REMIX - FUEL FOR A NUCLEAR FUEL CYCLE

The invention is included in the field of nuclear technologies, in particular, to oxide uranium-plutonium nuclear fuel of NPPs with thermal neutron reactors. The technical result of the invention is development of REMIX type fuel composition that enables involvement of nuclear fissionable materials recovered from SNF into NFC with simultaneous use of enriched natural uranium, and also solves objectives of recycling a separate plutonium extracted previously (including weapon-grade plutonium), reduction of SNF quantity with recycling of fissionable materials from SNF for the period of nuclear reactor operation (up to 5 recycles), natural uranium savings for fuel manufacturing, and ensuring NFC self-sufficiency as a result. The invention recovered uranium and plutonium in REMIX fuel makes it possible to use REMIX fuel to solve the entire spectrum of objectives that may be set before the closed NFC with account of the quantity of reactors, availability of natural uranium, quantity of accumulated SNF.
