MPSIS软件注锌模块的验证与敏感性分析

Background]Zinc-injection in primary coolant has been widely practiced in the world, and a lot of research has been carried out in China. The CAMPSIS software, which belongs to China Nuclear Power Engineering Co., Ltd. and has independent intellectual property rights, is developed for analysis of crud behavior in reactor core. And the CAMPSIS software has a zinc-injection module. [Purpose]This study aims at verification and sensitivity analysis of the zinc-injection module, and provide technical supports for engineering applications of the CAMPSIS software and the zinc-injection technology. [Methods]Based on the fundamentals of zinc-injection and the experience of international practices, combined with the characteristics of CAMPSIS software, the verification and sensitivity analysis of the zinc-injection module of CAMPSIS were carried out. [Results]It is showed that overall trend of the calculaiton results of CAMPSIS software about the crud mass of reactor core is basically consistent with the experimental results, the average relative deviation is -20.3%, and the sensitivity analysis results of zinc-injection concentration and zinc-injection cycle were in line with theoretical expectations.
