Given the large quantity of irradiated nuclear fuel in the pool, the radioactivity release could be worse than the Chernobyl nuclear reactor catastrophe of 25 years ago.

由于池中有大量的辐照核燃料，放射性释放可能比25年前的切尔诺贝利核反应堆灾难更糟。

Once electricity is lost, the irradiated nuclear fuel could begin to melt down.

一旦电力用完，辐照核燃料会逐渐融化。

Without cooling water, the irradiated nuclear fuel could spontaneously combust in an exothermic reaction.

没有冷水，辐照性核燃料就会在放热反应发生的同时燃烧。

The Pakistan Atomic Energy Commission says the country's two plants both observe international safeguards which prevent irradiated fuel from being used in nuclear weapons development.

The irradiated fuel can then be unloaded from the reactor, the U-233 separated from the thorium, and fed back into another reactor as part of a closed fuel cycle.

Once the MOX fuel assemblies have been irradiated in commercial power reactors, the plutonium can no longer be readily used for nuclear weapons.
