"(...)Those efforts include a move to possibly encase one or more of
the reactors in concrete, a last-ditch effort similar to what was
done after the 1986 meltdown at the Chernobyl nuclear plant in the
former Soviet Union -- considered the worst nuclear disaster at a
plant.
On Monday, an official with Japan's nuclear and industrial safety
agency told reporters that tests are expected to be conducted in the
afternoon on how to use what he called a "concrete pump engine."
The engine would pump a mix of mortar and water into the reactor's
spent nuclear fuel pool and containment vessel, the official said.
The pool contains nuclear fuel rods that could give off radioactive
material, if exposed and overheated, while the containment vessel is
a steel and concrete shell that insulates radioactive material
inside.
While he did not indicate when or even if the concrete pump would be
used, the official did say the target would be the plant's No. 4
reactor. In just over two hours on Monday morning alone, 13 fire
engines sprayed about 90 tons of water toward that reactor in an
attempt to cool it down.(...)"

Betonierung des Abklingbeckens vor Ort zu sein.
