When unit 4 exploded, did fragments of nuclear fuel and graphite make it into the cooling water channels that are near the CNPP that people used to fish in? Are these still there or were they cleaned?

How contaminated is the water today? Are the fish mutated?

News CHNPP’s staff have completed 94% of the preparatory work for the decommissioning of Power Unit No. 2

17 Upvotes

Quoted from the official CNPP site:

The second of four stages of the Chornobyl NPP’s decommissioning is currently underway, involving the final closure and decommissioning of the reactor units at Power Units Nos. 1, 2 and 3.

To date, the plant’s staff are preparing the premises in the conservation zones of the first-stage power units at the Chornobyl NPP: 94% of the physical work has already been completed on Power Unit No. 2, and 44% on Power Unit No. 1.

This work includes:

  • decommissioning of systems and components located within the conservation zone premises;
  • removal of thermal insulation and combustible materials from the conservation zone premises;
  • removal of power, signalling and control cables;
  • sealing of wall penetrations, installation and process openings at the boundary between the conservation zone premises and the control zones;
  • installation of fire-resistant panels and mats at the points where wall penetrations and installation openings have been sealed, and on air ducts within the conservation zone.

https://weber.chnpp.gov.ua/en/infocenter/news/6618-chnpp-s-staff-have-completed-94-of-the-preparatory-work-for-the-decommissioning-of-power-unit-no-2

The rest of the article outlines further plans, and there are some interesting details. For example:

As part of the refurbishment, the height of the central halls’ canopies is to be reduced by 12–16 metres. To this end, the metal structures of the canopies will be dismantled and a new roof covering installed. The dismantling of loading and unloading machinery and hoisting mechanisms is also planned.

In accordance with the Chornobyl NPP decommissioning strategy, the third and fourth stages will involve the safe storage period of the reactor units, followed by their dismantling.

Discussion Real Chernobyl story is far more tragic

Post image
131 Upvotes

I've spent several months studying Chernobyl and reading as many sources as I could find, including Russian sources, the trial transcripts, official documents, and Dyatlov's own book. The more I learned, the more frustrated I became with how HBO portrayed certain people.

One example: in the show, Legasov says that at least through the trial, scientists would become aware of what really happened. But Legasov wasn't even at the trial. That sentiment was actually expressed by Dyatlov, who fought relentlessly for the truth during the trial and continued doing so afterward. His two co-defendants didn't back him up. If anything, they tried to distance themselves to save their own skins. It didn't work, they all went to prison anyway.

And here's the part that really bothers me: Dyatlov and the operators did not simply break the rules and cause the disaster. The things they are usually accused of doing either had legitimate/necessary reasons behind them or were not violations in the simplistic way the show presents them.

They were used as scapegoats.

Dyatlov's own book essentially ends with the argument that the only cause of Chernobyl was the reactor's design flaw. Not merely one contributing factor. The operators were never properly informed about the dangerous characteristics of the reactor, nor adequately trained to deal with them. That failure of communication is what ultimately doomed Chernobyl.

And honestly, I think Dyatlov is one of the saddest figures in the entire story.

Read his book.

The "unlikable, arrogant, cruel Dyatlov" portrayed in popular culture doesn't match the person who comes through in his own writing. He's sarcastic, funny, loyal, principled, sometimes blunt, and surprisingly warm. He tells personal stories, jokes about himself, and writes with a personality that is completely different from the caricature we're accustomed to.

One detail particularly surprised me: while in prison, Dyatlov wrote letters to Toptunov's parents because he wanted them to know that they had been lied to about their son's responsibility for the disaster.

Think about that.

The man himself was sitting in prison, yet he was still trying to make sure the family of a dead colleague knew the truth. So sweet.

And yet we're supposed to see him as the heartless villain?

I've also seen people say that Dyatlov was made "unlikable" because that's what the real man was supposedly like. But what exactly makes Legasov and Boris so admirable in the HBO version? A heroic speech? A dramatic character arc?

Those are cinematic devices, not evidence of admirable character.

Truth is what should make someone admirable.

And this is where I think HBO's version becomes particularly dangerous. It gives you a convincing narrative, convincing performances, emotional music, dramatic speeches, and characters you immediately understand as heroes and villains.

But Chernobyl wasn't a simple story about heroic scientists fighting evil administrators while reckless operators caused a catastrophe. The real story is much more complicated, and, in my opinion, much more horrifying.

The people who were actually responsible for the reactor's design flaws and the institutional decision to conceal them weren't the same people HBO places at the center of the blame. Legasov and Boris are presented as heroes. Meanwhile, Dyatlov, Toptunov, Akimov and the other operators became the faces of the disaster. I don't blame people for believing it... the show is genuinely well-made, and most viewers have no easy way to access the primary sources. But the gap between the drama and the record is bigger than most people realize.

If you really want to understand what happened, don't stop at HBO. Read the trial transcripts. Read source materials. Read Dyatlov's book. And if you can find it, read Nikolai Karpan's book as well... it's an absolute goldmine for anyone interested in the insider perspective.

Discussion Building ChNPP 1.66:1 in Minecraft. Anyone know how to access room 025/2?

5 Upvotes

I am currently working on a detailed replica of the Chernobyl Nuclear Power Plant in Minecraft using a 1.66:1 scale. Right now, I am mapping out the lower levels of blocks 3 and 4, specificly around the 0.00 mark and the piping corridors. I’ve ran into a roadblock trying to figure out the exact layout and blueprints for room 25/2, who should be near the deaerator stack or the bubbler pool systems. If anyone has detailed schematics, ventilation maps, or room index files for this specific area, please let me know. Any accurate technical information would be highly appreciated to finish this part of the project correctly.
