I can't complain about the first episode......Damn what those guys walked into and the Soviets trying to cover it up within the first hour of the disaster defies description.

Hmm, don't get HBO.
I wonder if they get into the "conspiracy theory" that the meltdown was caused to cover up the failure of this project? |

Wife is out of town right now but we are excited to watch it this week when she gets home

I only give it 6.5/10 because everyone speaks with a British accent. Its annoying as hell. They couldn't find any Russian/Ukraine actors?

Good first episode. Poor fuckin firefighters and families. Jesus.
Portraying Dyatlov as I expected. |

A RUssian accent would have been fine.

First episode was superb. Leaves you with the taste of nuclear holocaust in your mouth.

View Quote Listening to bad actors speak with heavy accents just for the sake of “authenticity” Half decent filmmakers have figured out that getting quality actors is far more important than getting an accent right, and it’s better to skip the accent than to force a shitty fake one. |

This video has some pretty haunting footage of the area about halfway throuh.

View Quote The elephants foot is significantly less radioactive than it used to be and is beginning to flake apart. The new containment arch is quite fascinating. Will be interesting to see if they can actually disassemble the existing structures. |

Superb irony. Mocking the lies of the Soviet Union, while at the same time … completely making stuff up out of their own technical laziness.
ETA: I'm going to walk back my criticism. Way back. If the episodes were all pulled together in one continuous piece, the totality of what this film team has done would simply trample over whatever technical confusion I would have had in mid stream. |

remember kids, it is entirely possible the whole thing was touched off by a small nuclear detonation that was a result of the runaway reaction

This figure was plugged into the calculations for Cherepovets, and it was then concluded that the part of the core that was released by the steam explosion contributed very little to the Cherepovets detections and therefore had little impact on the conclusions.

Quoted:
What was the graphite used for? View Quote In PWRs and BWRs (the most common reactors in the world), water is the neutron moderator. The fuel is enriched to such low levels, that without slowing the neutrons down into the "thermalized" energy region, fission isn't sustainable. And in PWR/BWRs water moderates these neutrons, and the convenient thing about water is that as it heats up, the density (and ability to moderate neutrons) goes down. Self correcting, if you will. Graphite's moderation, however, doesn't decrease with temperature like that of water, so a reactor like a Soviet RBMK doesn't have a natural tendency to decrease neutron flux as reactor power increases - and this makes RBMK operation tricky - and is at the crux of the whole Chernobyl disaster. |

Just for fun, and I've put this up before. Youtuber Carl Willis became acquainted with the widow of a scientist who worked on the Chicago pile.
Turns out her husband saved an, er, souvenir from the pile: A graphite brick COMPLETE with the two machined uranium metal slugs. Now, if these were just chunks of uranium it wouldn't be such of a much. Very long half life, therefore quite low (comparatively) quantity of disintegrations per hour. But these bits were actually in a functioning reactor, which meant that some of that material was transformed into nasty daughters. You can see him quantify and characterize that on this video. Now given when the Chicago pile operated, the some of that stuff has been through nearly three half lives but I wouldn't keep it in my living room. Still its a fascinating video!

I can't vouch for accuracy, but the first episode certainly had my attention.

Cerenkov glow is going to be present if there is sufficient steam/water density and gamma or beta radiation, and wouldn't necessarily be tied to any prompt response. That the paper would try so hard to correlate witness recollections, Cerenkov, and so forth, it's just a perplexing balance/imbalance of effort in their work.
When the reactor tubes breached, there would have been ample gamma and beta sources in that core to produce visible Cerenkov glow, given a sufficient presence of steam liberating from the core. |
