顶置燃气轮机核能联合循环系统开拓研究

EXPLOIT STUDY OF NUCLEAR COMBINE CYCLE SYSTEM WITH TOPPING BRAYTON CYCLE

本文探索研究核电站更新改造新技术．基于系统综合和能的梯级利用的思路，设计构筑压水堆核电站与燃气轮机相结合的核能联合循环系统流程超结构，通过对其综合优化，提出两种可供选用的顶置燃气轮机核能联合循环总体技术方案，还结合实例进行模拟分析，揭示了它们的热力学特性，从而提出核电站联合循环技术更新改造（ＮＲＣＣ－Ｒｅｐｏｗｅｒｉｎｇ）的新途径与新方案及其设计分析方法。

Nuclear combine cycle systems with topping Brayton cycle for existing nuclear power stations have been exploited in this paper. Based on the principle of energy cascades utilization and system synthesis, the system flow superstructure of the combine cycle has been schemed out and have been synthetically optimized, then two kind of system schemes have been put forward. At the same time, by setting up mathematical model with four independent variables for this system, we have pointed out the relationship between system performance and independent variables. These promising results obtained here will be valuable for NRCC-Repowering of existing nuclear power stations.
