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.
Here's a paper about that:

Even the nuclear power lobby organisation World Nuclear Association acknowledges that this is a massive design flaw:

The question is how you conduct the tests, and of course we have learned a lot since that time. Modern reactors incorporate these lessons making them much safer.
Fukushima is a reactor design from the 70s, and the risk with that design were identified at the time. Dale G. Bridenbaugh and two of his colleagues at General Electric resigned from their jobs after becoming increasingly convinced that the nuclear reactor design they were reviewing -- the Mark 1 -- was so flawed it could lead to a devastating accident. The problem with Fukushima was caused by capitalism.
And by extension I'm saying that it has no relevance when discussing modern reactors which do not have the problems Fukushima reactor had. Meaning that you're trying to use a disingenuous argument to make your point.
This is what caused the disaster

Right, it was a test that was conducted as opposed to normal operation of the reactor itself.
Tests will always have to be conducted to ensure normal operation. That's nothing out of the ordinary.

I agree that newer reactors are more safe than old reactors but there's still a significant risk involved. See Fukushima.

So your saying the reactor was not safe and should have never been built that way? I agree.
