At the most generous calculation that puts nuclear power at 5 x more expensive that solar PV. So if you have a theoretical pure electricity bill on solar PV of $100/month, your theoretical pure electricity bill on nuclear of $500/month.
I’m not sure how you reach the conclusion that nuclear is not significantly more expensive.
I’m looking at that source it shows:
