Is Russia in Control of the Uranium Market?

If russia and china jointly decided that they wanted to withhold uranium from the west as a form of economic warfare, are they in a position to do that? And how long would it take before the west ran out a fuel for their nuclear power plants and had to shut them down? So neither china nor russia mine. Russia mines, i believe, around five or six % of the world's raw uranium. The ures still gets about a quarter of their enrich geranium product from rosan. But where the real pinch point, as mike pointed out, is in the enrichment sphere.
