摘要
"华龙一号"采用177组先进燃料组件、先进的堆芯测量系统和反应堆冷却剂系统,提高了核电厂的固有安全性和堆芯热工裕量。在系统设计方面,配置了能动和非能动相结合的安全系统,核电机组具有完善的超设计基准事故、严重事故应对措施。"华龙一号"采用单堆布置、双层安全壳,实现了布置优化和实体隔离,有效降低了安全系统共模失效问题。这些设计使得"华龙一号"安全性达到了三代核电技术的先进水平。
The 177 fuel assemblies, advanced in core instrumentations and reactor coolant system, are adopted in ＂Hualong One＂ . The inherent safety of reactor and the thermal margin of reactor core have been improved. Active ＋ passive safety system are used in ＂Hualong One＂ , and diverse approaches am available in ＂Hualong One＂ to perform safety functions both in DBA and BDBA/SA conditions. Single unit layout and double-shell containment providing physical separation, and reducing interaction between units.These design characteristics meets the latest requirements of third generation PWR.
