What does Chernobyl have to do with modern reactors. Not to mention that even Chernobyl was a result of a poorly thought out experiment as opposed to some inherent flaw in the reactor.
That’s objectively untrue. The RBMK reactor type as it was used in Chernobyl has a design flaw. It’s called the positive void effect:
This positive coefficient was another key aspect of the RBMK in reactor unit 4 of the Chernobyl power plant. In the events of the accident, the excess production of steam (meaning an increase of voids) caused the void coefficient to become unsafely large. When the power began to increase, even more steam was produced, which in turn led to an increase in power.[2] This led the reactor to produce over 100x its rated power output, causing extreme temperatures and pressures inside the core, and causing failure.
The positive void coefficient was directly responsible for the disaster: During low power operations the effect caused water vapour bubbles to be created in the reactor. Because of the lower density of the vapour the moderation of the reaction did no longer work and the reactor spiraled out of control. All the while there was no feedback to the control room about the increased reactivity, so the personal had no chance to assess the situation correctly. This lead to the uncontrolled chain reaction and the explosion of block 4.
After a while Nikolai Steinberg conducted an experiment in the other blocks of Chernobyl which showed that the positive void coefficient was causing the reactor to spiral out of control in low energy production scenarios.
That’s not right. The experiment was conducted after the explosion in an effort to prove Nikolai Steinberg’s suspicion that the positive void coefficient caused the disaster. The experiment was a success and Steinberg’s suspicions have been verified.
On 25 April, prior to a routine shutdown, the reactor crew at Chernobyl 4 began preparing for a test to determine how long turbines would spin and supply power to the main circulating pumps following a loss of main electrical power supply. This test had been carried out at Chernobyl the previous year, but the power from the turbine ran down too rapidly, so new voltage regulator designs were to be tested.
German goverment seems to be pretty hazardous to me. This coal shit, participation in Ukraine war, repression of people protesting against genocide in Gaza, supporting said genocide, vassalization to most dangerous belligerent government on Earth…
The data include accidents. You might feel differently about wind if a loved one died doing a wind turbine installation. The logic goes both ways.
I will reiterate: it’s literally safer than wind.
Look at the fucking numbers and not your feelings.
This is the list of the thirty worst accidents in civilian nuclear power plants. These have all been categorised as having caused substantial health damage. There is a definite risk in using nuclear energy
The above data include accidents. You are literally killing people by not going nuclear. Nuclear accidents are highly publicized but if (hypothetically) one person dies for every wind installation but they never make the news, it’s a death by a thousand cuts, and nuclear comes out ahead. That is hyperbolic but it’s emblematic of the situation, look at the fucking numbers. Nuclear is safer.
It’s not a choice either nuclear or coal power. We have to and we as a society decided to phase both of them out. Because of the concerns regarding nuclear energy production and the waste being produced, Germany opted for phasing out mucker power production in 2023 and aims to phase out coal power production in 2038 in order to get climate neutral by 2045 by using renewables energy in conjunction with green hydrogen power plants, of which forty are planned to be build in the foreseeable future.
Nuclear power production is not risk free, and there have been massive contamination of ground water in Germany in the old storage facility “Asse”. The situation in there is so horrific, that it has been decided to get all the nuclear waste out again and store it on the surface again.
I don’t think the effects of mistakes like these in handling nuclear waste are included in the before mentioned data. As are the possible horrific scenarios with high level nuclear waste stored on the surface.
“Massive contamination”, “horrific”, and yet the article points out most of the seepage is radiologically harmless. It is important to clear out the mine and it will be really expensive, I won’t deny that, but let’s not scaremonger and act like it’s Chernobyl 2. As well, let’s not pretend that new nuclear projects would suffer the same problems. A functioning country would see this mistake, regulate how waste can be stored, and that would be the end of it. As many other countries have done.
Let’s be clear: nuclear waste is a solved issue. We know how to store it safely, we know how to reprocess fuel to make it safe within hundreds instead of thousands of years. Whether or not we do that is an entirely political question.
And what then is the alternative? Wind doesn’t always blow, the sun doesn’t always shine. Battery storage would be prohibitively expensive and the amount of lithium required to be mined to supply an entire country’s electricity storage needs would be horrendous for the environment. Hydroelectric storage is ecologically devastating to a scale the public is largely unaware of and geography-dependent.
I am very skeptical about green hydrogen because it is far too politically easy to sweep the source of your hydrogen under the rug under bureaucratic obfuscation and the most economically viable method to produce hydrogen is to use fossil fuels and emit CO2 in the process, making it not really green.
“Every day, 13,000 liters of water flow into the Asse II nuclear waste storage facility in Lower Saxony, which is in danger of collapsing”
“There are quite a few quantities. If you just think about it: these 102 tons of uranium, 87 tons of thorium, then these 28 kilograms of plutonium. And then we have a mix of many different chemotoxic agents and pesticides. We have about 500 kilograms of arsenic. And plutonium is not only radioactive, it is deadly even at the size of a grain of dust. You shouldn’t even think about what would happen if this shaft were to flood, that would still be possible. And the mountain really pushes upwards due to its pressure. Into the groundwater. That’s a catastrophe.”
“These are waters that have direct contact with the radioactive waste, they run through a storage chamber and there we obviously have different pollution than with this water, which we collect up here…”
“We have pictures from the chamber where we see, among other things, a yellow metal barrel that was squeezed between a concrete barrel and a chamber wall, meaning it was completely destroyed by the rock mechanical pressure. And we have also seen damaged lost concrete shields.”
As stated before the idea is to employ renewable energy to produce green hydrogen for use in gas power plants. If you have no more coal power plants which is the target for 2038, you can not use it for hydrogen production. Germany wants to be self sufficient with regard to energy production, so we will have no other way to produce the hydrogen.
You are right in being sceptical, but IMHO the strategy is viable and can be implemented. And producing zero nuclear waste and be climate neutral at the same time is something we will have to achieve in the near future.

That’s an american vision. Let’s see what you’d say if half of your relatives were victims of the Chernobyl
Those are global death rates not death rates in the United States.

There’s a really good documentary about that, but alas it’s in German: https://www.zdf.de/dokumentation/zdfinfo-doku/tschernobyl-die-katastrophe-paradies-100.html
Nikolai Steinberg also coauthored a book about the accident: https://www.perlego.com/book/3418623/chernobyl-past-present-and-future-pdf
To sum up, there was an experiment conducted that caused the disaster, as opposed to it being a result of normal operation of the reactor.
That’s not right. The experiment was conducted after the explosion in an effort to prove Nikolai Steinberg’s suspicion that the positive void coefficient caused the disaster. The experiment was a success and Steinberg’s suspicions have been verified.
This is what caused the disaster

That’s right but Chernobyl wasn’t the only incident. There was one in Japan too…
Ah yes, I totally forgot about all those land tsunamis Germans have to worry about.
There are other hazards as unlikely as Tsunamis.
do tell
Wars
So far, the war in Ukraine is evidence to the contrary.
I’m sure you have the capacity to think of some on your own and don’t need my help with that.
Thanks for confirming that you’re just fear mongering here.

There is no long term storage site for high level nuclear waste in Germany. So the issue of nuclear waste is clearly not solved.
Intermediate storage facilities for high level nuclear waste are a security concern:
