欧洲铅冷快堆水平螺旋管式蒸汽发生器热工水力性能分析

以欧洲铅冷堆（ELSY）水平螺旋管式蒸汽发生器（HST-SG）为研究对象，结合其结构参数和运行参数，选取了合适的传热阻力模型开发了一维稳态热工水力计算程序，采用该程序首先对ELSY HST-SG进行校核计算，以验证程序计算的准确性，再结合计算结果，对ELSY HST-SG热工水力性能进行详细分析，并针对不同运行参数开展对比分析研究。分析结果表明，ELSY HST-SG各项参数选择合理，热工水力性能优良，结构紧凑。因此，该程序可用于ELSY HST-SG的设计开发和性能分析。 

Thermal-Hydraulic Performance Analysis of Horizontal Spiral Tube Steam Generator for European Lead-Cooled Fast Reactor

Taking the horizontal spiral tube steam generator (HST-SG) of European lead-cooled system (ELSY) as the research object, combined with its structural and operating parameters, this paper selects an appropriate heat transfer resistance model and develops a one-dimensional steady-state thermal hydraulic calculation program. Firstly, the program is used to check and calculate ELSY HST-SG to verify the accuracy of the program calculation. Then, combined with the calculation results, the thermal and hydraulic performance of ELSY HST-SG is analyzed in detail, and the comparative analysis and research is carried out for different operation parameters. The analysis results show that the selection of various parameters of ELSY HST-SG is reasonable, the thermal and hydraulic performance is excellent, and the purpose of compact structure is achieved. Therefore, this program can be used for design development and performance analysis of ELSY HST-SG.
