AZUZ: It's a modern marvel of engineering. Reportedly, the largest movable object constructed on land, a dome tall enough to cover the Statue of Liberty and wide enough to cover the U.S. Capitol building.

阿祖兹：这是现代工程奇迹。据报道称，一个世界上最大的可移动拱门正在修建，其高度足以覆盖自由女神像，宽度足以覆盖美国国会大厦。

But it's not being built to house tourists, sports or businesses. It's for the remains of a reactor at the Chernobyl nuclear power station. It's located in Ukraine. When it was online in the 1980s, it was part of the Soviet Union. A disaster there exactly 30 years ago was the worst in the history of nuclear power.

但是这座拱门并不是为了旅游业、体育业或商业而建。它是为了切尔诺贝利核电站的反应堆遗址而建。这座核电站位于乌克兰。上世纪80年代，当它出现在网络上时，它还是前苏联的一部分。30年前，这座核电站发生了核电史上最严重的灾难。

An experiment gone wrong caused explosions and blew the roof off Chernobyl's number four reactor. Thirty people died immediately, but scientists estimate that thousand of cases of radiation sickness and cancer deaths will have resulted as well.

实验失误引发爆炸，炸毁了切尔诺贝利核电站4号核反应堆的屋顶。爆炸造成30人当场死亡，但是科学家估计，这起事故还会导致上千人因放射性疾病和癌症死亡。

After the accident, a giant steel and concrete cover was built to seal reactor four and contain some of its radioactive material. But it's deteriorating and radiation is leaking out. So, the $1.7 billion dome called the New Safe Confinement is being built to cover it.

事故发生后，修建起一个钢筋混凝土保护层，用来密封4号核反应堆，防止放射性材料扩散。但是这个保护层逐渐退化，导致辐射泄漏。所以，为保护4号核反应堆，修建了这个耗资17亿美元的“新安全保护罩”。

Engineers plan to use rails to slide it over the current structure this November and to finish sealing it off by the end of next year. Workers are constantly monitored for radiation exposure.

工程师计划在今年11月，用钢轨将拱门滑到现有结构之上，然后在明年年底前完成密封工作。工人们仍在继续监督辐射暴露情况。
