Nuclear Power

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 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 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 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.

Development, Investment and Operation of Nuclear Power

SPIC owns a nuclear power capacity of 4480MW in operation and4740MW under construction as a majority shareholder and 1,080 MW in operation as a minority shareholder, including 6% equity of Qinshan NPP Phase II, 20% of Qinshan NPP Phase III and 30% of Jiangsu NPP. Besides, SPIC owns a number of reserved project sites in both coastal areas of China like Bailong in Guangxi, Lian Jiang in Guangdong, Lianjiang in Fujian and inland areas like Pengze in Jiangxi, Chisong in Jilin, Xiaomoshan in Hunan and Fuling in Chongqing.

 
Haiyang NPP

SPIC is the majority shareholder of Haiyang NPP, which plans to build six 1,250 MW AP1000 units in Haiyang County, Yantai,Shandong Province. Phase I (2×1,250 MW) of Haiyang NPP is one of the major carriers of China’s self-reliant program of Gen III NP technology, and Phase II (2 × 1,250 MW) is in preparation stage.

 
Hongyanhe NPP

SPIC and China General Nuclear Power Group (CGN) are equal controlling shareholders of Hongyanhe NPP, which is located in Wafangdian County, Dalian,Liaoning Province. The project is planned to build six 1,000 MW PWRs. By now, Units 1, 2 , 3 ,4have been in commercial operation . Units 5 and 6 are under construction in accordance with the schedule.

 
 
CAP1400 Demonstration Project

The demonstration project, invested and held by SPIC, located in Shidaowan of Rongcheng County, Shandong Province, is listed as the major R&D project of large-scale advanced PWR, with the plan of constructing two CAP1400 PWRs.

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

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. SPIC is in charge of the nuclear island (NI) BOP and conventional island (CI) EPC.

“Self-reliance program pays off—Mastering seven key technologies for AP1000 NI construction and installation
 
Transfer of AP1000 technology almost 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.

Localized AP1000 standard design complete

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 follow-up AP1000 projects.

Follow-up CAP1000 projects such as Phase II of Haiyang NPP, Phase II of Sanmen NPP and Phase I of Lufeng NPP are ready for construction.

 
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 10,000 MW.

 
Development and Promotion of CAP1400 Technology
Progresses in CAP1400 R&D

On the basis of China’s over 40 years of experience in R&D, design, construction and operation of NPPs, combined with the introduction of AP1000 technology, SPIC developed the larger passive PWR NPP, CAP1400, with independent intellectual property rights. CAP1400 development and demonstration project has been listed one of the 16 National Science and Technology Major Projects.

Key milestones of CAP1400 demonstration project
 
 
CAP1400 going global

The safe and advanced CAP1400 technology, together with China’s competitive advantages in manufacturing and experience in localization and industrialization, has attracted intensive attention from clients in other countries interested in nuclear power development.

SPIC is committed to the globalization of CAP1400. Up to date, the marketing of CAP1400 has achieved progress in South Africa and Turkey.

 
In December 2015,President Xi Jinping and President Zuma of South Africa witnessed the signing of the Project Management Cooperation Agreement for CAP1400 Project and visited SPIC’s exhibition stand.
 
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 156 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.
EPC for Gen III nuclear power projects

SPIC subsidiary State Nuclear Power Engineering Co. (SNPEC) has the National Certificate (Grade A) for Nuclear Engineering Supervision, the National Certificate (Grade A) for Equipment Supervision, and the Shanghai Municipal Certificate (Grade A) for Engineering Supervision of Mechanical and Electrical Installation.

SNPEC is responsible for the construction and management of four units of the AP1000 self-reliant projects (two for Sanmen and two for Haiyang) and AP1000 follow-up units (Lufeng NPP). It also undertakes the construction of CAP1400 self-reliant project, i.e. Shidaowan NPP.

Development of auxiliary industries for Gen III NPPs

To fill the gap of Gen III nuclear power technology, and promote the upgrade of China’s nuclear power industry,SPIC increased inputs into the fields of module manufacturing, nuclear-grade zirconium production, digital reactor protection system development, etc. and made great progress. SPIC has set up the world’s first dedicated plant for AP1000 CV and modules, which is capable of fabricating the integrated head package (IHP), personnel air lock,equipment hatch and penetrations, etc. SPIC also built the first production line of nuclear-grade zirconium in China.
