AFR-100钠冷快堆超临界CO_(2)循环结构布置与性能分析

Layout and system performance analyses of supercritical CO_(2) brayton cycle for AFR-100

本文以先进钠冷快堆(AFR-100)作为热源对象开展超临界CO_(2)循环系统的结构布置与性能分析。利用热力计算程序分析了简单回热循环、再压缩循环和部分冷却循环下的超临界CO_(2)循环热力系统,获得了设定参数条件下最佳的热效率以及各主设备运行参数。再压缩、部分冷却循环较简单回热循环均能有效提高系统热效率约2%,分别可达37.81%和37.59%。对于AFR-100,再压缩、部分冷却循环均为适用的循环结构,能够获得较高的系统热效率同时系统结构和部件设计更为合理。

Aim to the Adavanced Fast Reactor(AFR-100)as the heat source,this paper studied on the laytout and system performance analyses of supercritical CO_(2) Brayton cycle.Via the thermodynamic anlaysis program,the recuperation cycle,the recompression cycle and the partical cooling cycle were calculated and the optimal parameters,the highest thermal efficiency were gained.Compering with the recuperation cycle,both efficiencies were improved about 2%on the recompression cycle and the partial cooling cycle,as 37.81%and 37.59%respectively.For AFR-100,the recompression cycle and the partical cooling cycle are suitable layouts both on the higher cycle thermal effiency and the more reseasonable system structure and component design.
