In electricity generation, it typically can’t be throttled reasonably in a way that allows quick reaction to changing demand. Most reactors’ power output is regulated by changing the chemistry of the coolant, which can only be done gradually, Using quicker control rods for everyday power adjustment rather than only for shutdown and startup, is avoided to avoid uneven, and therefore inefficient fuel burn. While it could be done, it would make nuclear power even more uneconomical than it already is by forcing more frequent shutdowns for fuel changes.






It was never economical. Nuclear power was heavily subsidised for other reasons than electricity generation. Any country that runs a sizable nuclear industry for power generation does have the capability to develop a nuclear weapons programme in relatively short order. (Usually a matter of months)
It’s basically nuclear deterrent light.
