目前,世界各国在反应堆事业的发展中,都取得了较大的进展,对各种堆型进行了较详细的研究和比较。其中水冷堆(压水堆和沸水堆)无论是发电还是舰船上用都取得了比较成熟的经验。水冷堆在目前和将来仍是反应堆发展的方向。特别是舰船上用更有其优越性,体积小,安全可靠。七一年美国有一百一十艘核潜艇,都用的是水冷堆。而且水冷堆仍有向高参数发展的可能性。
At present, all countries in the world have made great progress in the development of the reactor business and conducted a more detailed study and comparison on various reactor types. Among them, water-cooled reactors (pressurized water reactors and boiling water reactors) have gained relatively mature experience both in power generation and on ships. Water reactors are still the direction of development of reactors for the present and future. In particular, the ship with more advantages, small size, safe and reliable. In the year of eleventh, there are 110 nuclear submarines in the United States, all using water-cooled reactors. And water-cooled heaps still have the potential to develop into higher parameters.
