I'm going to assume one already knows about the Chernobyl Reactor #4 meltdown accident on Apr 26, 1986.
I've seen a lot of information about the building and installation of a "sarcophagus" to contain the radiation. But evidently I didn't note any of that information because I can't find it.
The sarcophagus was installed in 2016, and it now shows up in satellite images. It was built on the bare land on the left of this image where the radiation levels were lower, and then it was rolled into place when completed.

I fired up Google Earth to get an image of its construction position.

This is the post that motivated these notes.

TechTimes posted More than 30 years after the world’s worst nuclear disaster, Chernobyl is finally seeing real hope. Scientists have slashed airborne radiation in the exclusion zone by nearly 50%—without digging, chemicals, or waiting centuries. The breakthrough comes from Swiss-based Exlterra, whose NSPS tech uses high-speed positrons to neutralize harmful isotopes like cesium and strontium, all while leaving the soil untouched. What once took 24,000 years to decay could now take just five. ☢️ A turning point for Chernobyl—and maybe the whole planet. 👉 Here’s how they did it — https://engineerine.com/chernobyl-47-less-radioactive/ |

| engineerine [The article keeps repeating "no excavation and no chemicals" but it doesn't say boo about how the positrons are generated. I thought generating antimatter particles was hard. Could positron bombardment also be used to clean up nuclear waste so that we don't have to deal with the NIMBY (Not In My Backyard) problem?] |
