The site of the Chornobyl Nuclear Power Plant (ChNPP) remains a unique location, as what’s left of the No. 4 reactor is the only place in the world where you can find significant amounts of what is called corium. An amalgamation of nuclear fuel, fuel rod cladding and whatever materials like concrete that the molten mass came into contact with, Soviet scientists initially struggled to make sense of this material, leading them to even have it shot at to get samples.
In this video documentary by [That Chernobyl Guy] these struggles by scientists both in and outside the USSR to comprehend this wholly new material are detailed. Much like trinitite – created by a US nuclear weapons test – these are amalgamations of material combined under extreme conditions. In the case of the ChNPP accident, the botched turbine spin-up test and disabling of all safeties by the operators allowed the bottom core chain reaction to run unconstrained, producing the massive steam explosion that flipped the biosafety lid of the RBMK reactor, while also fully melting the core material that then melted through the concrete below the reactor.
Although this Elephant’s Foot is only a tiny fraction of the total mass of corium inside the No. 4 reactor, it got rather infamous for supposedly being highly radioactive and lethal. In reality it’s one of the least dangerous parts of the exposed corium, and repeated sampling attempts along with internal degradation due to radioactive decay and weathering before the NSC shelter was installed have led to it mostly turning into slightly radioactive, rusty-looking dust at this point.
Also covered in the video is how the corium in the destroyed reactor is likely to be retrieved for final disposal, with robots cutting into the sides of the reactor building rather than trying to navigate destroyed corridors and staircases. This way it might be possible to remove most of the material without the issues that stymied Soviet engineers in the 1980s during their sampling attempts.
