Which is definitely helpful for utility that’s constrained by space. For instance, with the nuclear powered freight shipping that Jiangnan Shipyard is looking to pioneer.
But for urban grid power or industrial production at the continental scale, space isn’t an issue. One reason why states like Texas and California are running away with renewable power even in the face of hostile political headwinds. Real estate is far cheaper than the energy is produces.
For the places that have enough land and environmental conditions suitable for wind/solar, that is true. In remote communities, just getting the materials for a wind farm there is incredibly difficult if there’s no warm water port for a ship to deliver the blades for instance. A nuclear reactor in a shipping container can be driven by transport on the logging roads or even air-lifted in. It’s not a universal solution, it’s something specific to fit a community’s unique needs.

Again, who doesn’t have this access?

Remote communities don’t have the kind of energy demand that nuclear power fulfills. Nevermind how it’s always going to be more expensive to build a nuclear generator than a big fan connected to a dynamo.
It’s not a universal solution
It doesn’t need to be, when the bulk of what we’re trying to replace is coal and natural gas.
I agree with this; I think the “universal” argument and subsequent infighting is propped up by the oil lobby to slow us down. I just think it’s important to highlight how efficient nuclear is. We should be using both good tools to solve this and part of that is knowing how good both are so they’re not unnecessarily ignored.
That argument holds for existing proven tech like large nuclear and solar, but convincing governments to invest in unproven and unlikly tech is a great way to prevent actual transition to occur at all. They sop up cash and give governments reasons to build nothing now, or eventually build expensive tiny demonstration systems that do not effect the overall fossil fuel market. That list would include things like small modular reactors, hydrogen power, fusion, etc.
i am very divided over SMRs, but large traditional reactors have been proven many times over, and in any case investing in unproven tech (by any government but the US) is what led solar to be this good now in the first place
not sure what that means. large traditional reactors are a lot more efficient, especially at scale, though more costly due to historical and current lack of subsidies.
There are communities in northern Ontario that are only accessibly by airplane ~6 months of the year, and those 6 months also have very low amounts of sunlight. They’re not quite north enough to be completely dark all day, but they only get a few hours of useable light per day in the winter.
This means that a) solar is less effective in the winter, and b) if there is damage to a wind turbine blade in the winter, they may not be able to get a replacement until spring.
Remote communities don’t have the kind of energy demand that nuclear power fulfills
Each reactor cell produces about 1MW, which is about enough to power a small town of about 1,000 people. They can also be air-lifted meaning if it needs to be replaced during the winter, that is still possible.
SMRs will be neat if they actually work, but there is no demostration that they can be remotely economically feasible. Even considering carbon emissions, it would be cheaper and more effective to improve the carbon footprint of the main power grid by a tiny fraction of a percent and then just give those small northern communities modern fossil fuel plants, maybe supplemented with renewables over time.
For large northern communities, grid connections are going to be the eventual solution either way.

Yes. But in proving them, we learned that efficiency of scale is required.

And if there’s damage to a nuclear facility?
They hook it up to a helicopter and take it away. It’s literally in a shipping container.
