摘　　要：本文通过对比CEFR、BN800以及CFR600启动和停堆冷却系统的功能设计,分析它们的优缺点及可能存在的问题,最后提出CFR600启停系统相关设计优化建议,到达优化CFR600启扩运行方式,有效避免启扩超压,提高运行可靠性的目的。同时简化水汽转换操作,为后期实现水汽转化自动控制奠定工艺基础。This paper compares the functional design of CEFR,BN800 and CFR600 start-up and shutdown cooling systems,analyzes their advantages and disadvantages and possible problems.Finally,it proposes the design optimization of the system of CFR600 to reach the optimized CFR600.The start-up operation mode effectively avoids the purpose of opening and expanding overpressure and improving the operational reliability,and at the same time simplifies the water vapor-conversion operation,laying a technological foundation for the later realization of automatic control of water-vapor conversion.
