I'm honoured you quoted those words but I thank you for your amazing work, especially condensing, bringing attention to Fukushima, in its various
twists and turns, in a way that anyone can understand and to a wider audience.
Had a second look at the videos, proper downloaded them.
Regarding the statement I made to you AC, my apologies for the language but it was surprising to say the least!
Here is another angle similar to what AC posted, pretty sure this is a tepco shot from earlier inspections of SFP3 April 12 2012, labelled 'cask
yard'. Wouldn't be much reason to inspect these twice if they were empty, right?
Yet to see a fuel assembly sitting between those gaps. The metal exterior parts are clearly fuel rod guide channels. So the rod assembly has to be
very narrow as to be shaded to not be shown. Problem is the camera in the latest inspection definitely has a light on it (evidenced by colour
temperature shift), it doesn't seem to do much to the shaded areas at all, especially not showing anything near as wide as the handle and top plug.
That said, light reflecting off the top surface won't help exposure levels for camera, so it will struggle to pick up shaded areas behind it. Kind
of like taking a photo of someone standing in a daytime backlit window, without flash. Still I would expect to see something indicated there in at
least one gap with the handle above it. A metal side of a fuel bundle should reflect light too.
Not that it is proof but adds to evidence to consider; the shadow part of the fuel rack (where fuel should be) and the rear of the photo (where it
gets too dark and low of a visibility to distinguish objects) have practically the same colour and brightness level. Fuel emits cherenkov radiation
for quite some time as well, so should be visible if loaded on the edge too in recent times. Like this but less apparent:
Other than light that appeared to be beaming upwards from the SFP, around the time they were transparency testing with a top down light, I have not
seen illumination sources from within the fuel rack at any point at Fukushima.
I hope like hell ACs catch and my impressions of it are wrong. R3 did have less fuel loaded into the pool, still quite a decent amount, but why does
it look like nothing is below the handles at all? Handles which signify a populated fuel channel.
Not to mention this;
Closer here in B/W to attempt to boost shading resolution
Part of an internal fuel channel guide appears to be on a 25-30 degree angle, this is an indication that fuel may have shifted, melted or physically
been damaged in the pool. Visualise that metal part being over 4m long, then wonder how many fuel channels may be disturbed in that one row alone.
But what on earth deformed it that way from the underside? Perhaps this is evidence Arnie Gunderson may like to consider in regards to his prompt SFP
criticality, which to me is still entirely plausible, in conjunction with an R3 prompt corium criticality, providing the neutrons to trigger such an
