摘　　要：中国实验快堆作为我国第1座快堆,于2010年7月21日取得首次净堆临界,完成一系列物理启动试验之后逐步取得冷态临界和热态临界。在临界试验过程中,采用了用控制棒进行临界外推的方法,顺利完成了3个状态的临界外推过程。临界试验的分析结果表明所采用的方法是合理有效的,且针对试验的相关理论计算结果是准确的。首次临界和冷态临界的最终临界状态下控制棒棒位的试验结果与理论计算结果的对比表明,两者符合良好。As the first fast reactor in China,the first clean core criticality of China Experimental Fast Reactor（CEFR） was achieved in 21st July,2010,and then the cold criticality and hot criticality after a series of physical start-up tests were achieved.All the three criticality tests were fulfilled successfully and safely using control rod extrapolation method.Results of the tests testify the effectiveness and reasonability of the method and calculation results used for the tests.The comparison of control rods position between calculation and tests for the clean core and cold criticality shows good agreement.
