The structure of dry - type air - cote current - limited reactor designed by optimizing is reasonable and the cost is minimum. Practical problem about optimum design is conquered.

利用优化设计得到的干式空芯限流电抗器结构合理、耗材最少，并就优化设计的具体问题进行了实际解决。

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。

But despite all that, the reactor vessels have held, and radioactive release is limited.

但是尽管发生了这一切不幸，反应堆外壳并没有破裂，放射性物质的泄漏也非常有限。

In the case of the previous two events, the reactor vessels themselves weren't damaged, and officials said only limited radiation leaked out.
