中国先进研究堆首次临界实验

The First Critical Experiment of China Advanced Research Reactor

摘要: 首次临界对反应堆建设具有重要意义，标志着反应堆基本建成。本文介绍了中国先进研究堆首次临界实验的原理、方法、步骤和结果。在无参考堆，不进行零功率物理模拟实验的情况下，实验进程完全按理论计算的预期进行，向超临界过渡1次成功。实验结果与理论计算结果符合良好。

Abstract: The first criticality is one of the important mile-stones of nuclear reactor project. It means that the reactor has been erected successfully. The experiment principle, procedures and results of CARR first critical experiment were briefly described. Without referenced reactor and zero-power device, the process of experiment was according to the theoretical calculation. The experiment results are well in agreement with the neutronics design results.
