But despite the public distaste for nuclear, it has a critical advantage over other clean sources. It generates electricity that doesn’t fluctuate depending on the time or day or weather conditions, so it can help to balance out intermittent wind and solar generation, without requiring vast amounts of expensive storage or transmission upgrades to the grid. A next generation of plants that are cheaper, safer, and easier to build might also help assuage a skeptical public’s fears.
