The 10-point plan proposes a fleet of small reactors based on the old technology that produces long term nuclear waste. It would be far better to go straight for safer Molten Salt thermal generators, that produce no long term waste, ideally powered by thorium rather than uranium. You could replace all the aging Nuclear plants with Molten Salt generators burning up the old nuclear waste, and all old fossil-fuelled power stations with replacements powered by the far safer thorium.
The new power plants should all be dual-tap, producing electricity as required, but using the surplus heat directly to run other useful processes. Examples include zero-carbon production of hydrogen, or the hydroxide-based atmospheric CO2 capture process or any other chemical process requiring heat – metal smelting, fertiliser production, cement manufacture, etc.
The electrical output can be varied to balance shortages between the renewable production and demand, thus making the grid more stable without needing to burn natural gas.
