1958年12月美国国立爱达荷反应堆试验站的特殊动力试验堆SPERT-Ⅲ开动了,SPERT型反应堆共有三个,SPERT-Ⅲ是其中之一,这类反应堆是美国原子能委员会的安全研究计划以内的试验性反应堆。反应堆SPERT-Ⅰ已在1955年投入运行,专门用来研究非均匀加浓铀水堆可能发生的事故,SPERT-Ⅰ反应堆在运行中有极尖锐的功率峰,颠值功率可高达280万瓩,但是这样高的功率所维持的 In December 1958, SPERT-III, a special dynamic test reactor at the National Idaho Reactor Experimental Station in the United States, was started. There are three SPERT reactors, one of which is SPERT-III. Such reactors are within the US Atomic Energy Commission’s safety research program Experimental Reactor. The reactor SPERT-Ⅰ was put into operation in 1955 and was devoted to the study of possible accidents in the UHCWR. The SPERT-Ⅰ reactor had a very sharp power peak in operation with an up-peak power of up to 2.8 million 瓩, But such a high power is maintained
