New suggestion:
Make the recipe: 2x 'Depleted uranium metal mixture' > 2x 'Depleted uranium ingot' available in the Space-Age Foundry.
The sheer speed (and modules), and the prod bonus will be really nice without it being overpowered, every other item that uses the ingots as an ingredient still needs another radioactive element anyway, or in the subsequent recipe. No overpowered bonuses for anything concerning nuclear power generation.
The real bonus wouldn't be nuclear power but depleted uranium ammunition types, which is fair in my opinion. Plus the convenience of smelting everything on site.
