More details on the Sino-Russian nuclear power bill surfaced. An announcement released on the evening of June 10 by China Nuclear Power disclosed that according to the two signed framework contracts, China and Russia will cooperate to build Units 7 and 8 in Tianwan and Xu Da Fort 3 and 4 units, using Russia-designed VVER-1200/V491 reactor units, are intended to be equipped with domestic steam turbine generator sets, and the reference power station (nuclear island) is the Leningrad NPP Phase II (phase 2 Unit 1 has been Completed and put into operation in March of this year.) The total price of the two framework contracts is 3.62 billion U.S. dollars.
On June 8, Chinese President Xi Jinping and Russian President Vladimir Putin witnessed the Sino-Russian enterprises signed the “Framework Contracts for Units 7 and 8 of Tianwan Nuclear Power Station” and the “Xudabao Nuclear Power Station Frame Contract” at the Great Hall of the People in Beijing. According to the announcement, the suppliers of the two framework contracts are the Joint Stock Company Atomstroyexport (ASE).
ASE is a subsidiary of Russia's ROSATOM and is responsible for the execution of foreign nuclear power plant construction contracts under the framework of an intergovernmental agreement. ASE is very familiar with the Chinese market. Since entering the Chinese market in 1997, ASE has cooperated with China. The Tianwan Nuclear Power Station No. 1, No. 2 and No. 3 unit were built, and the Tianwan Nuclear Power Plant No. 4 unit jointly constructed by the two parties has also completed the hot test.
If the cooperation advances smoothly, after the completion of Units 7, 8, the number of units using the Russian technology at the Tianwan Nuclear Power Station will reach 6. The Tianwan Nuclear Power Station is located in the northeast of Lianyungang City, Jiangsu Province, and is adjacent to the Yellow Sea to the east. Phase I, No. 1 and No. 2 The second stage projects 3 and 4 both use Russia's AES-91 nuclear power unit, and the third stage projects 5 and 6 unit use China Nuclear Group's M310+ improved aircraft. Among them, Tianwan Phase 2 project started construction on December 27, 2012. After the nuclear accident in Fukushima, Japan, the country was the first project to be allowed to start after the restart of nuclear power construction. The third phase of the project started construction on December 27, 2015 and became the country’s second generation plus nuclear power plant construction.
Tianwan Nuclear Power Station China Nuclear Construction Official Website
According to China National Nuclear Corporation, the Tianwan Unit 2's 2017 World Association of Nuclear Operators (WANO) composite index is 100 points, ranking first in the world's VVER nuclear power unit.
The VVER-1200 mentioned in the framework contract was developed on the basis of the practice of AES-91 and AES-92. It is currently the main model of Russian nuclear power export.
Xu Dabao Nuclear Power Plant is located in Huludao City, Liaoning Province, and is the second nuclear power project after the Hongyan River nuclear power project in Northeast China. The Xu Dabao Nuclear Power Plant is planned for 6 million kilowatt units, and the first phase of the project is planned to build two AP1000 pressures. Water reactor nuclear power unit. At present, the project has not yet started.
According to the announcement, the division of labor between China and Russia in the above four units is roughly as follows: Russia is responsible for the design of nuclear islands and the supply of nuclear island main equipment, and China is responsible for the design and equipment of conventional islands and BOP (Balance Of Plant). Goods, and also responsible for the construction of the power station, commissioning, etc. Specifically:
Russia undertakes overall technical responsibility for the design of the power station, takes charge of nuclear island design, participates in the design of instrumentation, electrical, firefighting, and communication systems, and is responsible for reactor pressure vessels, steam generators, main circulation pipelines, main pumps, and core melts. 14 nuclear island host equipment such as a catcher, and some nuclear island auxiliary equipment; technical specifications for Russian-designed nuclear island equipment and nuclear fuel for first furnace designed by the Chinese side; equipment procurement implemented by China, Jian’an , Companion service is provided during the commissioning process. The Chinese is responsible for the general plane planning of the power station, conventional islands and BOP design, division of labor according to the contract between the two parties, phased lead or participation in the instrumentation, joint design of electrical, firefighting, communications and other systems, responsible for the rest of the nuclear island equipment And all conventional islands and BOP equipment supply, responsible for the construction of the power station, commissioning and other work.
According to the announcement, after the framework contract took effect, if a certain amount of start-up money is to be paid, ASE will start the preliminary work related to the design and equipment procurement. The specific implementation of the project needs to be executed after the signing of the contract (technical design contract, total contract ) Implementation under the framework. The two parties will continue to carry out the execution contract negotiations. They plan to sign the technical design contracts for Tianwan units Nos. 7, 8 and Xu Dabao No. 3 and 4 respectively in October 2018 and March 2019, January 2019. Signed the general contract for Tianwan units Nos. 7 and 8 and Xu Dabao No. 3 and 4 respectively in June 2019. In addition, according to the “Government of the People’s Republic of China and the Government of the Russian Federation regarding the cooperation in the construction of the Xu Dabao nuclear power plant The two parties agreed in the “Xu Dabao Nuclear Power Plant Framework Contract” that the construction of the follow-up unit of the Xu Dabao Nuclear Power Plant will be studied within the framework of China's national procedural regulations.
