These rods, made of neutron-absorbing materials such as boron, mop up excess neutrons and quench the chain reaction.

这些控制棒，由能够吸收中子的物质——硼制成，它吸收多余的中子，使链式反应停止。

The reactor core which includes these rods, and the water it sits in, are contained within a thick steel pressure vessel.

这些燃料棒就是反应堆的核心，它位于水中，并包裹在厚厚的钢制压力容器中。

The nuclear fuel is encased in hard alloys to construct fuel rods; the reactor core that these rods make up, and the water it sits in, are contained within a steel pressure vessel.

核燃料的形式是在硬合金包裹下的燃料棒；并且这些燃料棒放在水中，外面还有一层钢压力容器。

These rods, while not as hot as the ones currently in the reactors, also require cooling water to prevent overheating that could lead to a meltdown.
