containment shell

基本解释

The containment shell, around the nuclear—that is, highly radioactive—part of the nuclear plant is still something of a black box at the moment.
围绕核燃料的防护壳——极具放射性的物质——也就是核电站的一部分目前仍然在一个黑箱子里。
Nuclear power plant containment shell is a large-volume pre-stressed reinforced concrete silo-shell structure to prevent radioactivity, and is the most important protected object in special condition.
核电站安全壳是防止放射性物质向环境释放的大体积预应力混凝土筒壳结构，是特殊环境条件下的重点防护目标。
Shell added that it had placed containment booms into the surrounding waterways to stop the flow of oil.
壳牌石油补充说，他们已经在周围水域设立了控制栅栏，防止石油泄漏。

In like manner, I believe that reactors should be designed such that an earthquake of any magnitude could not destroy the reactor or its containment shell, further that if the reactor core was to start to melt down, the melt down itself would shut the reactor down and, at the very worst, the reactor would entomb itself with no potential release of radiation into the environment.
