摘要
Self-powered neutron detectors (SPND) play a key role in the monitoring of the neutron flux in the reactor core. In this research, a modified simulation method is proposed and realized in order to predict the performance of the SNPD that might be affected by a variety of parameters of the detector. Compared with the methods proposed by researchers in the past, this method involves more comprehensive physical processes, and it can be used to analyze the sensitivity and life-span of a practical detector under real reactor conditions. The research results are compared with the experimental results and show a relative error < 4%, better than the relative error of > 9% of past research.
