concerning of the conditioning the molecular sieves wastes resulted from Cernavoda Nuclear Power Plant using binder materials, ensuring the prerequisites for elaboration of the recipes of the waste forms. In order to justify the more or less different behavior of wide range of potential binder materials (high alumina cement, Type II Portland blast furnace cement, Type I normal Portland cement) in relation to the molecular sieves content, within the paper has been studied the leach rates of tritium and the compressive strengths. Moreover, the research works carried out took into consideration the determining correlations between composition-processing-proprieties covers mixing properties (workability), hardening process (setting time). Typical properties and limits of the molecular sieves waste forms could meet the Waste Acceptance Criteria of the disposal site. The experimental results suggest that, the normal Portland cement is the best binder material for immobilizing molecular sieves wastes, addition of sand and dispersed agent into matrices would greatly enhance the properties of the waste forms.
