>they never mention the word waste once when it comes to the cost calculation

Because they don't need to. Power generation plants of any reasonably modern design don't generate lots of waste, just spent fuel rods that can be reprocessed and a tiny amount of non reusable radioactive material that needs to be stored until it's less radioactive.

All the mess regarding storage sites like Yucca Mountain relates to waste from bomb production, not from power plants.

Even if we had a storage facility like that operating in the US, spent fuel assemblies from power plants wouldn't be permanently interred there, that would be a waste.
