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.
Exactly and during that test the positive void coefficient caused the reactor to spiral out of control with no feedback to the control room, as detailed in the earlier post.
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…
“So far” is the most important part of that sentence and there are not only countries but also terroristic and radical groups which are much more dangerous for nuclear plants than regular wars
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.
That’s an american vision. Let’s see what you’d say if half of your relatives were victims of the Chernobyl

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

Here’s a paper about that: https://hal.science/hal-03117177/document
Even the nuclear power lobby organisation World Nuclear Association acknowledges that this is a massive design flaw: https://world-nuclear.org/information-library/nuclear-fuel-cycle/nuclear-power-reactors/appendices/rbmk-reactors.aspx
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
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…
indeed
Wars
So far, the war in Ukraine is evidence to the contrary.
“So far” is the most important part of that sentence and there are not only countries but also terroristic and radical groups which are much more dangerous for nuclear plants than regular wars

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.
Again no argument, just attacking me personally. I’d like to recommend this quick read to you:

Those are global death rates not death rates in the United States.
