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. 

大型先進壓水堆核電技術研發

自 20世紀90年代以來，中國核電企業按照更高安全要求在引進國外先進技術的基礎上持續改進，成功研發CNP1000、CPR1000二代改進型堆型，并實現了批量化建設。日本福島核事故后，中國核電企業在自主研發的ACP1000堆型和ACPR1000堆型的基礎上，研發出滿足當今國際最高安全標準的華龍一號技術。 

2006年，中國作出從美國西屋公司引進AP1000技術，建設中國第三代核電站的決策。通過組織實施大型先進壓水堆核電站國家重大科技專項，完成了自主三代國和一號的型號研發。

以華龍一號、國和一號研發成功為標志，中國核電實現了由“二代”向“三代”的技術跨越。
