摘　　要：在第三代核电建设的过程中,严酷工况下的高端控制阀目前主要依赖进口,为保障三代核电项目核电厂建设的顺利实施,降低核电机组的建设和维护成本,上海市核电办公室走访调研了大量生产制造企业、高校、科研院所及工程建设单位,了解阀门产业的发展现状,对比分析现有技术和国际先进水平的差距。结合市场需求及紧迫程度,本文指出第三代核电严酷工况关键阀门国产化的主攻方向,并找到技术难点及突破点。基于上海地区的核电产业基础,为响应国家和地方的引导政策,本文提出了探索采用工业强基专项,整合各相关单位资源,促进优势互补,组织推进第三代核电严酷工况下关键阀门的国产化攻关。In the process of the construction of the third generation nuclear power plant, the high-end control valves under severe conditions are rely to import at present, In order to ensure the project smooth construction,and reduce the cost of construction and maintenance, Shanghai Municipal Nuclear Power Office visited a large number of manufacturing enterprises, universities, research institutes and construction enterprises to investigate the development of the valve industry, analyze the gap between the existing technology and the international advanced level. According to the market demands and urgency, main research direction and breakthrough point of technical problems are founded. Based on the nuclear power industry foundation in Shanghai, respond to the national and local guiding policies, It is proposed to use government support project,integrate the resources of relevant enterprises, promote complementary advantages, organize and promote the localization of key valves under severe conditions of the third generation nuclear power plant.
