摘　　要：模块化小型堆(ACP100)的化学和容积控制系统净化模块是一个典型的多工况、多目标的系统模块。为了寻找化学和容积控制系统净化模块最优的调试/运行参数,本文构建了净化模块的热工水力模型和多工况、多目标优化模型,提出了考虑不同工况下泵流量和净化流量的目标函数和优化评价指标——综合偏离率。利用所构建的模型,以泵的小流量、模块初始净化流量为优化变量,对净化模块在寿期内的运行进行单因素分析和多目标优化分析。通过分析发现,在单因素优化条件下不存在一个在各种工况和各目标下均最优的调试点,但是多目标分析表明,在初始净化流量约为设计点的1.09倍、泵的小流量约为设计点的1.5倍时,全寿期运行的综合偏离率能从额定设计点的7.0%降至1.5%以下。敏感性分析也表明模型的多目标分析结果具有较好的适用性。Purification module of chemical and volume control system of ACP100 is a typical module with multi-objective and multi-mode. In order to find the best operation parameter, a thermal dynamic model and an optimization model have been built and connected. An objective function and an evaluation index have been proposed, which have considered the purification flow rate and pump flow rate under different mode. Using the connected model, the debug and operation of puri- fication module has been analyzed with decision variables of bypass flow rate of pump and initial purification flow rate of module. The results show that there is not a best debug point for all operation modes. However, based on multi-target optimization ,the integrated deviation rate can be reduced from 7.0% with designed debug point to lower than 1.5% with 1.09 times than designed initial purification flow rate and 1.5 times than designed bypass flow rate of pump. The sensitive analysis sho＇ns that the multi-objective optimization result is applicable for purification module.
