Diverting resources from solar and wind which are growing ~25-50% and currently 2EJ/yr per year to nuclear is a net loss given that a 20 year build up of the nuclear industry resulted in <1EJ/yr increase in the 80s. By the time any new reactor is online, the annual production of new PV will exceed the entire nuclear fleet builtnover 70 years.

Just the first fuel load for that much nuclear requires more than doubling uranium mining. Not to mention the iridium, gadolinium etc. or anything outside the core. And this is in uranium resources that are significantly worse than those currently being mined.

The “so much copper” for solar is about 0.4kg/kW for distributed (10% of current mining would cover all electricity in 2 years).

Similarly current lithium production is producing about 1TWh/yr of batteries. 10 years of that is overkill for lithium’s role in grid storage (although about an order of magnitude more is needed if the goal is for everyone to have an EV and we ignore sodium ion, both unrelated to cancelling renewable projects and instead pretendingnto build a nuclear reactor).

You’re also making fossil fuels seem like a bigger contributer than they are. 1J of electricity will provide 5J of space heating or the same travel distance as 5-8J burnt to refine petrol and make an ICE car go. 20% hydro/renewables/nuclear means that only 50% of the actual stuff done is via fossil fuels. Which is not to say heat pumps and electrified transport are trivial transitions, but they are necessary either way.
