Fortunately, the radioactivity of spent fuel—and therefore its ability to generate heat—drops fairly rapidly in the first few days and weeks after it is removed from the core.
所幸，乏燃料棒的辐射量及其产热量在开始几天和移出反应核之后的几周里都在不断下降。
Although fuel costs have fallen sharply, core consumer prices, which exclude the volatile categories of food and energy, still rose by 2.8% in the year to October.

Excluding food and fuel, the so-called core rate was unchanged, capping the smallest 12 - month gain in four decades.
扣除食品和燃料，过去12个月的核心消费价格指数维持不变，是40年来最缓慢增幅。
About ten of these are stacked high in the core and there's I don't recall exactly how many but these become the fuel assemblies.
大约有10个是堆放在核心的地方，还有，我不记得具体有多少，但是这些已经变成了燃料组件。
According to Goldman's index, core consumer prices, which exclude the volatile categories of food and fuel, are rising in some 70% of countries.
根据高盛指数，不计算食品和燃料的核心CPI在70%的国家中上升。
Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core.
Messier27 (M27)是个气体发射星云的典型例子，它是由于类似太阳的恒星耗尽了其核心的核燃料而产生的。
The core personal consumption expenditures price index, which excludes food and fuel, rose 1.3 percent in May from a year earlier.
不包括食品和汽油的核心个人消费支出物价指数在5月份比去年同期增长了1.3%。
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。
As the star begins to run out of fuel, its core becomes smaller and hotter, boiling off its outer layers.
当恒星逐渐缺少能源，它的核心部分变得越来越小，温度逐渐升高，同时使外层物质挥发。
Core consumer price inflation, which excludes the volatile categories of food and fuel, has accelerated, to 2.6% at an annual rate in the three months to February.
除去食品和能源两个价格不稳定的类别，核心消费价格增长加速，到二月为止的三个月中，已经达到2.6%的年增长率。
A meltdown occurs when nuclear fuel rods cannot be cooled, thus melting the reactor core and causing a release of radioactivity.
如果核燃料管无法降温，就会发生熔毁，到时反应器的内核也会熔化，从而引起核泄漏。
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。
If the core melts and the pressure vessel bursts (and eventually melts), it will catch the molten fuel and everything else.

Inside the core itself, "there is likely no water level," the assessment says, adding that as a result, "it is difficult to determine how much cooling is getting to the fuel."
堆芯内部的“冷却水可能已经蒸发殆尽”，评估报告还说，“无法确定究竟有多少冷却水到达了核燃料所在的位置”。
