摘要

核电机组燃料成本低

无污染物和二氧化碳排放

因此核能机组供热能更好满足我国社会经济发展的需要。本文以AP1000三代百万核电机组为例

对高压缸排汽抽汽、再热热段抽汽等2个供热方案进行了对比分析

并介绍了各抽汽方案对机组经济性、安全性等方面的影响。结果显示:高压缸排汽抽汽方案的经济性最优

具有更好的综合技术经济性。

Abstract

Nuclear power units has low fuel cost

zero pollutant and carbon dioxide discharge

using nuclear power unit to supply heat can better meet the needs of social and economic development in China. By taking an AP1000 third generation million-kilo watt level nuclear power unit as an example

this paper compares and analyzes two heat supply schemes including high-level extraction and hot re-extraction extraction

and introduces the influence of each extraction scheme on economy and safety of the unit. The results show that

the high-discharge extraction scheme is the most economical scheme and has a better comprehensive technical economy.
