Chernobyl Sarcophagus

[RichJohnson]

Additions and improvements being made to the original '86 sarcophagus.
More out of curiosity out of anything, what grade of steel would be used for components?
Is there a "nuclear safe" mixture of the concrete used for the shell, or does it drill on thickness?

I fail to see the science behind the fifth paragraph:

And apparently these guys (

are supplying the fasteners, is there no nuclear qualification needed?

RichJohnson:
It appears the science behind the 5th par is called "political science"- there is a new push to ensure the public now accepts routinely occuring major accidents as the new normal, so there is nothing to worry about anymore - their objective relates to "minimizing the economic and social repurcussions of an accident which has widespread contamination". Probably a good topic for a social psychiatrist's pHd thesis.

Aside from that , there may be advantages to using geopolymer cement in lieu of portland cement for the new sarcophagus- much more than 100 yrs life from geopolymner cement.
