三种高温气冷堆核能热力循环性能的比较

本文对三种新颖的核能联合循环系统进行了综合评价，从而揭示出过程的热力学完善性 并指出系统的改进方向。在建立公正、合理的比较条件的基础上，我们分析了系统关键参数对系统 性能产生的影响，得出如下结果：加湿型联合循环系统效率最高；比功输出最大的为余热锅炉型联 合循环；安全稳定性好是简单循环的主要特点。最终，我们可以得出这样的结论：选择何种透平排 热回收手段是影响系统性能的关键因素。以上工作对新型核能发电系统的研究提供了值得借鉴的 经验。

PERFORMANCE ANALYSIS AND COMPARISON OF THREE HIGH-TEMPERATURE GAS-COOLED REACTOR COMBINED CYCLE

This paper investigates three novel nuclear power systems employing combined cycle, for the purpose of revealing the system potential and indicating the guideline of amendment. On the basis of analysis, we clarified the features of each system: the efficiency of HHTCC is the highest within three; HTSTCC can produce the maximal power ratio; good stability and safety is the prominent advantage of NEBCC. Under standard conditions, the relationships between the key parameters and the performance of each system were pointed out. As result, the most important factor influencing the performance of combined cycle is in which way the heat from gas turbine was recovered. This fundamental study is useful to development of novel nuclear power generation system.
