There is no way nuclear power has an ERoEI anywhere close to oil. I have seen numbers like this before and they always use outdated data like assuming the uranium enrichment is done with processes basically no one uses anymore. Nuclear has an ERoEI larger than anything else out there. Just as an example of the difference modern enrichment processes make just look at Tricastin Nuclear Power Plant in France. They used to use 3x 915 MWe nuclear reactors just to power the gas diffusion uranium enrichment process to produce fuel for all French nuclear reactors (several dozen). The replacement gas centrifuges uranium enrichment process uses 50x less power which means 2700 MWe have been put back into the electric grid. i.e. it used to take 2745 MWe to enrich the uranium fuel for all those reactors and now it takes 45 MWe. That is just one example of the difference modern nuclear technologies make and this is something that is in commercial use today. Not a prototype. Centrifuge technology is used in Russia, China, France, and the Netherlands to produce all their nuclear fuel for example. Plus a lot of their production is exported to places like Japan or the USA.
It is even possible to increase performance of that further with laser separation. Plus like we talked about before there is work being done on fast nuclear reactors which will reduce the need for enrichment and enable to both increase the rate of burn of existing fuel and to use increase use of U-238 as fuel further decreasing fuel costs. Fast reactors can burn what is currently either classified as tailings or waste into energy.
We could power all our current consumption of a couple of centuries on coal alone. Several centuries or thousands of years on nuclear alone.
