“华龙一号”全球首堆穹顶即将吊装 有望打破“首堆必拖”魔咒

国际在线报道(记者 肖中仁):中国核工业集团负责人24日透露,中国首个自主三代核电技术“华龙一号”的全球首个核反应堆示范工程穹顶将于25日或26日择机吊装,实现主体工程从土建转向全面安装阶段。“华龙一号”是全球唯一按计划进度建设的第三代压水堆,有望打破“首堆必拖”的魔咒。

“华龙一号”是中国自主创新,拥有完整自主知识产权的三代核电技术。2015年5月和8月,“华龙一号”在巴基斯坦和中国福建的4个示范工程分别开工建设。

其中,“华龙一号”示范工程在福建福清的核电5号机组建设进展顺利,将于25日、26日择机完成穹顶吊装。中核集团“华龙一号”总设计师邢继介绍说:“穹顶吊装完成以后,整个核岛的土建已经接近尾声,大量的设备可以引入到核岛,(后续)安装工作可以全面展开。所以穹顶吊装在各国核电建设里面约定俗成,把它作为一个重大的工程里程碑。”

在国际上,新核电技术的首台机组建设风险大、难度高,工程建设常常遭遇拖延问题。“华龙一号”全球首堆示范工程开工以来,各个工程节点均按期或提前完成。关键设备比如反应堆的压力容器、蒸汽发生器、主泵、汽轮发电机组等制造周期长的设备,工作进展也符合预期。中国核工业集团副总经理俞培根介绍说,从中国的技术、设计和设备成熟度,以及建设经验来看,“华龙一号”有望打破“首堆必拖”的魔咒,“中核集团‘华龙一号’国内外四台示范工程进展有序,各关键工程节点均按期或提前实现,是全球唯一按照计划进度建设的三代压水堆核电工程,我们有信心打破首堆‘必拖’的魔咒。”

俞培根还透露,“华龙一号”国产化率85%以上,中核集团已经做好“华龙一号”批量化建设准备。截至目前,中核集团已成功向7个国家出口过6台核电机组、8台反应堆或核动力装置。在为各国提供安全清洁能源解决方案、促进当地环保和人员就业的同时,还实现了合作共赢。俞培根说:“按照目前我们在国际上已经出口的核电机组来看,每一代核电机组可直接带动的产值大概是300亿人民币左右,相当于30万辆汽车的价值。如果考虑到核燃料运营、维修、退役等全产业链的贡献,以60年来计算,单台核电机组全寿期可以直接带动超过1000亿人民币的产值。”

目前,中核集团正积极参与“一带一路”倡议,一大批核电及产业链合作正在积极推进。比如,巴基斯坦核电项目建设顺利,阿根廷核电项目落地在即,中核集团还与美国、乌克兰、哈萨克斯坦等国探讨核燃料合作,参与法国核工业重组也取得了阶段性成果。英国政府今年年初正式受理了“华龙一号”的通用设计审查(GDA)申请,这一审查素有“全球最严核电审查”之称。
