i’m surprised the amount of “yeah, it’s broken” that’s in here.  the amount of “we have a lot of mop buckets going on, and plan to freeze the ground like a moat around a castle.”   which, explains the bits they left out.  it’s safe to assume that not only did all 4 suffer meltdown and inner breaches, but also that more than one reactor containment was also breached.  Corium in the Basement.  heres a clip of the robot they’re going to try sending in one of the cooling pipes so it can crawl around the bottom of the chamber and take some pics/temp readings.

also of note: free flu shots, injuries and deaths, they’re letting women in now, and while removing the gantry debris it fell back into the pond and all work was stopped for a bit.  lucky no boom eh?

comparing solar X-ray arrivals with the spikes in core emissions is left as an exercise to the reader.
