The GOP is interested in nuclear power because they know that since the 60s the Left has been against nuclear power. They bring it up as a way to gore the Left's ox, not as something they're actively pursuing to fight climate change. The policy they pursue is trolling and antagonizing their domestic enemies. Any effect of this on climate policy is incidental.
