燃料棒
Of greatest concern are the spent fuel rods stored at reactor Nos. 3 and 4. They are not contained in the same kind of vessel as active fuel rods.
最令人担心的是3号和4号机组那些用过的燃料棒。它们并未和那些在用燃料棒一样使用同样的保存容器。
Instead, spent fuel rods in the U.S. are currently stored in underground pools of water or in dry-cask storage, where older fuel is put into steel cans filled with inert gas and then stored in silos.
相反,目前美国把用过的燃料棒存放在地下的水池里或装在干桶里,其中年代较远的燃料被放入充满惰性气体的钢罐里,然后存放在废弃的洲际导弹发射井中。
Overheating fuel rods then discharge gaseous forms of certain volatile radioactive elements, including cesium, iodine, strontium and tellurium.
然后过热燃料棒释放出某些气态易挥发放射性元素,比如铯、碘、锶和碲。
Attempts to build a single repository in the Nevada desert have failed over the past 30 years, so spent fuel rods are stored in liquid pools at each of the 104 reactors across the country.
在内华达沙漠建造一个仓库的尝试已经失败了有30年之久了,因此用完了的燃料棒被储存在全国104个反应堆的液体池中。
Mixed oxide fuel rods are partly made of plutonium. These fuel rods are partly exposed.
混合氧化物燃料棒含钚,这些燃料棒已经部分暴露。
The excessive stockpiling of fuel rods at Fukushima only arose because pressure from anti-nuclear groups has made the safe dispersal of nuclear waste so difficult.
福岛之所以堆积了如此多的燃料棒仅仅是因为来自反核组织的压力让核废料的安全疏散面临巨大困难。
This is a known and anticipated process, but the amount of hydrogen gas produced was unknown because the operators didn’t know the exact temperature of the fuel rods or the water level.
这个过程是被预见的,但是大量的氢气是否会产生无法预测,因为操作员并不知道燃料棒的确切温度,也不知道水位线到底多高。
Of greatest concern are the spent fuel rods stored at reactor Nos. 3 and 4.
最令人担忧的是存放在3号和4号反应堆的用过的核燃料棒。
As water levels dipped, fuel rods were likely exposed to air, increasing the chances of melting-and of a catastrophic meltdown.
随着水位下降,核燃料棒有可能暴露在空气中,从而增加了反应堆融化的可能性。
It「s the latest in a series of attempts including the use of helicopters to drop water to stop the fuel rods from overheating and causing a nuclear disaster.
这是一系列努力中最新的一项,另外还包括利用直升机喷水来防止燃料棒过热,防止造成核灾难。
Workers at the plant are trying to keep all fuel rods under water, which cools the rods (thereby preventing fires and explosions) and blocks radiation.
核电站工人正在尝试将所有燃料棒浸入水中,这样可以冷却燃料棒(阻止发生起火爆炸),阻断辐射。
The fuel rods are bundled together in the core of the reactor.
燃料棒被束在一起放置于反应堆的核心。
The company stores spent fuel rods on its premises because there is no consensus on where else to put them.
公司在经营场所储存了大量的废弃燃料棒是因为没有就它们的存放点达成一致意见。
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.
燃料棒虽然停止工作,但仍然非常炙热,而且裂变反应生成的多种副产物也会产生很多热量,这些热量一直维持在反应堆的核心。
They plan to encapsulate depleted fuel rods - unlike France there is no reprocessing here - in copper-coated cast-iron canisters.
他们计划将耗尽的燃料棒封装进铜涂层的铸铁罐——而法国人没有进行再加工。
They warned that if the tanks run dry and leave the fuel rods exposed, the rods could melt or catch fire, creating potentially lethal levels of radiation.
专家警告,如果池水蒸干,燃料棒暴露在外将会熔化或者着火,这样会产生致死的辐射强度。
If the fuel rods became damaged they would release radioactive material into the remaining coolant.
如果燃料棒损坏,放射性物质会进到剩余的冷却剂中。
