摘要:
核电厂热力系统设计需在保证安全性的前提下尽量提高经济性.经济性的影响因素较多,包括技术成熟度、设备成熟度以及系统热经济性等.为了从热经济性的角度确定最优的快堆核电厂热力系统加热器配置,以俄方800 M W钠冷快堆热力系统为参考,基于热平衡分析法建立了适用于快堆核电厂的加热器、立式汽水分离再热器等设备的热力分析模型,进而开发了快堆核电厂热力系统热经济性分析程序,利用俄方设计计算值进行了程序验证.利用新开发的程序研究了不同加热器布置方案、给水焓升分配方案,确定了等焓降分配法的给水焓升分配方案热经济性最好.
Abstract:
The design of the nuclear power plant thermodynamic system is to increase the economy of the plant while maintaining or improving safety margins .The economy of the plant is influenced by many factors including technical maturity ,equipment matu-rity and thermo-economy of the thermodynamic system . To determine the optimum configuration of re-heater ,using the Russian 800 M W sodium cooled fast reactor ther-modynamic system as a reference ,the physical model of re-heater and vertical moisture separator re-heater based on thermal equilibrium method was built and a thermo-economic analysis code was developed .To assess the development status of this code , benchmark calculations were performed with the Russian design values .Based on the reference system , the scheme of different re-heater arrangements and the scheme of different enthalpy rises were discussed .It is found that the equal enthalpy drop distribu-tion method is of the best thermo-economy .
