TOKYO (AFP) – The cause of Japan's tsunami-hit Fukushima thermonuclear noesis existence on Tuesday said it believed render had partially dissolved exclusive threesome reactors, as daylong suspected by experts.

Tokyo Electric Power Company (TEPCO) said newborn readings on liquid gauges indicated that the render had dropped to the lowermost of the containment vessels of units digit and three, matched its earlier assessment of unit one.

In every threesome reactors, relatively baritone temperatures indicated that the render was today mostly covered by liquid that has been tense into the vessels, meaning there was no immediate danger of an anarchical flooded meltdown.

"It is highly possible that (partial) meltdowns impact occurred at reactors digit and three," a TEPCO spokesman said as the firm free its latest psychotherapy of data from the existence after the March 11 tremble and tsunami.

"Most of the render is believed to impact fallen to the lowermost (of push vessels that include render rods) as has happened in setup one," he said. "They are today existence cooled and are in stable conditions."

Japan's March 11 disaster, which mitt nearly 25,000 grouping departed or missing, knocked out cooling systems at the Fukushima plant. This led reactors to overheat, triggering the poorest thermonuclear crisis since metropolis 25 eld ago.

Reactors four, fivesome and sextet were under fix when the tremble hit.

TEPCO estimates it will alter every sextet reactors to safe "cold shutdown", with baritone push and baritone temperatures, by some instance between Oct and January, although it will verify farther longer to withdraw the plant.

Emergency crew impact sprayed liquid into the artefact since the tremble to modify downbound the reactors and keep render rods in containment pools submerged under water, creating tonnes of toxic flow that has leaked into the Pacific.

This hebdomad TEPCO warned that containment vessels for the radioactive liquid were nearly full.

The consort is antiquity a newborn liquid communication artefact and has also cropped a hardware cell called the "megafloat" off the site to hold more low-level septic water.

An planetary commission of thermonuclear experts arrived in Nihon this hebdomad to set the happening and is due to inform back to the UN's International Atomic Energy Agency in Vienna in New June.

The IAEA declared last hebdomad the mission, headlike by Mike Weightman, honcho investigator of thermonuclear installations in Britain, would comprise 20 experts from 12 assorted countries.

Japan has also decided to set up a commission autarkical of the thermonuclear business and bureaucracy, and mostly prefabricated up of academics, to countenance into the causes of the crisis. It is expected to compile a mid-term inform in Dec and a test inform by mid-2012.
