"economically viable" what is the price target here? If it is 2022 solar and wind LCOE cost, and you are targetting, say, 20 years to build a plant, then those aren't viable targets. Solar and wind will probably drop another 50% or more by then in LCOE cost. It's worth research, sure. But the same issues of new-gen nuclear are shared with any fusion, except fusion is way further down the prototype stage. Solar/Wind/Battery is already near-price competitive with natural gas turbine unsubsidized (and they never seem to account for all the hidden fossil fuel subsidies), and the curves are still in prime economies of scale improvement.
