Japan says that reactor can have broken 2, with radioactive release

TOKYO - Japan's nuclear crisis intensified again Wednesday, with Japanese authorities announced that a containment vessel in a second reaction unit in the northeastern Japan knit Fukushima Daiichi plant ruptured and released radioactive steam release. This would be the second ship in two days might be affected.

Japanese television showed, which apparently gets to steam out reactor No. 3 at the Fukushima Daiichi site about 10 am on Wednesday.

The ship had seemed completely get the last line of defense against large-scale releases of radioactive material from the reactor to be, but it was not clear how serious the possible injury might be.

The announcement came after Japanese broadcasters live shots of thick plume steam over the plant showed.

Yukio Edano, Chief Cabinet Secretary, said that the Government believed that the steam from the reactor No. 3 was in the part of surrounding containment vessel building blew an explosion on Monday.

The reactor has protection in three layers: the building; the ship containment and the metal casing to fuel rods, which are in the reactor. The Government has said that these rods in the reactor No. 3 is probably already damaged.

A spike in the levels of emissions in the works for the steam rises some of the relatively few workers in the factory leave was forced indoors, withdraw some to keep cool critical efforts to pump water in several reactors continue.

Early in the morning reported that a fire was burning only hours after officials said company that runs the plant, on a different reactor, flames that broke out Tuesday had been poured over.

A government official in Japan's nuclear regulatory agency soon after said that not more visible, but he warned flame and smoke, that it was unclear whether the fire in the reactor No. 4 building, died from was. He was also not clear if it was a new fire or still the fire Tuesday never way out.

There are a total of six reactors at the plant.

The developments are memories of the difficulties that the company is disturbing the plant, which has suffered several explosions since Saturday, to bring under control. And the confusion happened a symbol for days of often contradictory reports about the plant.

The company, Tokyo electric power, says that it can certainly know what is happening in many cases, because it too dangerous for workers too close to some reactors to get.

The situation was especially dire on Tuesday, as releases of radiation led the company to draw most of their employees from the plant.

Main concerns of the authorities are pools for spent nuclear fuel rods to several reactors in this work, including reactor No. 4, where the pool has lost some water to the fuel rods to keep stable. The stakes are still radioactive, and potentially as hot and dangerous as the fuel in the reactors.

Minoru Ogoda, the official of Japan's nuclear regulatory agency, a proposed plan use helicopters said unlikely sought patents to more cold water.

The hole or holes in the roof by a previous blast not large enough to sufficient amounts of water in allow appropriate, he said.

He said, electric would probably try Tokyo, spraying you water in the reactor building through a gaping hole in the wall blasted open by the explosion.

This explosion on Tuesday was caused by hydrogen gas bubbles up from chemical reactions set off by the fuel rods in the pool, Japanese officials said. Inspectors of the United States nuclear regulatory Commission said that she had said of the Japanese authorities that what burned oil machines close to lubricate the pool was.

Concern about the memory pools on two other types of reactors, no. 5, and 6 remained high. None of these three reactors at the plant, 140 miles worked on Friday afternoon, northeast of Tokyo, when an offshore earthquake with a magnitude 9.0 now estimated that shook website. A tsunami minutes rolled into the North-East coast of the Japanese later, that the plant flooded replication data.

At least 750 employees were evacuated rupturiert the inner control building at the reactor number two in the Daiichi plant, which crippled by the Friday earthquake and tsunami on Tuesday morning after a separate explosion. A wave of radiation published the closely spaced but seemingly random explosions in reactors No. 2 and 4 together 800 times more intense than the featured hourly exposure limit in Japan.
