Challenges to Chinese NPP I&C industry: By 2007, 11 units in operation, but 5 types of reactor

among them:1. 300MW PWR2. 600MW PWR3. 900MW PWR4. 700MW CANDU5. 1060MW VVER

Lack of human resource and knowledge accumulation:• Engineers spreading out concentrating at different I&C system

specific to each type of reactor, thus experiences narrowed. • Much more knowledgeable experts needed to support regulator.

No time to recall, digest and “asking why” before being driven to a new era.


5

Policy and Planning: Policy changed from “properly development” to

“actively promoting”. By the year 2020, NPP installed capacity will

targeting at 40 GWe, accounting for 4% of total installed electric power supply nationwide. And NPP of 18 billion KWe under construction in addition.

Recent study on national NPP program planning shows, 75 GWe, accounting for 5% of Total capacity is expected by 2020, still far from world average level 17%.

Activities ongoing-Sys. integrator

Introduction on China local DCS System integratorBackground:As Chinese government established the policy to actively develop the nuclear power industry, efforts on Self-reliance of DCS system integration, localization of the equipment manufacturing and making the technical service and spare parts supply for operating plants locally available, have been one of the major factors to assure the state nuclear power program to be realized and sustainable.

To meet the demands of government policy, three major players in china nuclear power industry, CNNC(China National Nuclear Corporation), CGNPC(China Guangdong Nuclear Power Corporation) and SNPTC(State Nuclear Power Technology Corporation Ltd) have established the companies respectively in the past few years, relying on the ongoing projects, to accept Tech. transfer and progressively to become a qualified DCS system engineering and integrating supplier.

Activities ongoing-Utilities

Activities ongoing in NPP I&C area – UtilitiesKeep on management of NPP I&C obsolete, aging and upgrading, improving reliability, accuracy and life time of NPP I&C system and equipment.

Continually improve equipment management system for various I&C equipment and devices, to enhance the performance monitoring and status data collection, paying much attention on reliability issues.

Obsolete and shortage of spare parts for outdated component have been critical long term issues which operating plants have to work on and put much effort to improve the situation. Most plants have launched aging management project and start to collect aging data of I&C. Together with these activities, the effort also are put on establishing the upgrading plans for NPP life cycle.

19

Activities ongoing-Utilities

Activities ongoing in NPP I&C area – Utilities (Cont.)Optimizing preventive maintenance program of NPP I&C, and establishing maintenance plans for NPP life cycle. Preventive maintenance system is more and more important along with the increasing of plant operating time. Plants have developed the preventive maintenance program and carried out the maintenance and repairing work based on this program, and will keep on optimizing the program with collected performance status data and defects statistics.

Integrating the activities of the equipment management and the preventive maintenance program, to make maintenance work more pertinent, efficient and actually effective, which is expected to result in a prolonged reliable operating time of I&C system.

Issues and Topics - Engineering

23

Issues & Topics – Sys integrator

Issues and Topics by system integrator:•Consulting on comparison and application between EU and USA standards regarding to the safety classification and respective practical qualification requirement and methods on 1E digital platform and IEC61513 class 2 and 3 equipment.•Guides on period testing method, configuration and system parameters to be examined in 1E digital system.•In-depth technical discussion on feasibility of implementing bidirectional communication between Safety and non-safety digital systems through network.•Practice and method for V&V of 1E digital system development platform and tools.•Practice on reliability analysis and V&V of 1E SW platform.

24

Issues and Topics by utilities:•Site elements seals maintenance After analysis on Equipment defects statistics, seals of site sensor element and driving component are major weakness causing leakage. Sharing of method and requirement on its repairing or maintenance practice of other NPP is needed.•Spare parts rules for new I&C Due to the very fast upgrade or replacement of obsolete I&C equipment, and failure modes of new one are hardly obtained in time, it is difficult for maintenance department to define the rules and scope of spare parts.

Issues & Topics – Utilities

25

Issues and Topics by utilities : (Cont.)•Preventive maintenance for DCS HW&SW Preventive maintenance activities for digital control system seem only limited to general periodic functional testing and cleaning. What should be done with this respect for in-depth preventive maintenance on hardware and software?.•Analogue I&C Performance monitoring A workshop needs to be held to share the best practices on performance monitoring, and Surveillance, diagnostics, and prognostic methods of NPP analogue I&C systems.


26

Issues and Topics by utilities : (Cont.)•Study or practices sharing on engineering of DCS online maintenance Technologies of computer network, server, workstation, power supply, and redundancy engineering of critical component and power module of digital control system have made it possible to perform maintenance work on line for DCS. A platform supported by IAEA to do the in-depth engineering analysis on the feasibility and technical constrains is appreciated, in order to establish the specification to the engineering of signal distribution and power supply, and the requirement to the manufacturing on modules, wirings, switches, heat dispersion component.


27

Issues and Topics by utilities : (Cont.)•Practices on DCS FAT, installation, commissiong and SAT All the new built NPPs in China will be installed with digital control system, for which DCS system FAT, site installation, commissioning and SAT will take place in 2011 to 2014. Workshop in 2010 sponsored by IAEA on best practices in those areas would be appreciated.•I&C aging management IAEA to provide technical support and guidance on I&C aging management in the operating plant, with respect to techniques and methods of mechanism analysis, monitoring, screening out and counter measures.


28

Issues and Topics by utilities : (Cont.)•NPP suppliers list and Technicians & experts list The facts that the original I&C were supplied by foreign manufactures who may be no longer maintaining the production of the outdated component, or may have been bankrupted and no longer exist, have caused difficulties for operating plant to have long term, stable and in time spare parts supply. IAEA is recommended to generate an updated manufactures list by product or system, which shares the information of companies who have ever been or are being NPP suppliers, and to collect and establish a global I&C technicians and experts contact list together with the brief introduction of their organization and products or systems being used for communication and information exchange.
