The protective sheath for the reactors

For three months, resigns from the damaged nuclear plant in Fukushima
radioactivity. Tepco plans now before digesting a protective cover
over the reactors. Construction has already begun.
A spokesman for the Tepco presented at a press conference a model of
the planned construction of the destroyed reactor 1 (June 14, 2011)
In order to prevent the escape of radiation from the damaged nuclear
plant in Fukushima I, operator Tepco has begun to create covers for
the heavily damaged reactors. The plan is a giant steel structure
height of 54 meters, 42 meters long and 47 meters wide, as the daily
"Mainichi Shimbun" reported. Then a protective coat is fastened with a
resin-coated plastic. This roof and wall panels to enclose the reactor
airtight and thus isolate the radiation. At the same time prevent the
housing such that rain water enters the open reactors. It was under
consideration, whether the cover is also plenty of wind and earthquake
resistant.
To protect the workers against radiation, the parts of the housing in
the city about 50 kilometers away Iwaki are collected and assembled.
As "TBS News" reported, was the work for the erection of steel
structure on 13 Started in June.

Then the structure with a ferry to the nuclear plant is being shipped
crashed when using a 140-meter high giant crane, the steel casing is
placed into position quickly. According to the newspaper "Asahi
Shimbun" are blown away and work on the sleeves of the reactor I, the
roof of the hydrogen explosion, was to be completed in late September.
The mantle is a temporary emergency measure, as Tepco stressed. You
still looking for a long term solution. For example, the sarcophagus
at Chernobyl in steel and concrete.
Decontamination of contaminated water
Meanwhile, repair crews are in the Fukushima nuclear ruin before a
further important step to overcome the disaster stage. A facility for
the decontamination of the broth should be taken as possible on Friday
into operation, said the group operator Tepco to continue. With the
new facility, the large amounts of highly contaminated water to clean
the spill in the heavily damaged nuclear plant to cool the reactors.
Was successful in a test run with slightly contaminated water, the
cesium content to the desired level has been reduced, announced the
Japanese Nuclear. Tepco originally had wanted to use the system
earlier. There are, however, occurred among other things, water leaks
that had to be sealed.
