> 4,700 cubic metres per second in July, whereas on Wednesday it was down to less than a third of that, at 1,600cm per second. Did a double take at measuring water flow in cm per second. At least it isn’t in busses or Eiffel or something.

People arguing for one alternative over the other are usually politically motivated. I feel like you are doing the same. Sometimes nuclear is a good fit, sometimes renewables is a good fit, sometimes fossil fuels are a good fit. Most of the time a mix is the best fit. It depends on what you are optimizing for and what is geographically, (geo)politically and economically possible. All these systems are then built usin…
>sometimes fossil fuels are a good fit. Oh come on.
Where have all the "what do you do when the wind doesn't blow and the sun doesn't shine" commenters gone?
And a closed water loop. China builds them on a desert and we cannot build them anywere in Europe due to plain stupidity.
I wonder if any new hunger stones have been found since the Danube's wafer level reached this new record low. https://en.wikipedia.org/wiki/Hunger_stone

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.
So you can have storage, but not too much, only as much to still be dependant on the grid.
See the hypocrisy here?
So nuclear isn't the solution after all.
Its only where shortcuts have been taken with cooling that there will be issues.
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.
The one that shut down in Romania is a CANDU, built in the 80s.
I find it interesting the discussion here is entirely about water temperature whereas the shutdown is entirely about NPSH. True there is a small different in NPSH pump limit of hot summer water vs cold winter water, but not as much as you'd think. Its not that the intake pipes are hanging out in the breeze above water; most pumps are designed not to cavitate at a certain input pressure (often pretty low) and I was bo…
