1. A REMIX fuel for a nuclear fuel cycle comprising a mixture of regenerated plutonium and enriched uranium in the form of oxides providing the same energy potential as a fuel from enriched natural uranium, and suitable for 100% load of a thermal neutron reactor core, characterized in that the REMIX fuel contains comprises:
from 1 to 2 wt % of plutonium dioxide obtained from reprocessing VVER spent nuclear fuel, and comprising over 51% of isotope Pu-239,
from 17 to 19 wt % of enriched natural uranium dioxide comprising 19.75% of U-235 isotope, and
from 79 to 82 wt % of regenerated uranium dioxide obtained from reprocessing of VVER spent nuclear fuel.
