well yes but also not really.

Nuclear reactors are incredibly expensive, take forever to build, test, and ensure they are safe, often require additional not-so-green/renewable secondary materials/processes that are conveniently ignored (mines, for example) and waste disposal is a semi-serious non-solved issue.

All of these factors combined are significantly more important than the land the power is generated on, as 99% of the world has space somewhere.

The reality of nuclear power is that it doesn't make sense in 95% of scenarios anymore because battery + solar / wind is effectively free in comparison, can be built and scaled extremely fast, and is many times more renewable because basically everything is recyclable.
