I am not sure if I understand your comment lol

I could also say: Solar is the best energy source (if you put night aside of course).

I mean obviously the main drawback of nuclear fission is the waste and the potential impact of radioactivity.

No, the main drawback of nuclear is it costs too much.

If nuclear were just as expensive as it is now but had no waste or radioactivity it would still be struggling.

If it were 10x cheaper but still had the waste and radioactivity it would be going like gangbusters.

    Perhaps. While the amortisation of the costs of Chernobyl etc. over the global nuclear fleet are surprisingly low, the local economic impact was high enough that even governments are cautious about the risks.

    e.g. the Chernobyl exclusion zone is about the size of Luxembourg, so I'd expect their government to have had… discussions… with the French government about the safety of the nearby reactor in Cattenom: were it to détoner while the wind was blowing the wrong way, Luxembourg may cease to exist.

    (Low risk, but existential if it happens. Not everyone's as enthusiastic as powerful people seem to be today about AI).

  • To be fair nuclear is as expensive as it is mostly because of radioactivity. There'd be no need for all the heavy concrete, armed guards, and spent fuel disposal if the materials were innocuous.

I don't believe the parent commenter was setting aside the waste and potential impact of radioactivity as the risks associated with those are very very low. I think they were setting aside the literal mining and handling of the raw material before it even enters a reactor which is fair IMO. Also uranium mining is more often happening with in situ leach mining which removes a lot of the risk and environmental impact [1] - especially compared to lithium extraction!

Also to clarify, modern Gen III+ reactors have passive safety systems that make leaks/meltdowns virtually impossible [2], and the total volume of high-level waste is tiny, solid, and completely contained in dry casks with little chance of escape - however there are some concerns on the 100+ year timescale, I'll admit.

Also a fun fact, deaths per unit of energy of nuclear compared to solar are nearly identical.[3]
