发展阶段原子能的发展历史可简略分为四个阶段。第一阶段包括五十年代中期。这个时期出现了第一批原子能电站和现有的各种反应堆类型。每二阶段从五十年代末期到六十年代末期。这段时间由于原子能电站设备价值昂贵,反应堆功率低,一些国家又发现了大型石油天然气产地,因此与热电站比较竞争能力低。原子能电站的发展陷入低潮。第三阶段从六十年代末期到七十年代上半期,由于反应堆建设领域的发展(出现了新的,较 The development of atomic energy history can be briefly divided into four stages. The first phase includes the mid-fifties. The first atomic power plants and various existing reactor types emerged during this period. Every second stage from the late fifties to the late sixties. During this period, due to the high cost of equipment for nuclear power plants and the low reactor power, some countries have found large oil and gas producing areas and are therefore less competitive with thermal power plants. The development of atomic power station is at a low ebb. The third stage from the late 1960s to the first half of the 1970s, due to the development of reactor construction (new, more
