Cost-effective, safe, and efficient technology for obtaining powder compositions of polydisperse iron oxides with carbon by reducing nanosized raw material with solid carbon has been developed. The use of the powder composition as a nonseparable activator of cementation of high-salt boron-containing liquid radioactive waste (LRW) from a nuclear power plant (NPP) instead of the previously used powder containing nanoscale iron reduces the setting time of the compounds from 56 to 2 days, reduces the volume of conditioned LRW 3–5 times, reduces the technological cycle of the waste disposal, and improves the strength characteristics of hardened cement compounds; this makes the recycling process more cost-effective.
