The cost of power from nuclear is quite competitive. Capital costs are high but, like renewables, amortized over a long lifetime with low operational costs. Your wiki link puts nuclear cheaper than solar or offshore wind, and barely more expensive than onshore wind.
Moving to small modular reactors, as many outfits are trying to do, will lower the required investment and time to production. Liquid thorium or fast uranium would largely eliminate long-term storage problem...in fact, we'd eliminate the long-lived wastes we have right now. (In the meantime we should keep wastes in a form we can use for fuel later.)
Renewables are great as far as they go, but there are only so many places you can build a good dam, and wind needs either a large oversupply, an economical energy storage system (which, other than the limited hydro, doesn't exist), a drastically souped-up and expensive power grid, or possibly all three. You don't have to worry about that if you're just adding power on the margins, but you do if you want to run civilization carbon-free. Taking all that into account, it's questionable whether wind would really be cheaper, especially as we're forced to expand into less suitable locations.
