电视新闻画面显示，一号反应堆爆炸发生于当地时间周六下午3点36分，灰色烟雾随即笼罩了核电站上空。东京电力公司称，四名在现场员工在爆炸中受伤。
At the time Mr Edano said the blast had “destroyed the roof of the outer building but the reactor containment vessel did not explode”.
当时，枝野幸男称爆炸“摧毁了反应堆外部建筑的屋顶，但反应堆容器没有爆炸。”
The level of radiation was higher than normal before the blast because engineers had been venting contaminated steam from the reactor vessel, in an effort to relieve pressure that had been building since the cooling system failed on Friday. The venting process triggered the explosion when combustible hydrogen released by the steam mixed with oxygen in the air, officials said.
在爆炸发生之前，核电站周围的核辐射水平就已经高于往常，那是因为反应堆冷却系统在周五因地震失效后，内部压力不断上升，工程师们不得不释放含有辐射物质的蒸汽为内部降压。日本官员说，正是被释放的蒸汽包含的可燃氢气在接触到大气中的氧气后，导致了那次爆炸。
Japan’s Nuclear and Industrial Safety Agency (Nisa) confirmed the presence of caesium and iodine, both radioactive elements, in the vicinity of Fukushima Daiichi Unit 1. Nisa reported an initial increase in levels of radioactivity around the plant earlier on Saturday, but these levels have been observed to lessen in recent hours.
