The world's first CAP1000!
Two key nuclear power equipment have been successfully delivered; Assist in taking nuclear power autonomy to a new level
Recently, Dalian Dagao Valve Co., Ltd. (hereinafter referred to as Dalian Dagao) has achieved an important delivery milestone - the independently developed CAP1000 "PV64 Main Steam Isolation Valve" and "PV70 Explosion Valve" have successfully completed acceptance and delivery work. The successful delivery of these two nuclear grade key equipment marks a solid step forward for China in the field of nuclear power key equipment localization, injecting the power of "Chinese chips" into the construction of the world's first CAP1000 unit and laying the foundation for the promotion of fourth generation nuclear power technology. As one of the key equipment of Unit 3 of Sanmen Nuclear Power Plant, the CAP1000 main steam isolation valve is a national major scientific and technological project achievement that has been jointly developed by Dalian Dagao, State Power Investment Corporation Shanghai Nuclear Engineering Institute and other units after years of research and development. This valve is responsible for the critical mission of quickly shutting off and preventing core melting within 2-5 seconds under severe accident conditions. It can operate stably for 60 years in high temperature environments, with a safety level of nuclear grade 2 and seismic resistance meeting SSE (6g) requirements. All performance indicators have reached the international level of similar products.
As one of the key equipment of Haiyang Nuclear Power Unit 3, the CAP1000 blasting valve has completely independent intellectual property rights and technology, meeting the high reliability operation requirements of harsh environments such as high temperature, high humidity, and high radiation in nuclear power, and reaching the international advanced level.
Under the guidance of the national "dual carbon" strategy, Dalian Dagao has always adhered to technological innovation as the core, continuously cultivated in the fields of nuclear power and new energy, deepened cooperation among nuclear power enterprises, promoted the localization and substitution of more key equipment, and contributed greatly to the high-quality development of China's nuclear power industry.
