I think those numbers unfairly assume many things, including: - breeder reactors will not exist in time - we will not find more uranium on Earth than we have already - we will not be able to economically extract uranium from seawater, phosphate minerals, coal fly ash or other sources - other materials besides uranium will not be used in the future - synthetic production will not become viable To say that nothing will change in the next 40-70 years and we will simply run out of material and stop using nuclear altogether, just seems quite far-fetched in my opinion.
