First, point out that Chernobyl, 3 Mile Island, and Fukushima amount to extremely small numbers of deaths relative to the power these plants generated. For three mile island and Fukushima this figure is zero among the public. Less than two dozen among the plant workers (all of which died due to the hydrogen explosion not radiation). The areas that were evacuated are now safe to return. Chernobyl was worse, but th Soviets didn't even bother with secondary containment. They didn't bother to put a concrete dome over the reactor. Even then, ~200 people died. This is a fairly small death toll for a worst-case failure. Contrast this with hydroelectricity, for example, which has resulted in the deaths of tena of thousands of people and the displacement of millions due to dam collapses [1].
Competition in the form of wind and solar are intermittent, requiring storage on a massive scale to offer a path to decarbonization. With 12 hours of energy storage, the US could reach 80% renewable generation. To get to 100% we need 3 weeks of storage according to estimates [2]. Currently, we have 8 seconds of battery storage compared to our 11.5 TWh daily electricity consumption. We have 4 minutes of hydroelectric storage, but hydroelectric storage is geographically limited. Increasing this by a factor of 180 is not feasible.
In short, if the goal is decarbonization wind and solar don't actually present real competition.
