Of course a 1960's design isn't adapted to current weather conditions. That doesn't mean the whole technology is useless, like so many commenters imply.

Any new build can and will include cooling adapted to hotter conditions.

There's a nuclear reaction in the sky beaming free energy to us, let's just use that
According to solar statistics by country in 2025:

https://en.wikipedia.org/wiki/Solar_power_by_country

Hungary had the highest share of produced solar electricity of all the countries in the world 27.3%. And even with this results nuclear energy is usefull for them and plan to build new reactors. (with help from Russia, so there may be same changes in this plan)

Hungary is already using that (today we were 90% carbon-free thanks to solar), the problem is what to do when it gets dark.
Batteries?

Starting this year, in Romania you cannot put new PV capacity online without the storage for it, is mandatory. Possibly for existing ones, but I am not sure.

Yes, absolutely colossal amounts of batteries though - what if it’s quite hot but also cloudy for 5 days in a row?

You either have to significantly oversize the PV (easier said than done, when its energy density is already not that high per m2), or have enough batteries to last for multiple days of full load. If you do the maths that’s a lot of batteries

>what if it’s quite hot but also cloudy for 5 days in a row?

The main idea is to then import power from somewhere sunny and/or windy or mountainous, using money you saved when they had the rain and you had the sun.

Batteries and other storage mechanisms will gradually reduce the need for doing so, but aiming to entirely eliminate all need for cooperation with others seems a bit paranoid.

They're being installed but it's going to take a while.
Much faster than any nuclear build though.
Sure, but it doesn't solve today's problem with the low Danube.
Mechanical ones so we aren’t left with a waste disaster in 10-20 years?
In Poland you cannot own big capacity storage because it makes you independent from the grid and Gov does not want that.

So you can have storage, but not too much, only as much to still be dependant on the grid.

See the hypocrisy here?

You are not allowed to have own PV and big capacity storage without connection to electric grid?
"the problem is what to do when it gets dark"

Batteries (or pumped storage hydro, which is more like a gravity-driven capacitor)

Hungary is flat as hell, there's nowhere to build enough hydro storage.

But yeah batteries would be nice.

AFAIK the mountains are about as high as Wales? It looks like there's a 600MW storage scheme in the planning stages. That's about a third of the capacity of Wales's largest system (which is the biggest in Europe) and about twice the capacity of the second system.

It's a meaningful contribution I would have thought.

You can do low(er) head pumped hydro storage [0]

Can't speak for Hungary specifically, but the problem with flat terrain wrt hydro storage isn't just elevation difference - which can be offset with flowrate - it's the large surface area to storage and to depth ratios.

Large lake means more losses, mainly due to evaporation, but seepage is also to be expected. Now put this fact in the thread's context: water shortage/stress...

Collect solar power in orbit (where sunlight is uninterrupted) and microwave[0] it to earth.

I'm fairly sure that when it's dark where I am (because I'm in the shadow cast by Earth), it's also dark in orbit above me (because it's in the shadow cast by Earth).
Calling the sun’s fusion "a nuclear reaction" in a discussion about fission reactors is a bit silly.

> let's just use that

Also, let’s use both?

It's not matter of "can", it's a matter of "how much does it cost?" and "who pays for that?".
Precisely why the Netherlands does not have nuclear power plants. Cheap coal. Cheap oil. Cheap gas. And now cheap wind and solar.

They just absolutely cannot math the math which leaves ideology and this ain't France.

That math leaves out externalities when pricing gas, oil and coal. You may have heard of a few fires going on in Europe in addition to nuclear plants shutting down?

Beyond that, those resources are also the lifeline for a dictatorship in the east causing increase defense spending.

There definitely is no such thing as cheap gas, oil or coal for Europeans, all things considered

The one that shut down in Romania is a CANDU, built in the 80s.
More like a CANNOTDU ;)
