核电站二回路系统中冷凝器的质量和尺寸是影响核电站总体重量、体积及布置等的重要因素.利用传热经验公式和冷凝器工业性试验结果,建立了冷凝器热工水力数学模型,编制模型评价程序来验证模型的精确性,对冷凝器体积受冷却管外径、节距等设计参数影响的敏感性进行了分析,并利用不同的优化算法对冷凝器体积进行优化设计.结果表明:采用改进的自适应遗传算法能使冷凝器有更好的性能,冷凝器体积明显减小;冷凝器体积的减小能使整个核电站二回路布置更加紧凑,减小二回路事故的发生率,也便于冷凝器的设计制造.
The quality and size of the condenser in the secondary circuit of the nuclear power plant are the important factors affecting the overall weight, volume and arrangement of the nuclear power plant.Based on the heat transfer empirical formula and the condenser industrial test results, the thermodynamic and hydraulic mathematical model of the condenser is established and the model Evaluation program to verify the accuracy of the model, the condenser volume by the cooling pipe diameter, pitch and other design parameters of the sensitivity of the analysis and use of different optimization algorithms for optimal design of the condenser volume.The results show that: The improved adaptive genetic algorithm can make the condenser have better performance and the volume of the condenser decreases obviously. The reduction of the condenser volume can make the layout of the secondary circuit of the whole nuclear power plant more compact and reduce the incidence of secondary loop accidents, Condenser design and manufacture.
