Conclusion: "All these factors undermine the report’s central assumption that nuclear plants will be replaced by fossil fueled plants. To be fair, the UCS report does call for periodically assessing whether continued support is necessary and cost effective. But such support might already not be cost effective.

Either way, it may be best to get onward with the transition from fossil fuels and nuclear power to renewables."
