EPR of radiation-induced paramagnetic centers in irradiated sodium silicate glass for immobilization of solid radioactive wastes synthesized in various conditions

Joining of Materials


The nature of radiation-induced paramagnetic centers (RPC) in glassy materials produced at vitrification of solid radioactive waste (SRW) surrogates with sodium silicate fluxes at the silicate modulus values of 2, 3, and 4 depending on the SRW oxide loading and the preparation method was studied. The connection between the type of RPC formed at silicon-oxygen units of the glass network and chemical durability of the glassy materials was established.
