As has been pointed out innumerable times, China is basically building out solar at a rate equal to five nuclear plants every two weeks.
IOW, they are building nuclear, but nowhere close to the same scale (0.3%, IIRC)
As for export., the problem there is no such thing as "cheap" nuclear power.
I don't have anything against nuclear. Build it. Build thorium. But the bottleneck in the Western world lies with the utilities that need to finance it who've been badly bitten by time and cost overruns.
Vogtle 3 & 4 were seven years late and $17 billion over budget (current estimates costing $35B).
The only way nuclear's numbers make sense are in highly regulated markets where utilities are willing to commit to to expensive, long-term electricity agreements.
