https://en.wikipedia.org/wiki/Uranium_ore
Each installed gigawatt of nuclear reactor power, regardless of whether this is twenty 50MW reactors or a single 1000MW reactor, requires on the order of 200 tons of uranium fuel rods per year to operate. By comparison, a 1GW bituminous coal plant burns on the order of 2,750,000 tons of coal per year to achieve the same kind of baseload power output.
However, coal requires no further processing once mined. To get those 200 tons of fuel rods, it can take a varying amount of uranium ore, and the majority of that ore is not high-grade, it's down around 0.1% U3O8 more often than not (there are a few high-grade deposits). So you might have to mine 200,000 tons of ore, extract the uranium in the form of yellowcake, convert that to uranium hexaflouride gas for enrichment from ~0.7% to (apparently) 4.95% for the NuScale design, and then convert the gas to solid uranium oxide and package it in a fuel rod. This is a pretty intensive industrial process just to make the required fuel and is neither cheap nor all that clean.

If you are in a location with plenty of sunlight and wind, I don't see how this could possibly by less expensive than some kind of integrated wind turbine/solar PV/solar thermal linked-to-storage grid of the same capacity.
