An alternative to emotional arguments is to look at the statistics.
Conversely, the emotional argument is the only one that brings nuclear power back. You must convince people that these projects can be done safely. You must convince people that, "This time will be different."
Look at what just happened in Germany. Or don't.
What happened in Germany was not rational, and it was not by any means good for the environment, or a net positive for German health and well-being.
The quantification of those risks is another matter.
The parallel fact, for example, that nuclear weapons require maintenance, and that maintenance requires budget, may make some shiver - not because of an "emotional" idea. It is because you look.
