TEPCO announced on September 9 that 6 workers entered the reactor building of Reactor 3 at Fukushima I Nuclear Power Plant, and installed a water gauge to measure the amount of contaminated water in the basement. According to the company, the radiation exposure of the 6 workers was between 0.33 to 5.26 millisieverts. The measurement using the water gauge is set to start on or after September 12.
...一方、東電は１０日から３号機、９月中に４号機の原子炉建屋上部のがれきの撤去を始める計画を明らかにした。３、４号機原子炉建屋上部には損傷した天井や外壁が重なっており、撤去によって放射性物質の拡散抑制につながるとしている。
... TEPCO also disclosed the plan to start removing the debris from the upper floors of Reactors 3 and 4. The work will start in Reactor 3 on September 10, and it will start in Reactor 4 within this month. Upper floors of Reactors 3 and 4 are littered with damaged ceiling panels and exterior wall panels, and it is hoped that the spread of radioactive materials will be suppressed by removing the debris.
Hmmm. Removing the debris will stir up the radioactive materials instead of suppressing them, won't it? Not to mention exposing the workers to an inadvertent 10-plus sieverts/hour super hot spot, as it happened near the exhaust stack between Reactors 1 and 2?
From the tweets by the worker at Fukushima I Nuke Plant, it is evident that TEPCO is fast running out of money (to spend on the accident, apparently not on its retiring executives) and carbon-based workers to do further work. The worker also tweeted a week or so ago that the construction people were active, already clearing debris in Reactor 4.
