Wind turbine gearboxes use steel, aluminium or brass.Both those points are simply generalisations, the parts corroding are special lightweight alloys chosen specifically for resistance, chosen for there ability to be additive manufactured and none are plated. Titanium is only one of them, there is very little steel it's too heavy. And you would know mixing metals in such and environment can make things even worse without mitigation steps.
The wind turbines are in the same locations, but none survive 30 years on original parts, just like ships have been in dry dock and recoated dozens of times and had many components replaced.
I was sponsored by the Fed's to go to Germany and study this very issue among others a decade or so back.

The real reason why nuclear power is becoming irrelevant as a power source is ecomics; it's cheaper to use sustainable energy sources and the risk factors are much lower. It's actually a bit scary that private enterprise is driving the change to sustainable energy sources and dragging governments along in their wake.
The world changes a lot in that time.
Nuclear power has a long run up to build one.
In that time the power mix changes to do more with what comes online than anything going offline.
I think nuclear will make more sense both financially and bang for buck. There are a multitude of reasons not to build them and its got to do with the no one wants one near them factor more than anything else IMHO.
Thats fair. I don't have any good answers but gum trees around my property limit the viability of solar panels at my place.
Id be on the roof cleaning a lot.

@Thry
Cut down the gum trees and use them for firewood. ?

Some are even trying to claim that the SKA emits harmful radio waves, focussing the energy of the universe like an Egyptian pyramid no doubt. Remember pyramid Power. So their protest solution is to make even more RF noise in an attempt to damage / degrade the performance of the SKA! :

The fact of the matter is that nuclear power plants are being decommissioned and not replaced. I think that's more to do with economics than environmental/climate change issues; renewables are cheaper and the baseload concerns are really just hot air. Of course, storing renewable energy is not just about batteries; molten salt, heated sand and the generation of renewable fuels like hydrogen are realistic alternatives.
My house is surrounded by gum trees and I'm about to double the number of solar panels on the roof. The only problem I have is lichen growing on the panels.

55 new nuke plants being built and plenty more being uprated with 165 uprates in the USA alone.
Nuke plants get retired due to operational lifespan being met and its estimated that 123 will be retired by 2040 but 308 will come online.

With breathtaking cynicism and through a callous military lens, let me put on my devil's advocate hat for a moment with an obtuse view on nuclear energy.
Were I an enemy, a geographically distant enemy (or perhaps a terrorist), of a nation with nuclear power plants, I'd only need to destroy/sabotage them to get real 'bang for my buck'. Not only would I cause power supply issues but I'd have released some pretty harmful (to say the least) particles into their air/environment. And then when they were deploying enormous resources to limit the damage... they'd be weakened and primed for another strike.
Every power source has its pros and cons. None is a panacea. Just like our elections, so much is about choosing the lesser of the available evils (in a non-biblical sense).
Okay, the cynical cap is now off... phew... that was depressing! Right, onto more important issues... I wonder how our new look defense will stand up to the Dawks today?

The reality is fossil fuels out and nuclear in at some stage and like I said before people's idea that it's one nuke plant hidden in the outback somewhere isn't how it works and one means more if you want a decent chunk of your power from nuclear sources.

If you caught that idiot Pelosi two days back saying the Democrats were on a mission to save the planet, it just demonstrates that the November mid terms cannot arrive soon enough.
