The amount of fuel that you're quoting assumes that we don't ever reprocess the spent fuel. While the US doesn't do this due to proliferation concerns, it's possible to dramatically increase the longevity of nuclear power by doing so. This is likely what Oklo is doing. All we need are a couple of centuries to develop better technology than nuclear. We don't need it forever. It buys us time until we can develop storage and eliminate the need for fueled baseload power entirely.
