IIRC the idea behind BN reactors is that single such reactor would "burn" waste from 2-3 VVER reactors and recycled by BN fuel would be loaded back to them.
So you would install a number of BNs in Russia and supply recycled fuel back to exported reactors. Not only you will save money on fuel (well, assuming nuclear fuel will cost more than it does today), but also will reduce amount of nuclear waste for long-term storage (today most of waste from exported reactors has to come back to Russia).
