"But nuclear is reliable and doesn't need this "natural gas assist". Even if a hurricane sweeps over an area, the nuclear power plants will keep working."
Actually, they don't.
"As a precaution measure, the reactor shall be shut down at least two hours before the hurricane’s strong winds arrive at the location. Generally this happens when the speed reaches between 70 and 75 mph (between 113 and 121 km/h)."

Also, they need electrical power to keep the reactor cool---typically the power grid and co-located diesel generators, not necessarily the best redundant backup system.
- mechanical_bear 5y agoIt’s only the older designs that need active cooling. https://www.technologyreview.com/2019/02/27/136920/the-new-safer-nuclear-reactors-that-might-help-stop-climate-change/ https://www.technologyreview.com/2019/02/27/136920/the-new-s...
- Aeolun 5y agoGiven how long it took Fukushima to cool down, does this actually do anything appreciable in the two hours before arrival?
- mcguire 5y agoI believe it means that, 2 hours before arrival, the reactor is off. Dead. Not generating heat. They'd need to start shutdown sometime before that.
