So with the largest single deposit in Australia, and with Canada the largest producer, that must mean the the present administration in Britain considers those "friendly countries?" (And that the friendship is stable?)

An advantage sometimes claimed for nuclear power is that once a sufficient quantity of material is assembled to start the production of power, breeder methods can be used to minimize the requirement for a continuous input of fuel. This could have the effect of stabilizing the cost of production, and making it more reliably predictable over a mid-range term of a decade or two, perhaps a little longer.

With fossil fuels especially, there seem to be constant perturbations in the cost of maintaining the continuous flow of fuel.
