我想問下,核反應堆有何用?

核反應堆主要有以下幾部分及其應用：
fuel rods燃料棒: consists of enriched uranium含濃縮鈾. Fission核裂變 will occur in these fuel rods releasing large amounts of energy釋放能量.
control rods控制棒: inserted into the reactor反應堆 to control控制 the fission reaction. These rods absorb neutrons吸收中子 and so interrupt the chain reaction阻礙連鎖反應.
Water:
-acts as moderator減速劑 to slow down the neutrons resulting from a fission and make them be captured easily by uranium nuclei鈾核 to continue the chain reation.
-acts as coolant冷凍劑 to absorb heat from the fuel rods and transfer heat to a secondary water circuit through a heat exchanger.

其實,太陽所以能夠發光發熱,都是因為其本身是個核反應堆.目前世界各地的商用核反應堆超過430個,供應的電力佔全球人口所需電力的百分之十七。 這些核反應堆利用鈾或鈽的原子核分裂而發電。我們希望它不要利用這些設施,進行軍事用途,例如發展核子武器。
