4. 4 Challenges to Chinese NPP I&C industry:  By 2007, 11 units in operation, but 5 types of reactor among them: 1.300MW PWR 2.600MW PWR 3.900MW PWR 4.700MW CANDU 5.1060MW 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. Nuclear Power in China

5. 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%.

15. 15 Activities ongoing-Sys. integrator Introduction on China local DCS System integrator Background: 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.

18. 18 Activities ongoing-Utilities Activities ongoing in NPP I&C area – Utilities Keep 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 Obsolete and shortage of spare parts for outdated component have been critical long term issues which operating plants have to work on and put much effort to improve the situation.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. 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.

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. 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. Issues & Topics – Utilities

26. 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.
