The spent fuel facility I worked at had cages that maintained fuel rod spacing. Almost as important, it had a fairly common Stortz hose connection on the outside of the building that could easily by connected to a firetruck or hydrantfrom a safe distance and behind shielding. I can’t believe a spent fuel water pit would not be equipped this way anywhere in the world! Something ain’t adding up again.
Good info on current status seems so hard to get
Based on the explosions and pictures of the wrecked buildings, I’d guess a lot of equipment and plumbing was destroyed.
