EPOXY COMPOUNDS FOR IMMOBILIZING RADIOACTIVE WASTES

摘要

The radiation resistance of epoxy compounds, solidified by crystalline hardening agents - metaphenyl-enediamine and phthalic anhydride - is investigated. It is shown that under conditions of γ irradiation (E = 1.33 MeV) the temperature of vitrification of the compounds depends on the dose (doses up to 1500 Mrad were investigated) and temperature 20-160℃, and the radiation gas release depends on the vitrification temperature and irradiation. It is shown that epoxy-phthalic anhydride compound is best as a matrix for immobilizing solid radioactive wastes at high temperatures (80—130℃). The experiments showed that the proposed compound can be recommended for immobilizing solid radioactive wastes.
