Well when I operated reactors for the Navy, we procedurally couldn't exceed a certain outlet temp, but I was not only mechanically possible, but occasionally required when we were operating in very warm waters ;)
Nuclear in America is expensive because we stopped building reactors for 40+ years, so all of the supply chain and expertise atrophied.
France is doing just fine power wise and doesn't rely on Russian gas to do so. One could argue their actions in North Africa to secure their uranium reserve, are equivalently bad, but that goes for the minerals required for batteries/solar panels/wind turbines, all of which require a massive amount of material to be pulled out of the ground and be processed with chemicals.
It's unlikely for the lake cooled reactors like 9 mile point to suffer from high inlet temps because the bottom of the lake is a massive heatsink which is already used by some municipalities for cheap district cooling.
I think solar and wind are good for land that is developed but underutilized, like a rooftop, but bulldozing swaths of desert, which hosts its own unique ecosystem, just to coat it in silica and metal feels counterproductive.
Nuclear power is just so energy dense that it makes little sense not to use it. It could completely eliminate oil in heavy polluting industries like shipping. As well as still being able to tie into our current power grid, something that still isn't addressed in "green circles".
