Two facilities in the city now hold over 5,500 metric tons of ash, and that figure continues to rise. The city is under pressure to find storage space and explain to residents how the ash will be buried, but no immediate solution to the problem is in sight.
At the beginning of this month, I visited the southern sludge treatment and recycling center in Yokohama's Kanazawa Ward, where some 4,000 tons of ash -- over 70 percent of the city's total -- is stored.
"If the amount overflows here, then sewage treatment facilities will come to a halt, and so will (the city's) water system lifelines. This is originally drainage water from homes. I want people to consider this an issue close to home," he said. In May, the amount of radioactive cesium detected in ash at the southern treatment center exceeded 5,000 becquerels per kilogram, but by the end of October the level was below 2,000 becquerels per kilogram.
Cement businesses are expected to consider receiving shipments again if the level falls below 300 becquerels per kilogram, but this will take time. "We're caught between cement users and local bodies," one cement business that accepts sludge said. "I want officials to explain to users that the products are safe and start accepting ash."

One big question is in my Mind since a long time:
How much Sewage "Fluids" is needed to to produce 1Kilogram of Sludge?
Is there a common Formula?

With all this hydrogen floating about and getting everywhere, I was wondering if there was some kind of heavy water "reactor" somewhere which went out of control.
Because they do not require uranium enrichment, heavy water reactors are of concern in regards to nuclear proliferation. The breeding and extraction of plutonium can be a relatively rapid and cheap route to building a nuclear weapon, as chemical separation of plutonium from fuel is easier than isotopic separation of U-235 from natural uranium.

I have never seen that May 7th film before, complete. It doesn't seem to let me download it on RP. Oh well, I took a bunch of screen caps. Not sure if this has been on the thread. A Sept PDF with charts of what officials knew March 12th [In Japanese]

As for unit 4 reactor well, I made a stupid mistake having watched too many videos in one sitting. I knew it didn't look like the reactor well should, but I thought maybe it was something that had been temporarily placed in the region during the reactor shroud work. In fact it was the cask area of the fuel pool that you mention, my mistake.
I have only read this thread once, all the rest is processing I am afraid. :-) In the early digital globe images there was steam coming from R1 I think. Maybe also in the old, old south end webcam there may be stuff in the distance.
which reminds me Q, Ive been meaning to ask, when going through the early stages of the disaster via this thread, did you ever come across anything relating to steam coming from R1. Ive been wondering a long time why R1 never seemed to contribute much steam in relation to R2-R4.
