AFP - Shares of TEPCO, which owns the plant at risk of Fukushima, plunged to a historic high at the Tokyo Stock Exchange on Tuesday because of the spill in the Pacific Ocean thousands of tons of radioactive water from the reactors Nuclear.
After 25 days of an uphill struggle to avoid an uncontrolled fusion fuels in rugged installations, the danger of a major disaster was still not excluded and environmental pollution worsened.
The title of TEPCO Electric Power (TEPCO) has unscrewed from 11.53% in mid-session, investors are increasingly doubting the ability of the utility to pay huge compensations that will be claimed.
The action dropped 51 yen Tuesday mid-day to fall to 391 yen.It even fell in the early morning to 376 yen, or prices lower than the lowest end of session for nearly 60 years.
"The compensation payments are likely to explode with the release of radioactive water," said a broker.
The course of TEPCO has loosened over 80% since March 11 closing in, weighed down by the cascade of explosions and leaks of contaminating stored in Fukushima Daiichi (No. 1).
The group also decided Tuesday to postpone to a date not announced its financial results for the fiscal year from April 2010 to 31 March, because the consequences of the disaster triggered by the devastating earthquake and tsunami in the northeastern Japan, told AFP spokesman.
Opposite the central operations of ocean dumping of 11,500 tonnes of radioactive water were continuing on Tuesday after starting the day at 19:00 (1000 GMT).
Expected to last for five days, these discharges 250 km north of the metropolitan Tokyo and its 35 million people, relate to a slightly contaminated water, assured Tepco.
The evacuation of this water in the ocean where the radionuclides are expected to concentrate, according to TEPCO, is imperative in order to free up storage tanks intended to be filled with highly radioactive water.
The fishing was prohibited within a radius of 20 km around the plant, corresponding to the exclusion zone on earth.
All power supply system of six reactors in Fukushima broke down March 11, stopping the pumps for cooling the nuclear fuel that was allowed to warm dangerously.
Technicians are now scrambling to repair this equipment is locked in a vicious circle: it is vital to cool the reactor fuel and spent fuel stored in tanks, but they use more water, more radioactive groundwater rise.And unless they inject water, the temperature increases in the reactors.
The "wash out" caused massive flooding in buildings and underground service tunnels, which are invaded by thousands of tons of radioactive water, which retards the progress of work to rehabilitate the electricity network.
Even if disposal of polluted water seems to have eclipsed the cooling, it was continuing Tuesday, thanks to huge concrete pumps sent from abroad.
Technicians also continued to try to plug a leak of highly contaminated water that has accumulated in a pit near the shore technical and empties directly into the ocean.
They try to understand where the water infiltrates, presumably coming from the reactor building 2.
"TEPCO will conduct drilling to follow the flow of water and inject water glass (sodium silicate)" to close access to the tank cracked, said Tuesday Hidehiko Nishiyama, a spokesman of the Security Agency Japanese nuclear.
More than three weeks after the tragedy, the results are still provisional police amounted to 12,321 confirmed dead and 15,347 missing.
