Vienna (Writing and agencies) .- Japanese engineers have managed to connect an external power cable to the reactor 2 of the Fukushima nuclear plant, but have not yet returned the flow of energy to the plant, according to the International Atomic Energy (IAEA). "The Japanese authorities have informed the IAEA that the engineers have been able to connect an external cable to the power supply unit 2," the UN agency said in a statement.
The IAEA said it aims to "reconnect power to the unit 2, after spraying water on the reactor building of Unit 3 is complete." The UN agency says the irrigation of reactor 3 was stopped at 11.09 GMT, without specifying details. The return of electricity would be a positive step in the work to start the reactor cooling system, which like the other five of Fukushima was damaged after the earthquake and subsequent tsunami on Friday.
The IAEA has already pointed out in recent days that the reactor containment vessel 2 is partially damaged, entailing a risk of radioactive leakage. Andrew Graham, scientific advisor to the director general of the IAEA, Yukiya Amano, today told reporters in Vienna that the situation remains "very serious", although it has not worsened since Wednesday.
The reactor 4 of the atomic plant is one that involves "major concern", said since nothing is known about the level of water in the pools of spent nuclear fuel. It also ignores the temperature of water in these pools from March 14, when it was 84 degrees Celsius, so that IAEA experts do not rule out that since then has started to boil.
According to the data handled by the UN nuclear agency, reactors 1, 2 and 3 are "relatively stable", while water levels in the vessels of safety in reactors 5 and 6 "are down," said Andrew. Particles first U.S. weather experts predicted that the first radioactive isotopes from the central Japan could reach the U.S.
west coast on Friday 18, although at doses harmless to health, according to Los Angeles Times. It is estimated that the first toxic waste leaked into the air in Fukushima would have gone over the 8,000 miles of distance that separates Japan from the U.S. mainland pushed by the currents of the upper layers of the atmosphere.
According to reports, the Environmental Protection Agency United States has prepared a hundred network of radiation sensors distributed throughout the country and is not expected to detect any anomaly until Friday, although particles as those took a week to cross the Pacific after a North Korean nuclear test in 2006.
However, in a press conference at the White House, the U.S. president. UU., Barack Obama, has said that his country expected to reach its shores harmful levels of radiation. "
