> Environmentalists have been some of the more effective lobby groups for locking in fossil fuel use through 1980-2020 when we really should have been transitioning to nuclear power.

If environmentalists are so effective, climate change would have been a higher priority over those decades. It seems likelier to me that there's other, more convincing reasons we haven't rolled out nuclear at a huge scale. For example the following are typically more convincing and applicable to nuclear as well: high costs, high political risk, fossil fuel lobbying.
