【日本《应用机械工学》1979年9月号报道】到目前为止,世界上已建成的核动力船共有6艘。美国的“萨凡纳”号从1962年5月开始进行试航,并纳入商业航行。在8年间,共航行了50万海里(相当于绕地球23圈)。于1970年7月停泊在查尔斯顿的海岸码头。“萨凡纳”号上的与核反应堆有关的设备,除了一台泵以外,全部被拆除,船 [Japanese Journal of Applied Mechanics] reported on September 1979] So far, there are six nuclear-powered ships built in the world. The “Savannah” of the United States began trial flights in May 1962 and incorporated commercial voyages. In eight years, a total of 500,000 nautical miles (equivalent to 23 laps around the earth) were sailed. It was anchored at the coast pier in Charleston in July 1970.
