Five years is extremely optimistic.

The Finnish Olkiluoto plant might go on line in 2022 and then it would have had a 22-year development time. Starting such a project today this would mean it finishes around 2040. And this was planned with "conventional" nuclear technology and knowing well all the difficulties such a construction entails. That would perhaps be in time to power a kind of cold house museum to show our children how Earth has been looking before runaway climate change.

Proposing new technology which is sure to run longer smells to me a lot like to suggest doing nothing in order to avoid change that is both absolutely urgent, and totally possible now.
