Absolutely, the key phrase is "current usage and reserves". There will almost certainly be ways developed to stretch or augment or displace uranium as a nuclear fuel. Thorium salt reactors look promising. But unfortunately there has been lack of political will to fund research and it's only recently that its being investigated seriously again. And this is a common story with virtually all the interesting nuclear technologies. Sounds great, but who's paying for the fundamental research? My point is that people often compare nuclear and coal as if radioactive ore - which today does mean uranium - is some infinite resource, just because it isn't made of fossils. The idea of "oh well, we'll just mine more as it gets economic to do so" isn't a sustainable solution to clean energy.
