... there are somethings that are often left out of the pricing

Another example that gets skimmed over or ignored is the massive cost of decommissioning a nuclear power plant. It typically ranges from $280 million to $2 billion, depending on the technology used. More complex plants can be up to $4 billion. And the process can take 15 to 30 years to complete.

there is some nuclear tech that can use nuclear waste as at least part of it’s fuel

Those are less competitive, and salt reactor attempts have historically caused terminating corrosion problems. The SMR "promise" relies on switching extremely expensive/rare/dangerous plutonium level enriched fuel, that rely on traditional reactors for enrichment, for slightly lower capital costs.

Not an expert, but molten salt reactors are correct. MSRs are especially useful as breeder reactors, since they can actually reinvigorate older, spent fuel using more common isotopes. Thorium in particular is useful here. Waste has also been largely reduced with the better efficiency of modern reactors.

Currently, Canada's investing in a number of small modular reactors to improve power generation capacity without the need to establish entire new nuclear zones and helps take some of the stress off the aging CANDU reactors. These in particular take advantage of the spent fuel and thorium rather than the very expensive and hard to find Uranium more typically used. There's been interest in these elsewhere too, but considering how little waste is produced by modern reactors, and the capacity for re-use, it feels pike a very good way to supplement additional wind and solar energy sources.
