中国又一技术世界领先!或接棒高铁走向海外(图)

2016-12-16 20:32:53   央视新闻

全球首台AP1000核电机组——浙江三门核电站1号机组,12月15日正式进入性能测试的最后阶段,这也是该机组在装入核燃料前的最后一项工作,按照计划该核电机组预计2017年上半年并网发电。

全球首台AP1000核电机组测试进入尾声

浙江三门核电站1号机组单机容量125万千瓦,所采用的三代核电技术AP1000,比目前普遍使用的二代核电机组在安全指标上提高了近百倍,并且核电机组的寿命可以延长20年,达到60年。

与正在运行的电站设备相比,AP1000在系统构建中做了大量的“减法”,管道减少80%、电缆减少70%,大幅减少各个设备环节发生损坏、故障的概率,提高了整个核电站的可靠性。AP1000还采用了非能动的设计理念,即在发生严重事故时,无需人工干预,能保证核岛安全长达72小时。

更先进的核电重大专项示范工程将开工

不仅如此,在AP1000核电技术的基础上,我国自主研制的第三代压水堆核电重大专项CAP1400示范工程,目前已经通过国家核安全局的安全评审,预计于2017年一季度获批在山东荣成石岛湾开工建设。

即将建设的CAP1400核电机组,是我国通过引进、消化、吸收世界先进三代核电技术AP1000的设计理念,自行研发的具有我国自主知识产权、功率更大的先进核电技术,也是我国16个国家重大科技专项之一。跟AP1000相比,CAP1400对核反应堆及所有主设备都进行了全新的设计。

CAP1400核电技术的反应堆、主设备、安全系统都经过了大量的实验验证,不仅功率更大,同时进一步增强了核电站抗击地震、外部水淹等极端自然灾害的能力。此外,CAP1400核电机组的单机容量达到150万千瓦,能力更大,经济性也更好。

核电自主化带动产业升级

从引进AP1000,到自主研发CAP1400,中国核电在三十多年的时间里完成了从技术引进、消化、吸收到再创新的发展历程,为我国装备制造业的整体水平提升、核电装备和关键材料的升级换代提供了重要技术支撑。

上海电气核电集团总工程师唐伟宝在核电工程领域工作了30多年,1982年大学毕业之后,他就参加了我国第一台核电机组——秦山一期核电机组的建设。
