Note: Refer to 2007 TWG report for I&C systems applied in existing NPPs.

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.

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%.

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.

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Obsolete and shortage of spare parts for outdated component have been critical long term issues which operating plants have to work on and put much effort to improve the situation.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
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 & 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.
Issues & Topics – Utilities
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.
Issues & Topics – Utilities
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.
Issues & Topics – Utilities
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.
