No, we screwed it up so much that it would take decades to fix. Building a traditional reactor takes over ten years, while advanced reactors need ten more years of R&D. By that time, renewables may be cheaper than even next-generation reactors.
Also, all of the nuclear reactors in the world provide about 10% of the world's power. Even doubling this might not be enough.
At the same time, solar and wind provide 2.7% and 5.3% of the world's electricity (nuclear is 10.4%) - yet everyone is comfortable betting on them to solve our climate crisis.
