First U.S. nuclear reactor built from scratch in decades enters commercial operation in Georgia::ATLANTA — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.
I guess it depends on perspective. On one hand, it’s an enormous amount of land - on the other hand, the USA is extremely big. I personally think the footprint is significant. It’s not like we’d tear down suberbs to make solar farms, we’d tear down nature (undeveloped land).
The cost being the motivator that makes solar better than nuclear I don’t believe to be accurate. Short term, solar is cheaper, but also we’re making panels as fast as we can. It takes a lot of materials and is hard to scale quickly, so we can’t just decide we want to switch the USA to solar and think we’ll have enough panels in a decade even.
Additionally, nuclear isn’t expensive in the long run. It’s quite profitable and low maintenance. Nuclear waste is blown up by people who don’t understand it. And our grid is ready to be powered by nuclear. Our grid can’t yet handle the quick variablility of solar. If that weren’t a problem, we still need additional power from events where there isn’t a lot of sun for a while. Batteries may get us through the night someday (also another enormous manufacturing feat) but they won’t get us through the week.
If both can be profitable, it’s really a question of what we want to build. I argue that we can’t even run off solar yet without some new technologies being made. Nuclear is the quick fix we need. The only reason we don’t have it already is because of attitude towards it (“not in my backyard”), which I think would be different if people understood it.
The lifetime cost of of nuclear (build, running + clean-up) divided by the amount of electricity created is incredibly high. This report from csiro doesn’t include large scale nuclear but does include projected costs for small modular reactors +solar and wind. Generally large reactors come out behind smr especially in future projections.

Note the “wind and solar pv combined” “variable with integration costs” which is the cost accounting for storage, transmission etc. It’s not that high (at least up to the 90% of the grid modelled for 2030). The best end of the nuclear estimate is double the cost of that. The reasons that the storage costs etc. Are not as high as you may intuitively expect are explained in that report.
Maybe there is a place for nuclear in that last 10%, but not in less than that. Also as far as rolling it out quickly, look at how long this last nuclear plant took to build from planning to construction being complete.
I think that it is possible to manage the cleanup of nuclear and to make it safe, but it’s all just very expensive. To make everyone happy with the transition off fossil fuels it needs to be cost competitive and renewables are, nuclear isn’t.
Maybe Australia’s grid is 90% ready for solar, I’ve heard they’re pushing for full renewable in 2 States. But the USA’s isn’t ready.
Again, I understand that new installations of solar power plants are cheaper than nuclear. My points against solar are:
Meanwhile points agaisnt nuclear are
Both of which seem like much simpler problems to solve:
