Nuclear power is still better than burning fossil fuels regardless, and probably has a role to play as a scaleable demand-responsive source.
However for the past decade or so, every time a new nuclear project starts the cost of wind and solar drops substantially before it’s complete. This absolutely ruins the nuclear project’s original cost/benefit analysis and makes continued spending on it look irresponsible. Wind and solar are outcompeting everything else, which is probably a good thing overall. If energy storage tech becomes more affordable/effective we might not need nuclear at all.
Salon has no respect from me, so I’m not going to generate a click for them.
Since I’m not too familiar with nuclear - how would the on-demand scalability work? My impression has always been that reactors are generating energy at a fairly constant rate.
Oh no, the whole point of control rods is to adjust the rate of reaction in the core, which adjusts the rate of neutron output which adjusts the rate of steam production. Newer reactor designs are even more flexible in how the rods can be used.
Not really. Reaction change when moving the rods is almost instantaneous. Random spikes in grid usage are not that random and any competent power providers can predict and plan accordingly. The only real concern is decay heat things like xenon build up down the road, again something the industry can predict and plan around as standard practice and western built reactors have safety systems built around preventing those factors from becoming serious issues.

Nuclear is best used a base load, it scales in the sense that you can build more plants, but the plant output can’t be adjusted as rapidly as the tiny natural gas turbine plants, reservoir-storage, battery array, or other sources.
The best use for nuclear output in a surplus phase would be storing the energy (water reservoir pumping, battery arrays, etc.) or expensive wasteful processes (electric steel plant ovens, hydrolysis to generate hydrogen fuel.)

Huh, the more you know. I always though the rods were only adjusting it at a single percentage point rate, just enough to not let it blow up!
Thanks for the answer!
And yet it still takes several minutes to hours to make significant changes without causing problems…
Also its expensive and not renewable and water is an issue as well.
