Three generations of nuclear autonomy bring opportunities

During the multi-national instrument and meter exhibition in Beijing on September 7, 2010, the 2010 user conference for measurement and control, instrumentation and automation sponsored by the China Instrument and Control Society was held during the Beijing Multi-national Instrumentation Exhibition. During the meeting, Wang Jun, chief engineer of China National Nuclear Power Technology Co., Ltd., named the "cooperation and win-win, and work together to promote the independent development of the third generation of nuclear power," and pointed out the direction of the instrumentation industry in the field of nuclear power.

After more than half a century of development, nuclear power has become a safe and clean energy source, which has greatly promoted the development of the world economy and society. Nuclear power and thermal power and hydropower equipment have become the three pillars of world power. China has made strategic decisions to introduce advanced metals, unify technological routes, and develop nuclear power from a high starting point. The National Nuclear Power Technology Corporation was established to take charge of the introduction, digestion, absorption, and re-innovation of AP1000's third-generation nuclear power. After 2020, China’s nuclear power will have a larger-scale development.

As a result, the independence of three generations of nuclear power has brought new opportunities and challenges to the instrumentation industry:

1) The new nuclear power plants all over the world use digital instrumentation control system platforms. 2) Since the Tianwan nuclear power plant was put into operation, nuclear power plants under construction in China are all using digital instrumentation technology. One of the important landmarks of AP1000 III nuclear power is the digital instrumentation system technology. Full application:

1) Computer-based fully distributed local network 2) Status diagnosis technology, intelligent alarm technology, database technology 3) Man-machine interface conforming to human factors engineering requirements, advanced control technology, fuzzy control technology, neural network technology, modern Modern technology such as simulation 4) Systematic control room function analysis and allocation, operator job analysis 5) Operator support system for nuclear power plant operating safety status, including computerized operation of intelligent diagnosis and intelligent alarm-based computerized operation Procedures and emergency response procedures.

The main features of the instrument control system of AP1000 nuclear power plant:

1) Measure and execute the driver layer for various types of equipment for power station parameter measurement and power plant control drive 2) Control and protection layer for calculation of power plant control and protection logic, output control instructions 3) Real-time data processing layer for collection Record all kinds of parameters and instructions of the power station. 4) Operation and monitoring layer. It is used by power station personnel to monitor the status of the power station online and perform operations.

The National Nuclear Power Technology Corporation, on the basis of advancing the joke and absorbing AP1000 instrument control technology, researched and developed the third-generation nuclear power digitalized instrument control systems and equipment with independent property rights, and provided complete instrument control systems, equipment and technical services for the mass production of nuclear power units.

The development of China's nuclear power plant in Nagano and the process of autonomy of the three generations of nuclear power digital instrumentation and control systems will bring an unprecedented opportunity and challenge to the instrument industry. We hope our complementary advantages, cooperation and win-win situation, and join hands in creating a better tomorrow.
