> Nuclear reactors could provide power almost indefinitely If properly operated and maintained. Maintenance requires lots of knowledge. The reactor itself is simple, but the stuff to turn heat into electricity typically isn’t, involving the use of steam under high pressure, liquid sodium, or other dangerous and/or corrosive stuff. The supply chain for parts and tools to maintain that goes deep. It would not surprise me if it would require millions of people to keep one running safely for decades.
