> China and Russia are building the most reactors.

Are there good estimates for the cost of nuclear power in China and Russia? The estimates we see for the US and Europe show it to be relatively expensive, but it seems likely that it might be much more cost competitive in an environment with less regulatory overhead.

This article (https://archive.ph/nhdr2) agrees with that: "China keeps the exact costs a state secret, but analysts including BloombergNEF and the World Nuclear Association estimate China can build plants for about $2,500 to $3,000 per kilowatt, about one-third of the cost of recent projects in the U.S. and France."

It attributes most of the cost difference to differences in interest rates, but I'd think that construction standards, regulation, and cost of labor would offer potential savings too. I guess these can help with other renewables as well, but nuclear seems likely to benefit the most.
