Composite Material Based on Shale Phenols for Radioactive Waste Immobilization

摘要

A composite material with a cohesion strength of 2.94 MPa, an adhesion of 2.6 MPa to steel 3, and a specific elongation of 75% was prepared based on shale phenols. It was used for radioactive waste immobilization. The leachability of cesium from immobilized blocks was 1× 10~(-10) cm~2/s, which is several orders of magnitude lower than the leachability of 1×10~(-6) cm~2/s from Portland cement. The leachability of cesium from immobilized spent ion exchanger containing cesium was 1×10~(-11) cm~2/s.
