The parent is pointing out, that if you are trying to find a solution to generate 5kw of constant power using nuclear, for the same cost you can get an absurd amount of renewable generation and storage plus a backup generator. The batteries can store 15 hours worth of energy at peak demand, you get a 10x overbuild of peak capacity in solar, plus wind, biogas and a backup generator to boot. It is highly unlikely that the system would ever fail. I would guess you could probably cut the system size in half and still have uptime in the high 9's. And the added bonus is you would have a fair bit of redundancy should any part of the system need maintenance, whereas the nuclear solution doesn't even come with a backup generator.
