No doubt about it, in terms of active reactors and output[1]. But if "the lead" means developing micro/safer/other kinds of nuclear power, I think that's a role that is currently up for grabs. While I personally think even investing in large-scale nuclear plants would be better than burning coal, that seems politically impossible, so it'd have to be something else (and a pretty compelling something else to outdo PV given how cheap that has become). 1: https://en.wikipedia.org/wiki/Nuclear_power_by_country https://en.wikipedia.org/wiki/Nuclear_power_by_country
