Theyve had to start shutting down nuclear reactors in summer when water levels get too low,
This is a fake news. Period.
Some reactors had to REDUCE THEIR OUTPUT because otherwise they would exceed the temperature increase they’re allowed to cause in the river, this to preserve life in the river. No reactor was shutdown because of a low water stream.
What happened last year is a systematic defect was found in an external protection layer, and the decision was made to fix all the reactors having the same potential defect at once. The work took longer than expected, and that caused France having very limited capacity for months, causing worries about power outage.
Not to say it could never happen in the future, but it didn’t yet.
No, I don’t mean to destroy life in the river. I mean to highlight the difference of impact between going from 90% of your capacity to 0% in one information to reducing from 90% to 80% or even 70%.
Shutting down a nuclear reactor is quite a big deal in terms of operations. Restarting it is not like turning back on a switch either. Claiming a reactor was shut down makes it sound like a much bigger deal than what it was.
Actually we can make nuclear molten salt reactors (working small scale stuff exist for long decades).
Since the medium is liquid, it has much better utilization of the fuel, there is no pressurized radioactive water reservoirs (which is the actual issue with current reactors), to stop the reaction, you drain the fuel circulation into a container and you are done, no need to supply water to prevent criticality.
But since those molten salt reactors could not be used to create plutonium for weapons, the current reactor design was chosen during cold war era.
They have some drawbacks, like slow startup times, but the cons it provide are incredible.
MSRs and LFRs are horribly unreliable and don’t last. There hasn’t even been a successful demo reactor and the technical issues for running one safely at full power long term don’t even have proposed half-solutions.
cheaper and vastly safer alternative techs are available?
That’s the problem “cheaper and vastly safer” alternatives AREN’T always available. People continue to talk up Solar, and Wind, but they’re not viable for a majority of users of coal and natural gas plants. To produce the power that Nuclear does in square mile of land, you need 50 square miles of solar at least, and over 360 square miles for Wind. And that’s also saying you need viable places, because Wind turbines can’t just be thrown up anywhere, nor can solar.
Coal and Natural gas is more efficient by a factor of at least 10 in land space.
If you’re in the middle of nowhere, that’s viable, if you live in a big city, that’s going to become a problem quickly.
Inkai uranium mine produces about 40W/m^2 in fuel for the actively leeched land where everything is killed by the sulfuric acid and vehicle movement.
If you include the 15km buffer where you can’t live or eat anything it’s about 20W/m^2
Solar averages 20-50W/m^2 with current tech.
Rooftop solar uses no land. Agrivoltaics can have negative land use (adding the solar reduces the amount of land needed for the crops under it). Roughly 30m^2 of roof + 30m^s of facade or wall is sufficient for the average high income country european’s final energy use.
Solar uses a strict subset of the materials needed for a nuclear plant, so land use from the uranium mining is in addition to construction.
Like every pro-nuke lie, your land use pearl clutching is the oppksite of the truth.
The statement that “cheaper and vastly safer alternative techs are NOT always available” is not accurate. Solar and wind energy are becoming more viable as technology improves, and the land requirements for these technologies are not as significant as they once were. In addition, coal and natural gas are not as safe as they are often made out to be. Coal mining is a dangerous occupation, and coal-fired power plants can release harmful pollutants into the air. Natural gas is also a fossil fuel, and its combustion releases greenhouse gases into the atmosphere.
The cost of coal and natural gas is likely to increase in the future, as the world’s reserves of these resources dwindle. The environmental impacts of coal and natural gas are also becoming increasingly well-known, and public pressure is growing for a transition to cleaner energy sources. The development of new technologies, such as battery storage and smart grids, is making it easier to integrate renewable energy sources into the electricity grid.
In conclusion, there are a number of reasons to believe that cheaper and vastly safer alternative technologies to coal and natural gas are becoming more available. These technologies offer a number of advantages over traditional fossil fuels, and they are likely to play an increasingly important role in the global energy mix in the years to come.

There are a few testing facilities like chinas https://en.wikipedia.org/wiki/China_Experimental_Fast_Reactor and it was already tested and producing power. And they are planning to start a functional plant connected to the grid https://en.wikipedia.org/wiki/CFR-600
So it seems much more than a half-solution…
You’ve now swapped from molten salt reactors to sodium cooled ones while pretending they’re the same thing.
CFR has also never run without using U235 as its main fuel source.
Mind-boggling stupidity as always.
Sodium is in a molten salt form in those reactors…
