The Oil Drum

The Japanese research group's work doesn't appear to
require intensive amounts of input energy, like fossil
fuel, as opposed to e.g. corn-based ethanol.

It is a complex inorganic chemistry adsorption tecnnology, and is reusable. It is uranium fishing (dip in seawater, wait, pull out), not distillation.

I doubt it will be necessary---there is a current enormous boom in uranium exploration and mine development. I suspect the figures in the original post of uranium reserves available at a given price are highly underestimated.

Uranium exploration is not remotely as deep and comprehensive as petroleum exploration.

And then, there are fast neutron fuel cycles which let one use the enormous amount of depleted U-238 currently sitting around in dumps.

Perhaps there are other non-fossil technologies which in the future will be economical for baseload electricity generation---that's wonderful.

I believe that it's important to look not just at the marginal cost (c/kWh) but total capacity availability as well. Nearly all of the geophysically sensitive methods, e.g. wind, solar and geothermal, have strong siting restrictions, in aggregate worse than nuclear plants. This means that there are diseconomies of scale.

I believe that maximum effort in both nuclear and non-nuclear sources of non-fossil electricity is imperative.

If we go entirely by hypothetical economic computations, the answer comes out to be not stored solar or wind, but cheap coal, which will ALWAYS be cheaper than anything else for 3 centuries, without external regulation.

It isn't solar versus nuclear, it's solar & nuclear etc versus coal.
