The reporter recently learned from the China Nuclear Energy Association that the approval, editing and printing of 101 energy industry nuclear power standards such as the “Design Requirements for Nuclear Safety of Nuclear Power Plants in PWR Nuclear Power Plants†have been completed by the end of September this year and are expected to be approved by the National Energy Administration. Post release implementation.
This series of standards was researched and formulated by the Nuclear Industry Standardization Technical Committee (referred to as the Standards and Technics Committee) under the auspices of the Nuclear Industry Standardization Institute, and was approved at the second meeting of the Standards Committee held in late October this year. This marks that the construction of the standard system for pressurized water reactor nuclear power plants in China has taken substantial steps and laid the foundation for the establishment and improvement of China's nuclear power standard system.
Relevant persons of the association revealed that among the 101 standards, four nuclear power engineering economic standards such as “Nuclear Power Plant Engineering Construction Budgeting Method†have filled the gap in this field, and “Non-destructive Testing of Nuclear Power Plant Nuclear Equipment†has unified different tests. The method and acceptance criteria, more than 30 nuclear island mechanical equipment and material series standards such as "Stainless Steel for Nuclear Power Plants in Pressurized Water Reactors" are of great significance for promoting the localization of nuclear power equipment and materials.
Qian Zhimin, deputy director of the National Energy Administration, said: "Nuclear power standardization is of great significance to promote the independent development of nuclear power in China." He also suggested that top-level design work should be done to establish a standard system for nuclear power.
Zhang Huazhu, chairman of the China Nuclear Energy Industry Association, said that nuclear power standardization is a bottleneck that has plagued China's nuclear power development for many years. The release of this standard is of great significance for the establishment of third-generation nuclear power standards. "This will enable us to repeat the embarrassing situation that the second-generation nuclear power has not had its own standards for a long time in the construction of the three-generation nuclear power."
A nuclear power analyst believes that AP1000 (third-generation technology) is the future direction of China's nuclear power development, because its safety and efficiency are higher than those of previous generations, and the technology of CAP1400 units in China's nuclear power equipment export plan. It is derived from the AP1000. The reporter interviewed Shan Guoguo, director of the Institute of Economics and Energy Supply and Demand of the State Grid Energy Research Institute. He believes that China's nuclear power development route will also focus on the development of third-generation nuclear power technology on the premise of ensuring safety.
At the "2011 Nuclear Power Sustainability Summit Forum" held earlier, some insiders expressed the view that although the nuclear accident in Japan caused the domestic nuclear power development to slow down, the policy supports the future "safe, green and efficient" development of nuclear power. He Guang, chairman of China Guangdong Nuclear Power Co., also revealed to the media at an industry conference last month: "At present, the safety inspection and evaluation work of nuclear power plants under construction and in operation has come to an end, and safety inspection reports are being formed; "Nuclear Safety Planning", The two plans for the Medium- and Long-Term Development Plan for Nuclear Power are being advanced and are expected to be completed by the end of the year."
According to authoritative sources, by 2020, the installed capacity of nuclear power in China will not be less than 60 million kilowatts, which means that it has increased by more than five times on the basis of the current installed capacity of nearly 12 million kilowatts.
Copper is a versatile and important material in various industries. It is a soft, malleable, and ductile metal that is a good conductor of electricity and heat. Copper has been used by humans for thousands of years, and it still plays a critical role in modern society.
One of the main advantages of copper is its excellent electrical conductivity. It is used extensively in electrical and electronics applications, such as wiring, power transmission, and printed circuit boards. Its thermal conductivity is also very high, making it suitable for heat exchangers and cooling systems.
Copper is also important in the construction industry. Its corrosion resistance, durability, and aesthetic appeal make it an ideal material for roofing, gutters, and plumbing systems. Copper is also used in architectural features such as decorative panels, wall cladding, and sculptures.
Copper is also an essential material in the manufacturing of various products. Its mechanical properties and workability make it ideal for manufacturing pipes, tubes, wires, and other hardware components. Copper alloys, such as brass and bronze, are used to make a wide range of products, including musical instruments, jewelry, and coins.
Moreover, copper is an environmentally friendly material. It is completely recyclable, and recycled copper can be used to manufacture new products without any loss of quality. Recycling copper also saves energy and reduces the need for mining, thereby conserving natural resources and reducing greenhouse gas emissions.
In conclusion, copper is a versatile material with many advantages. Its excellent electrical and thermal conductivity, durability, workability, and recyclability make it an essential material in various industries.
