Boiling water reactors are somewhat different and we'll discuss in greater detail how these systems work but let me just contrast them for you.
沸水反应堆是有点不同的，我们会在详细的讨论这些系统是如何，工作的，但是让我将它们进行对比。
And it originally started with boiling water reactors back in the late nineteen seventies where they had, for the pumps, they had debris screens.
它最初开始时沸水式反应堆，在1970年代晚期，那里他们有，对于泵而言，他们有碎片屏幕。
In operation since the early 1970s, Japan's Fukushima Daiichi nuclear plant USES six boiling water reactors, which rely on uranium nuclear fission to generate heat.
从19世纪70年代投入运行以来，日本福岛第一核电站利用六个沸水堆，通过铀核裂变来产生热能。
Tepco said at about 2:46 p.m. local time Units 1, 2 and 3 at its Fukushima Daiichi plant -- three of six at the plant -- shut following the earthquake. All are boiling water reactors.
