The Russian BN-600 fast breeder reactor uses uranium oxide fuel, some enriched to over 20%, and the sodium coolant delivers 550°C at little more than atmospheric pressure. Russia plans to reconfigure the BN-600 to burn the plutonium from its military stockpiles and extend its life beyond the 30 year design span.
India has started construction of a 500 MWe prototype fast breeder reactor (PFBR) at Kalpakkam fuelled with uranium-plutonium oxide (the reactor-grade Pu coming from its existing PHWRs)
Both Russian and Indian FBR have exactly same technology.
Noone said that Indian missiles came from Russia ( and Soviet Union), until by a slip of tongue Narasimha Rao in the Parliament said that it has started coming from the Soviet Union since 1989.
