300 Nuclear Power Standards to be Implemented at the End of the Year for Nuclear Power Construction

The approval, editing and printing of 101 nuclear power standards for the energy industry, including the “Planning Requirements for Nuclear Structure-related Steel Structures in PWR Nuclear Power Plants,” have been completed by the end of September this year and are expected to be implemented after approval by the National Energy Administration.

This series of standards was researched and formulated by the Energy Industry Nuclear Power Standardization Technical Committee (abbreviated as the Standardization Technical Committee) contracted by the Institute of Nuclear Industry Standardization, and was approved at the second session of the second session of the Committee of Standardization Technical Committee held in late October of this year.

Zhang Huazhuo, chairman of the China Nuclear Energy Industry Association, stated that nuclear power standardization is a bottleneck that has plagued China's nuclear power development for many years. The issuance of this standard is of great significance for the establishment of a third-generation nuclear power standard. "This will enable us not to repeat the embarrassing situation that the second-generation nuclear power does not have its own standards for the three generations of nuclear power construction."

The nuclear power equipment standards have further improved the autonomy of the nuclear power standard system and have always been a bottleneck that has plagued the development of nuclear power in China. In order to establish a sound nuclear power standard system as soon as possible, the National Energy Administration issued the “PWR Nuclear Power Plant Standard System Project Table” in 2009, which is the nuclear power industry standard. This is a combination of nuclear power in the field of national standards, industry standards in one nuclear power standard system.

After the release of the PWR Nuclear Power Plant Standard System Project Table, the National Energy Administration issued a total of 470 sets of nuclear power (nuclear island) standards for the formulation, revision and scientific research tasks in 2009-2011. The nuclear power standard system Construction began to increase speed. As of the end of September 2011, 680 standards in the PWR Nuclear Power Plant Standard System Project Table have been issued and implemented 101 items, 458 items are being developed and revised, and 300 items will be completed by the end of the year. The remaining standards will be 2012. In the year of completion, the standard system for the second generation of improved PWR nuclear power plants has been basically established.

In the revised nuclear power standard system, there are a total of 826 standard items in the eight major areas (29 sub-fields): general and basic, preliminary work, engineering design, equipment, construction, commissioning, operation, and decommissioning. Three hundred new special standards for three generations of passive pressure water reactor nuclear power plants have been added, and 33 new shared standards have been added to the second generation of improved and three generations of non-dynamic pressurized water reactor nuclear power plants to further improve the standard project of the second generation of improved pressurized water reactor nuclear power plants. .

Among them, the “Nuclear Power Plant Project Construction Budget Preparation Method” and other four nuclear power engineering economic standards fill the gaps in this field. “Non-destructive testing of nuclear power plant nuclear equipment” harmonizes different detection methods and acceptance standards. More than 30 nuclear island machinery equipment and material series standards such as stainless steel used in nuclear power plants are of great significance in promoting the localization of nuclear power equipment and materials.

While fully implementing nuclear power standard formulation and revision, in order to incorporate the latest technology of nuclear power engineering construction and the experience of China's nuclear power engineering accumulation and feedback into the standard, the PWR nuclear power plant standard system is undertaken by the Nuclear Industry Standardization Institute. The project list (2011) was also carried out at the same time.

Gong Jun, director of the Institute of Standardization, said that the revision of the project schedule aims to establish a nuclear power standard system that can meet the needs of the second generation of improved and three generations of non-reliable PWR nuclear power plants.

The nuclear power sector is expected to restart next year. Prior to the nuclear accident in Fukushima, Japan, countries have suspended the approval process for nuclear power projects. However, with the continuous improvement of the nuclear power standard system, the nuclear power equipment construction that has suffered much criticism may usher in a new round. The development opportunity.

Zeng Shaojun, secretary-general of the All-China Federation of New Energy Chambers of Commerce, previously told China Union Business Daily that nuclear power is favored by many countries because of its comparative advantages in low cost of power generation, long hours of power generation, stable grid access, and zero carbon emissions. , occupy a pivotal position in the energy structure of each country. After the nuclear leakage in Japan, only Germany proposed to abandon its nuclear program. The United States, Russia, and France still strongly support the development of nuclear power. In China, nuclear power can be relied on for nuclear power, and the development of nuclear power will not stop there.

It is understood that since the opening of nuclear power equipment around the year 2000, China’s nuclear power technology has made considerable progress. The world’s most advanced third-generation nuclear power technology, the AP1000, was first built in China, and China has gradually become a major nuclear power and power. According to the existing plans under construction, the installed nuclear power capacity in 2015 will reach 39 million kilowatts. The construction scale of nuclear power during the “Twelfth Five-Year Plan” period will remain unchanged, and the estimated “13th Five-Year” nuclear power construction will depend on the follow-up industry. Policy and nuclear power construction capabilities.

According to statistics, the installed capacity of nuclear power plants will reach at least 78 million kilowatts by 2020, accounting for about 5% of the total installed capacity. Considering the 29 million kilowatts of new nuclear projects during the 12th Five-Year Plan period, 39 million kilowatts will be added during the “Thirteenth Five-Year Plan” period. Increasing nuclear power goal planning is a very stable development goal.

Orient Securities Research believes that with the continuous implementation of nuclear power safety standards, the recovery nuclear power project reconstruction and approval have begun to have a basis and standards, and security has a higher level of protection. The nuclear power industry boomed, and it is expected that there will be new project approvals next year. The approval peak will usher in 2014. It is noteworthy that due to nuclear safety becoming the focus, the three generations of technology represented by AP1000 will be the development of China’s nuclear power equipment construction in the future. direction. This is because its safety and efficiency are higher than those of previous generations, and the technology of the CAP1400 unit in China's nuclear power equipment export program originates from the AP1000. At present, China's development route for nuclear power will also be based on the premise of ensuring safety, with the development of third-generation nuclear power technology.

It is understood that currently there are two AP1000 projects in Shandong Haiyang and Sanmen in Zhejiang, which are expected to be completed before and after 2014 and achieve power generation. As the third-generation technology is the first attempt in China and the world, the intensive approval of follow-up projects will be completed and the stable operation of these two projects will continue for some time.

He Quan, chairman of China Guangdong Nuclear Power, once disclosed to the media at an industry conference: “At present, the safety inspections and assessments of the nuclear power units under construction throughout the country have come to an end. Safety inspection reports are being formed; the “nuclear safety plan” and “ The two plans for the mid- and long-term development plan of nuclear power are advancing and are expected to be completed by the end of the year."
