So, I apparently can't add links into my messages unless I post more...ugh.

Anyway, the old object shelter/sarcophagus is made mostly out of concrete. Concrete acts as a pretty decent barrier, and I'm assuming is far cheaper and easier to come by than lead...especially the amount of lead they'd need to construct the object shelter.

Regarding the original sarcophagus, the bulk of it was made out of concrete. According to the Wiki article on the NSC the frame is made out of steel, the external cladding will have three layers (it appears to be steel also, but I'm not certain), and the inside will be covered in polycarbonate.

Keep in mind, the concern is to contain the damaged reactor core and any radioactive particles that could escape if the existing object shelter/sarcophagus collapses (spoiler alert: all those particles get kicked up into the air, spreading contaminants far & wide). The new NSC is far more stable, and will also allow crews to start dismantling the old object shelter and begin removal/decontamination of irradiated components.

Hi, what do you mean with "decontamination of irradiated components"? How can you decontaminate something radioactive? I'm just curious.

Oy...yeah, I think I meant a different word other than 'decontamination'.

Proper containment and/or disposal of the irradiated components inside the object shelter would have been a better choice of words.

Update from ChNPP.

And from the webcams, you can see that they lifted another "door" on the east side.

Update from ChNPP. I forgot to mention it earlier, but they got an extra 530M€ for the project, with 85M€ still needed.

A picture from Alexander Sirota.



And a snapshot from the webcam. You can see the progress on the south side cladding. The south-east crane (rightmost on the picture) doesn't have much more work to do.

Update from ChNPP. Nice close up of the bridge crane sections.

If you want more information about the bridge cranes, here's the official page with a video.

Both sections will be merged before the whole NSC is moved. The slidding probably won't happen before the second half of 2016 (guesstimate).

That bridge crane has a very interesting concept/mechanism. Thanks for sharing!

Well...it has taken almost 30 years to get this far already.
