Monazite (thorium and rare earth orthophosphate available in the Near South Bug river region, Ukraine) is considered as raw material for production of 208Pb lead isotope, advanced liquid metal coolant for nuclear systems, because of low neutron capture cross-section. The total resources of monazite are estimated as 0.5·106 ton. The estimated operating cost of monazite lead production is $ 30 USA/kg. It is also possible to extract monazite from titanium-zircon deposits of Ukraine. However, in this case, 208Pb purity would be low.
