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。
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.
安全壳内的空气具有相当的辐射性，工作人员最多只能曝露5个小时，否则就超过安全范围。
Its air has been so radioactive, a worker could be exposed only five hours before exceeding a safe limit.
内壳本身是略凹，所以圆屋顶在任何时间只有一部分直接接受太阳辐射。
The inner shell itself is slightly domed as only a section of a domed roof receives solar radiation directly at any time.
