小编摘要:福岛第一核电站2号机组传出爆炸声。

 

日本经济产业省的原子能安全保安院今天(15日)上午8点前召开记者会透露,今天上午6点10分福岛第一核电站2号机组传出爆炸声。

保安院就有消息称控制压力池这一设备破损一事表示:"目前具体情况还不清楚。如果出现破损缺口,那么液体或气体就会从破损的地方泄露出来。"

控制压力池这一设备连接着核反应堆的覆盖容器,能将核放射性物质等封闭在反应堆内部。该设备的部分体机出现破损,很可能会影响其封闭放射性物质的功能。

另外,保安部还透露,2号机组的核燃料棒露出水面约2.7米,露出长度约相当于核燃料棒的一半左右。

另外,东京电力公司会见记者透露,经检测今天上午8点31分,福岛第一核电站正门附近检测到的核辐射量为每小时8217mSv。这一数值相当于人类1年内所能承受辐射当量正常标准的8倍多。东京电力公司在爆炸声传来后,让正在现场作业的该公司员工暂时撤退。

今天早晨,日本内阁官房长官枝野幸男会见记者时透露,福岛第一核电站2号机组控制压力池出现破损,但枝野同时表示,"周边核辐射数值没有出现急剧上升的情况",因而认为现在的状况不会立即损害周边居民的健康。

Japan's Nuclear and Industrial Safety Agency says an explosion was heard early Tuesday morning at the No.2 reactor of the disaster-hit Fukushima No.1 nuclear power plant.

Agency officials told reporters that the blast was heard at 6:10 AM local time on Tuesday.

Chief Cabinet Secretary Yukio Edano earlier told a news conference that a reactor facility, called the suppression pool, has been damaged.

But agency officials said they have no detailed information yet about the report.

They said that depending on where the damage is done, either liquid or air could leak out of the suppression pool.

The suppression pool is linked to the reactor containment vessel and is designed to prevent radioactive material from leaking outside.

Experts say a breach to this crucial facility has raised the possibility of a radioactive leak.

The Nuclear and Industrial Safety Agency also said that nuclear fuel rods inside the No.2 reactor are exposed above water by about 2.7 meters. That's about half the length of the fuel rods.

Agency officials said that radiation levels around the nuclear power plant reached 965.5 microsieverts following the explosive sound.

They say the figure later dropped slightly to 882 microsieverts.

The officials said they believe the rise in radiation level is due to the breach in the suppression pool, but that they cannot say for sure. They said they are monitoring the situation closely.

The officials added that the monitored level of radiation would not immediately pose a health threat.

Tokyo Electric Power Company that operates the power station briefly evacuated workers from the facility following the sound of the blast.
