  • 现在沸水反应堆燃料组件特殊的因为核心的地方已经沸腾了需要一个保险措施,能让一个,燃料组件冷却并且得到

    Now BWR fuel assembly is unique in the sense that because we have boiling going on in the core there needs to be some assurance that every fuel assembly is getting coolant and getting water.

    youdao

  • 很快蒸发殆尽燃料部分露出冷却,这样将熔毁反应堆核心热量蒸汽散发出来。

    Soon, the water had burned off and the fuel rods were exposed -- allowing them to emit levels of heat and steam that can melt the reactor's core.

    youdao

  • 所以理解这些事情,它们能够中子反应堆中除去,能够设计一个核心位置了。

    So with an appreciation for the kinds of things that can take neutrons away from the system you then are in a position to design a core.

    youdao

  • 燃料虽然停止工作,仍然非常炙热,而且裂变反应生成多种副产物也会产生很多热量这些热量一直维持反应堆核心

    That's due to the heat that remains in the nuclear core, both from the recently-disabled but still-hot fuel rods and from the various byproducts of the fission process.

    youdao

  • 反应堆核心合金燃料融化时,需要2,200摄氏度高温同时释放大量辐射微粒

    This is when the uranium and the zircalloy fuel rods at the heart of the reactor melt. It occurs at temperatures above 2, 200c, releasing highly radioactive particles.
