I once found out mining deaths plausibly caused by health impact of uranium mining in one region I could find data for (the Grants Mining District), and just this figure, after translating the total uranium mined into energy equivalent in contemporary reactors, was appreciably higher that what you're citing, even without counting any other mining accidents, or accidents in the rest of the nuclear industry after mining. So I remain a bit skeptical about that. (But nevertheless it was still low enough to be worth it, especially of course compared to anything coal-based.)
