Extremely.

Using extremely generous assumptions about high grade ore, and old, much simpler reactors you can come in slightly under that for about a month.

EROI is significantly worse than solar because of ongoing energy costs for fuel and O&M. Especially if you use ore that is typical rather than the low hanging fruit. A perc module is around 60-120 depending on where it is placed. NPP is 15-60 depending on where its uranium comes from, how it is enriched and whether it uses reprocessing.
>> Mining: Ranger ore in 2008 was 0.26% U head grade. Energy: 273 GJ/t U3O8, 322 GJ/tU, including significant development work. (Note that if ore of 0.01% U is envisaged, this would give 1638 TJ/yr, 70 PJ total for mining & milling, hence total 108 PJ for the centrifuge option, thus inputs become 3.3% of output and energy ratio becomes 30.) All Ranger inputs are thermal (it generates own electricity). The Schneider 2010 figure for mining & milling is similar to Rössing.
> ??? if things actually do become expensive, welcome to breeder reactors bro
You can't start a breeder reactor without fissile material so new capacity still needs just as much (they don't exist so can't say for sure, but about double per GW by fairly generous estimates, actually). Additionally most of the concepts need about 2-10% of annual Beryllium production per reactor.
You have to fit something into the industrial capacity of the world before you can start gaslighting about costs that consistently go up or about costs of technologies that don't exist and might maybe start figuring out the hard bit of extraction and refuelling in ten years.
Expanding Uranium mining 5x would require processing a billion tonnes of ore per year. For reference Iron Ore production is about 2.5 billion tonnes. You'd need at least 30 million tonnes of sulfuric acid (world production is about 180 million).
Then for the reactors you'd need the most of the world supply of chromium. For a PWR you'd need half of the indium, and significant amounts of Zirconium, Cadmium and silver. Reliable Molten salt reactors don't exist and there's one MSR with okay capacity factor, but no information about how kuch noble metal they need is available.
This is just to match renewables now mind you, not where they will be when you finally open your mines (which takes years or decades).
The idea that Nuclear could scale to match renewables in under 50 years is laughable. Which is why fossil fuel shills butt into every conversation to claim renewables can't work and must be replaced with it.
