Wow. You got triggered hard by that. My comment was in response to the pearl clutching over the imagined requirement of Lithium mining as a component of a system that generates electricity from wind and solar.
If we take diurnal storage being provided by lithium batteries as a given, then a VRE system producing 1kW >95% of the time using existing commercial technology requires roughly 1kg of lithium in 6-12kWh of batteries which needs to be recycled or replaced every 12-20 years.
A system producing 1kW of electricity from fission 85% of the time using existing commercial technology requires fuel made from 1kg of mined Uranium. The Uranium needs replacing at least every 6 years. You can calculate this easily from burnup (25-60MWd/kg thermal), thermal efficiency (30-38%), and the Uranium required to make a unit of fuel (~8kg per kg of fuel).
Hence the pearl clutching is revealed as disingenuous nonsense and the proposed alternative to the terrors of Lithium mining is revealed to be worse, and why you are triggered.
