Uranium is 9% of the cost to generate power in a fission plant. Turbines, containment, staff and maintenance make up 91% of the cost. Deuterium/Tritium fusion will produce significant neutron Flux which will require similar shielding to fission facilities (though to be fair less long term waste storage).

Even if it makes more heat you'll just need more turbines, tubing etc etc on the heat engine side.

Fission is costing 5x the cost of new solar and wind installs.

I don't see how this helps energy infrastructure and seems like it will be great for space or defense applications but the "future of limitless free power" seems to be overselling it (btw we did the same thing with fission in the 50s).
