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.
The appeal of solar and wind for me is how they can enable a decentralized grid. Anyone could set up these utilities according to their needs, which builds societal independence. Also means less resources are likely to be needed overall.
If by decentralized you’re mainly referring to rooftop solar, it’s unfortunately the least cost-effective way to generate electricity. The $/MWh for rooftop solar is even higher than nuclear on average. Wind and solar are more cost-effective in grid-scale installations. A decentralized/individualized grid would actually require more resources.
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.

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.)

Right but if you’re off grid, it’s kind of irrelevant what in-grid costs, it’s just nice that it’s an option at all and that it keeps getting cheaper.
Yeah, grid-scale is exactly what I had in mind. I admit, I’m not knowledgeable in utility engineering. Looks like some research is in order. :)

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!
