Research and Analysis of External Steam Supply Process Scheme for Large Nuclear Power Units
Based on the industrial steam demand and route distance parameters around a nuclear power plant,combined with the technical characteristics of the nuclear power plant,the paper presented the overall technical scheme for external steam by steam conversion system using the nuclear energy of nuclear power plant as the heat source.It was proposed that the working temperature and working pressure of steam at the outlet of the conversion system as follows:270℃,1.8MPa.a.Based on the overall scheme,two process schemes(scheme one and scheme two)of steam conversion system were designed,and the two process schemes were compared from the aspects of system configuration and thermal capability,results showed that scheme two was simpler,the influence on the interface of plant was lower,and the economy was slightly better.The overall scheme and process scheme of steam conversion proposed in this paper can provide reference for nuclear energy steam supply project.
