There were fears that an explosion at reactor unit 2 May have damaged the containment vessel, which increases the risk of release of hazardous radioactive materials.
有人担心2号反应堆发生的爆炸可能已经损坏了保护罩，从而增加了核泄漏的风险。
The lack of a containment structure for the Chernobyl reactor, whichmight have limited the emission of radioactivity into the atmosphere after theexplosion, is only the most glaring example.
切尔诺贝利核电站的反应堆没有安全壳结构，安全壳结构本可以在爆炸后限制辐射气体排放到大气中，所以，切尔诺贝利核电站就是安全壳结构缺失的最佳反例。
Chernobyl's reactor lacked a containment facility, unlike the Fukushima plant, whose GE-made containment vessels have withstood both an earthquake, tsunami, and thus far, a partial meltdown.
切尔诺贝利核电站的反应堆缺少防范设施，而福岛核电站有美国通用制造的防范设施，而且福岛核反应炉已经经历了一场地震和一场海啸，迄今为止，也只是部分核心熔毁而已。
With the primary containment vessel of reactor 1 still too full of steam, the radical decision was made to flood it with sea water to absorb the heat.
由于一号反应堆中最重要的密闭容器中充满了蒸气，因此临时决定用海水对其进行冷却，以便吸掉过多的热量。
In reactor 1, and later in reactor 3, steam contaminated with some radioactive elements was allowed out of the pressure vessel and into the larger containment vessel that surrounds it.
