美国阿贡国立实验室的脉冲反应堆试验装置(简称Treat)已于1959年2月23日达到临界,已能安全地产生很大的脉冲热中子流。最大积分中子通量超过10~(15)中子/平方厘米,可以用来研究快中子堆的燃料元件,直到这些元件的熔点。 堆芯的熔化说明快中子堆的安全性还有许多未知因素,脉冲反应堆试验装置对探索这些未知因素 The Pulse Reactor Experiment (abbreviated Treat) at the Argonne National Laboratory in the United States reached a critical mass on February 23, 1959, and was able to safely generate large pulsed thermal neutron fluxes. The maximum integral neutron flux of more than 10-15 neutron per square centimeter can be used to study the fast neutron reactor fuel elements up to the melting point of these elements. The melting of the core shows the safety of fast neutron reactor, there are many unknown factors, pulse reactor test device to explore these unknown factors
