Assuming that the price per SWU is $80 and the cost of conversion is $4/kgU, what is the price of the U3O8 in $/lbU3O8 beyond which it will cost less to enrich the already mined, purified, and converted (to UF 6 ) tails that contain 0.2% 235U rather than mine new uranium? Assume the product will be 3% enriched in U in either case and the new tails will be 0.1% (when the old tails are enriched). Tails stored as UF6 cost nothing

U- Uranium, they are all online
