R&D on ZH-65 steam generator of HPR1000

HPR1000 is the third generation PWR technology with independent intellectual property rights. This paper introduces the independent R&D of ZH-65 steam generator, which is the key equipment of reactor coolant system in HPR1000. The R&D includes design research, software development, design verification test and key materials development. ZH-65 SG technically reaches the level of the third generation PWR nuclear power plant, and has completely independent intellectual property rights. ZH-65 steam generator is a bright pearl of HPR1000. The R&D achievements of this type of SG have been applied to the K2 and K3 project exported to Pakistan and the project of Fuqing 5&6. The 3 sets of ZH-65 SG for K2 project have been accepted in July 12th this year, and will surely create good economic and social benefits. (authors)
