中子活化法标定反应堆临界装置相对功率

Relative Power Calibration on Critical Facility through Neutron Activation Method

介绍了利用中子活化法标定临界装置相对功率的方法。该方法可以标定临界装置的运行功率限值,并利用实验结果对MCNP程序的计算结果作校核分析,推测出最大功率以下任一功率指示值所对应的临界堆芯内平均绝对中子通量密度,对反应堆安全运行有重要意义。

The paper introduces relative power calibration method. The operational power limit can be calibrated on the critical facility through neutron activation through this method. MCNP calculation is checked by the experimental results of power calibration. Average neutron flux density under limit can be deduced from the calculation results. This is very important for the safe operation of reactors.
