摘要

核反应堆的安全改进需要不断努力了解与裂变过程有关的基本物理量。在中子模型中,反应堆动力学被动力学参数所覆盖,以表征受扰动的中子居群的时间行为。反应器传递函数是这个时间描述的频域类比。它可以通过噪声分析或动力学调制的传递函数分析进行实验测量,用于反应器稳定性和动力学参数的研究。综述了通过动力学调制对反应器传递函数的实验测量。从反应堆物理研究开始,已经进行了大量的实验工作。概述了各种实验设计和进行的分析。本文还讨论了调制系统的概念。目前的工作仅限于在线内容和CEA Cadarache的内部档案,因为很难获得追溯到20世纪50年代的参考资料。

Review of kinetic modulation experiments in low power nuclear reactors
The safety improvement of nuclear reactors requires continuous efforts in understanding the fundamental physical quantities related to the fission process. In neutronic models, the reactor dynamics is covered by the kinetic parameters to characterize the temporal behavior of the neutron population subject to perturbations. The reactor transfer function is a frequency domain analogy of this temporal description. It can be measured experimentally through transfer function analysis via noise analysis or kinetic modulation, for the study of reactor stability and kinetic parameters. This paper summarizes the experimental measurements of reactor transfer function through kinetic modulation. Extensive work have been conducted experimentally, starting from the beginning of reactor physics research. An overview is given regarding various experimental designs and conducted analyses. The concepts of the modulation system are also discussed. The current work is limited to online contents and internal archives of CEA Cadarache due to difficulties in accessing references traced back to 1950s.
