Nuclear power

Being one of China’s three nuclear power developers and operators as well as the leading nuclear power technology supplier, SPIC is appointed by the State Council of China to accomplish the introduction, assimilation and self-reliant innovation of Gen III nuclear power technology.

From researching and designing China’s first NPP (Qinshan NPP) and first overseas NPP (Chashma NPP in Pakistan) to developing the world-leading Gen III Passive PWR CAP1400, SPIC is becoming a competitive player in the global nuclear power industry.

State Nuclear Power Technology Corporation (SNPTC), an industry group with majority shares held by SPIC, is the platform for consolidating nuclear power assets and businesses, which primarily include:

Nuclear power investment, development, construction and O&M;

introduction,assimilation, R&D, application and promotion of Gen III nuclear power technology AP1000; implementation of national science and technology major projects, such as R&D, application and promotion of advanced nuclear power technologies like CAP1400 and small modular reactors; operation and lifetime services for NPPs, manufacturing of nuclear power equipment and materials, etc.

Nuclear Power Development and Operation

SPIC owns a nuclear power capacity of 4,480 MW in operation and 4,740 MW under construction as a majority shareholder. It is also the minority shareholder of 1,080 MW nuclear power assets in operation, including Qinshan NPP Phases II and III, Jiangsu NPP, etc. Besides, SPIC owns a number of reserved project sites in both coastal areas of China like Bailong in Guangxi, Lianjiang in Guangdong, Lian Jiang in Fujian and inland areas like Pengze in Jiangxi, Chisong in Jilin, Xiaomoshan in Hunan and Fuling in Chongqing.

Planning and layout of SPIC’s main nuclear power projects: By 2020, the installed nuclear power capacity under construction and in operation will both reach 10 GW.

 
Hongyanhe NPP

SPIC and China General Nuclear Power Group (CGN) are equal controlling shareholders of Hongyanhe NPP, which is located in Wafangdian, Dalian, Liaoning Province. The project is planned to build six 1,000 MW class PWRs. By now, Units 1 to 4 have been in commercial operation, while Units 5 and 6 are under construction in accordance with the schedule.

 
Introduction and Promotion of AP1000 Technology
Steadily proceed with the construction of self-reliant AP1000 projects

Four AP1000 units are being built in Sanmen, Zhejiang Province and Haiyang, Shandong Province (Units 1 and 2 of Sanmen NPP and Units 1 and 2 of Haiyang NPP), marking the largest Sino–US cooperation in energy technology.

Self-reliance program pays off—Mastering seven key technologies for AP1000 nuclear island (NI) construction and installation

SPIC has substantially localized the manufacturing of equipment and materials based on the experience gained during the assimilation of AP1000 technology and construction of self-reliant projects, and accomplished the localized AP1000 standard design (CAP1000 standard design) after enhancing the safety margin based on the lessons learned through the Fukushima accident, which strongly supports the big-volume construction of followup AP1000 projects。

 
Transfer of AP1000 technology substantially completed
AP1000 equipment and materials substantially localized

The average localization rate for the NI equipment of the four self-reliant project units reaches 55%, and that of the fourth unit, Haiyang Unit 2, reaches 72%。 Comprehensive mastering of the manufacturing technology of AP1000 key equipment has strengthened the capabilities of the whole nuclear power equipment manufacturing industry。

 
Development and Promotion of CAP1400 Technology
CAP1400 demonstration project

Development of Gen III Nuclear Power Industry Chain
Indigenous research and development of Gen III nuclear power equipment in the process

By organizing China’s equipment manufacturing enterprises, on the basis of technology introduction, SPIC strengthened localization of key equipment, overcame difficulties of independent innovation, and comprehensively mastered the R&D,design and manufacturing technology of key equipment and materials for AP1000 and CAP1400. SPIC leapfrogged from Gen II to Gen III, which strongly supported the big-volume construction and international marketing of Gen III NPPs.Holding the concepts of “openness, cooperation, inclusion and win-win”, SPIC cooperates with suppliers at all phases of Gen III NPP construction, and has established a complete qualified supplier management system.

Cooperating with American Society of Mechanical Engineers (ASME), Institute of Electrical and Electronics Engineers(IEEE) and other partners, SPIC leads China’s equipment manufacturing industry to follow the requirements for advanced nuclear safety culture, learn and apply international advanced industrial standards and improve quality assurance system。

As of today, SPIC has 159 qualified suppliers at home and abroad, covering six fields of machinery, electrical, materials,engineering, I&C and operation service. The AP/CAP Gen III nuclear power supply chain, globally oriented and shared by China and international partners, has been established.

SPIC has developed the capacity of supplying required equipment and materials for construction of six to eight AP/CAP nuclear power units per year.
