【摘要】 面对日益增长的核电发展需求,几乎所有的国家都把新的核电项目定位于第Ⅲ代核电技术,其中一个重要原因就是因为第Ⅲ代核电技术的安全性相对于第Ⅱ代和Ⅱ+核电技术的安全性有了很大提高。第Ⅲ代核电技术中的AP1000采用非能动安全技术,极大提高了安全性能指标。对AP1000与第Ⅱ代核电技术中具有代表性的安全系统,即AP1000中的非能动安全壳冷却系统(PCS)和第Ⅱ代核电中的喷淋系统(SCS),进行了比较,从概率安全评价(PSA)的角度对它们进行分析,通过具体计算得出了非能动安全系统具有比较优势的原因。更多还原

【Abstract】 With the increasing need of nuclear power,almost all countries who want to build new nuclear power plant take the generation Ⅲ technology as their first choice.The main reason is that the safety of generation Ⅲ technology has been improved greatly than generation Ⅱand Ⅱ+ technology.The passive safety technology is introduced by AP1000 and it is one of the best in generation Ⅲ technologies.The representative passive containment cooling system of AP1000 and containment spray system of generation Ⅱ nuclear power plant were compared in the paper and analyzed using probabilistic safety assessment method.The reasons of passive safety system possessing comparative advantages were obtained by the concrete calculation.更多还原
