Please stop. The raw materials for any type of nuclear reactor are vastly scarcer than renewables.
Iron flow batteries exist at grid scale for $200/kWh (enough to beat nuclear total system cost where 90% of people live with higher uptime) and dropping.
Copper metallized PV uses a manageable amount of copper and nickel (100s of kgs per MW net) and less silver than the control rods in a fission reactor. The dopants are measured in mg per MW and the rest is fancy sand. Inverters tend to be GaAs, but the amount is minimal and they don't need high performance power electronics to outperform nuclear.
Multi megawatt wind turbines with no copper windings and no permanent magnets exist at commercial scale, and all Aluminum cabling is ready as a dropin replacement as soon as the few dollars per MWh maintenance burden can he justified. Concrete and steel per MW is still significantly higher for wind, but a mix is approaching parity.

It really isn't. Helion is a moonshot that might work (but requires large amounts of rare metals for exotic superconductors). Anything thermal will be 10s of times more expensive and more materials than fission.
