Large Advanced PWR R&D
Since the 1990s, Chinese nuclear power companies have developed Gen II+ reactor designs – CNP1000 and CPR1000 – that meet more stringent safety requirements, on the basis of continuous improvement on imported advanced foreign technologies, and have acquired the capacity for batch construction. After the Fukushima nuclear accident in Japan, Chinese researchers developed the Hualong One design that meets the existing highest international safety standards, based on China's proprietary ACP1000 and ACPR1000 reactor designs.
In 2006, a decision was made to import Westinghouse AP1000 technology for building Gen III nuclear power plants. A national project for building large advanced PWR plants was launched. The research phase of a Gen III reactor design – Guohe One (CAP1400) – has now been completed.
Successful development of Hualong One and Guohe One represents a leap from Gen II to Gen III in nuclear power development.
大型先进压水堆核电技术研发
自 20世纪90年代以来，中国核电企业按照更高安全要求在引进国外先进技术的基础上持续改进，成功研发CNP1000、CPR1000二代改进型堆型，并实现了批量化建设。日本福岛核事故后，中国核电企业在自主研发的ACP1000堆型和ACPR1000堆型的基础上，研发出满足当今国际最高安全标准的华龙一号技术。
2006年，中国作出从美国西屋公司引进AP1000技术，建设中国第三代核电站的决策。通过组织实施大型先进压水堆核电站国家重大科技专项，完成了自主三代国和一号的型号研发。
以华龙一号、国和一号研发成功为标志，中国核电实现了由“二代”向“三代”的技术跨越。
