His team could work close to the reactor. In Japan it may well be too dangerous to do so because of high levels of radiation.

三里岛事故处理工作组可以靠近反应堆工作。而在日本，由于放射性太强，要这样做很可能非常危险。

This, we now know, is what "well prepared" looks like: total loss of power at the Fukushima Daiichi nuclear reactor, which deprived the reactor core and spent-fuel pools of cooling water.

现在我们都知道，所谓“准备地最充分”就是这样：在福岛大一针核反应堆完全丧失电力供应，使核反应堆中心装置和核废料池冷却水中断供应。

Considering the critical components like reactor coolant lines and oil-well casings, the metal parts are subjected to prior replacement, for safety, with respect to a worst-case analysis of failure.

考虑到关键部件如反应堆冷却剂线和油井涂层不能出现问题，为了安全，并对失效做了最坏的分析，这类金属零件会得到优先更换。
