一种方法用在沸水式反应堆，要用2个东西。
现在，我们回顾一下沸水式反应堆，我们会做一个压水式反应堆。
Now let me go over boiling water reactors and then we'll do pressurised water reactors.
现在，两种在美国很普遍的类型，是压水式反应堆和沸水式反应堆。
Now the two types that are common in the United States are the pressurised water and the boiling water.
沸水式反应堆的压力大约在1000磅，那使得沸腾可以在核心这个地方发生。
The pressure in a BWR is about a thousand pounds which allows the boiling to take place in the core.
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。
And it originally started with boiling water reactors back in the late nineteen seventies where they had, for the pumps, they had debris screens.
这一个是很熟悉的，增压安全阀的疏忽打开，或者是在压水式反应堆的减压阀，或者是在沸水式反应堆的安全阀。
This one is the familiar one, inadvertent opening of a pressurised safety or relief valve in a PWR or a safety valve in a BWR.
你们可能使一个蒸汽发生器的管道破裂，也可能使一个仪器的线断裂，可能会得到管道破裂的光谱，在沸水式反应堆容器的里面。
You could break a steam generator tube, you could break an instrument line and you could have a spectrum of pipe breaks in a BWR inside of containment.
这是个沸水式反应堆和压水式反应堆的，设计上的重要区别，沸水型反应堆的燃料组件，是罐装起来确保我们得到，的冷水的供应足够。
This is a very important design difference between a BWR and a PWR. So, BWR fuel assemblies are essentially canned to make sure we have an adequate supply of cooling water.
我想要着重在沸水反应堆，也压水式反应堆。
And I wanna focus in on the boiling water reactor and the pressurised water reactor.
还有很清楚地，许多不同种的燃料组件，如你们会在一个沸水型，和加压水式反应堆看到的，燃料组件是不同的，所有产生在一个燃料针的，热量都需要除去。
And clearly, many different types of fuel assemblies, as you will see a BWR and PWR fuel assemblies are different and all heat that is generated in that one fuel pin needs to be removed.
还有很清楚地，许多不同种的燃料组件，如你们会在一个沸水型，和加压水式反应堆看到的，燃料组件是不同的，所有产生在一个燃料针的，热量都需要除去。
