According to news from the official website of the Chinese Academy of Sciences, Liu Weiping, deputy secretary and vice dean of the Chinese Academy of Sciences, Xiang Libin, vice president and member of the Party Group, President of the Shanghai University of Science and Technology, and Chief Scientist of the Strategic Leading Science and Technology Project of TMSR Nuclear Power System (TMSR) Jiang Mianheng and his entourage went to Gansu for investigation and investigation, and signed a strategic cooperation framework agreement with the Gansu Provincial People's Government for the TMSR project.
The Thorium Molten Salt Reactor Nuclear Energy System (TMSR) is one of six candidates for the fourth-generation advanced nuclear energy system. It includes three subsystems, ie, helium-based nuclear fuel, molten salt reactors, and nuclear energy. High inherent safety, less nuclear waste, better anti-diffusion performance and economy.
Among them, the molten salt stack uses high-temperature molten salt as a coolant, and has high-temperature, low-pressure, high chemical stability, high heat capacity and other thermal properties, eliminating the need for heavy and expensive pressure vessels, and is suitable for compact, lightweight, and low-cost construction. Small modular reactor. In addition, the molten salt reactor adopts a water-free cooling technology, which requires only a small amount of water to operate and can achieve high-efficiency power generation in arid regions. The high-temperature nuclear heat output from the molten salt reactor can be used for power generation. It can also be used for industrial heat applications, high-temperature hydrogen production, and hydrogen absorption of carbon dioxide to methanol.
TMSR-based prospects for the comprehensive utilization of nuclear energy. Chinese Academy of Sciences
According to the report of the Chinese Academy of Sciences, Jiang Mianheng stated in the discussion on that day that the development of nuclear energy utilization for thorium resources is a dream of more than half a century in the world. Through the implementation of the Class A Strategic Pilot Science and Technology Special Project for more than six years, the Chinese Academy of Sciences has systematically mastered a series of key technologies of the Rudiene-based molten salt reactor. Through strategic cooperation between the two parties, it will surely bear fruit in Gansu. TMSR is characterized by safety, cleanliness, waterlessness, and high temperature. After the TMSR experimental reactor is built in 2020, Gansu will gradually become a new energy base for the implementation of the “One Belt and One Road†strategy and facing the country.
China’s Wuwei.com News shows that in April this year, Wuwei City, Gansu Province and the Chinese Academy of Sciences signed a strategic cooperation framework agreement for the construction of the Rusad-based Molten Salt Reactor Nuclear Energy System (TMSR) project in Hongshagang, Cixian County. During the period of construction, the total investment is 22 billion yuan.
Liu Weiping stated that Gansu Province is a major province of the nuclear energy industry and clean energy. The TMSR project is very much in line with the strategy of a province with a strong energy province in Gansu province. Not only does it match the natural environmental conditions here, but the key raw materials such as cesium and salt are all well-founded here.
He emphasized that in addition to promoting downstream industries such as raw materials and equipment manufacturing, the TMSR project can also be integrated with wind power, optoelectronics, and coal chemical industries through technical means such as molten salt heat storage and high temperature hydrogen production, and realize green industry development from the supply side. . Liu Weiping hopes that the two sides will closely cooperate with each other and strengthen the docking. While ensuring the landing and construction of the TMSR project, it will also do a good job in planning the downstream and related industries in advance.
Tang Renjian, deputy secretary of the Gansu Provincial Party Committee and Governor of China, thanked the Chinese Academy of Sciences for deciding to land the TMSR project in Gansu. He said that the TMSR project and Gansu Province's resources, environment, and industrial structure and other conditions are extremely consistent. When they gather together for the time, place, and people, they will surely be able to take root and grow. Tang Renjian requested all relevant departments not only to fully support and guarantee the landing and construction of the TMSR project, but also to think in advance about the difficulties that may be encountered and to plan solutions in advance.
According to the report of the Chinese Academy of Sciences, research and development of molten salt reactors began in the United States in the late 1940s. The Oakland National Laboratory built the Liquid Fuel Molten Salt Experimental Reactor (MSRE) in 1965, which is the only one built and operated in the world. The liquid fuel reactor is also the only reactor that successfully achieves the operation of the thorium-based nuclear fuel (uranium-233). However, due to the "Cold War" considerations, the civilian molten salt reactor plan was discontinued, and the development of US molten salt reactors was suspended. At the beginning of the 1970s, China had also chosen Tantalum-based molten salt reactors as a starting point for the development of civil nuclear energy. Shanghai's “728 Project†built a zero-power cold molten salt reactor in 1971 and reached criticality. However, due to the technological, industrial, and economic conditions at that time, the "728 Project" was switched to the construction of a light water reactor.
In 2011, China restarted the study of sulfhydryl-based molten salt reactors. In 2011, the Chinese Academy of Sciences focused on the needs of national energy security and sustainable development and deployed the first batch of strategic pilot technology projects (Class A) of the Chinese Academy of Sciences “Future Advanced Nuclear Fission Energy—Tanium-based Molten Salt Reactor Nuclear Energy System (TMSR)â€. In 20 years or so, the first application of sulphonium-based molten salt reactors has been realized in the world, and at the same time, a sulfhydryl-based molten salt reactor industry chain and a corresponding scientific and technological team have been established. Specially relying on the participation of research institutes from 10 institutes including the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences, the Shanghai Institute of Organic Chemistry, the Shanghai High-level Research Institute, the Changchun Yinghua Institute, and the Metal Institute.
