Chinese Academy of Sciences, the official website of the Chinese Academy of Sciences news recently, the Chinese Academy of Sciences deputy party secretary and vice president Liu Weiping, vice president, party members Xiangribin, President of Shanghai University of Science and Technology, thorium-based molten salt reactor nuclear energy system (TMSR) strategic pilot science and technology chief scientist Jiang Mianheng and his entourage went to Gansu for investigation and study, and signed a strategic cooperation framework agreement with Tanshun People's Government of Gansu Province.
The Thorium-based Molten Salt Reactor Nuclear Energy System (TMSR) is one of the six candidates for the fourth generation of advanced nuclear energy systems, including thorium-based nuclear fuel, molten salt reactor, three subsystems for comprehensive utilization of nuclear energy, High inherent safety, less nuclear waste, non-proliferation performance and economy better.
Among them, molten salt reactor uses high-temperature molten salt as a coolant, with high temperature, low pressure, high chemical stability, high heat capacity and other thermal properties, without the use of heavy and expensive pressure vessel, suitable for compact, lightweight and low cost Small Modular Reactor In addition, the molten salt reactor uses waterless cooling technology, which can operate with a small amount of water and can generate electricity efficiently in arid areas. The high temperature nuclear heat output from the molten salt reactor can be used for power generation and industrial thermal applications , High temperature hydrogen production and hydrogen absorption of carbon dioxide methanol.
Prospects for comprehensive utilization of nuclear energy based on TMSR. Chinese Academy of Sciences
According to a report by the Chinese Academy of Sciences, Jiang Mianheng said in a panel discussion on the same day that the utilization of nuclear energy for the development of thorium resources has been the dream of more than half a century since the beginning of the year. The Chinese Academy of Sciences has systematically mastered thorium Through the strategic cooperation between the two parties, it is bound to bear fruit in Gansu. TMSR has the characteristics of safety, cleanness, water-free and high temperature. After the completion of TMSR experimental reactor in 2020, Gansu will gradually become the guarantee of ' Belt and Road "strategy for the country's new energy base.
According to the information from China Wuwei Network, in April this year, Wuwei City, Gansu Province and Chinese Academy of Sciences signed a strategic cooperation framework agreement for building a thorium-based molten salt reactor nuclear power system (TMSR) project in Hongshagang, Minqin County. Construction, with a total investment of 22 billion yuan.
Liu Weiping said that Gansu Province is a nuclear energy industry and a big province for clean energy. The TMSR project fits well with Gansu Province's energy-intensive strategy. Not only its characteristics are in line with the natural environmental conditions here, but the key raw materials such as thorium and salt are all here Good foundation.
He emphasized that the TMSR project not only can drive downstream industries such as raw materials and equipment manufacturing, but also closely integrates with wind power, optoelectronics industry and coal chemical industry through molten salt heat storage and high-temperature hydrogen production to realize green industry development from the supply side Liu Weiping hopes both sides will cooperate closely and strengthen the docking, while ensuring the construction and landing of the TMSR project and planning the downstream and related industries well in advance.
Gansu Provincial Committee, Governor Tang Ren Chinese Academy of Sciences decided to build Thank TMSR project ground Gansu. He said, TMSR project and Gansu Province, resources, environment, industry structure and other aspects of the condition is very fit, gathered in climate, geography and people, here will be able to take root, grow and develop. Tang Renjian asked the departments not only to fully support and protect the landing TMSR and construction projects, but also to ponder the possible difficulties ahead, advance planning solutions.
According to the Chinese Academy of Sciences, Molten Salt Heap R & D started in the United States in the late 1940s. The Oak Ridge National Laboratory was established in 1965 as the Liquid Molten Salt Experimental Reactor (MSRE), which is the only one built and operated in the world Liquid fuel reactors and the only reactors to successfully operate thorium-based nuclear fuel (uranium-233), but because of the cold war's consideration, the focus on civilian use of molten salt heaps has been halted and the research and development of molten salt heaps in the United States ceased. From the early 1970s onwards, China also selected the thorium-based molten salt reactor as a starting point for the development of civilian nuclear energy. Shanghai's '728 Project' built a zero-power cold-state molten salt reactor in 1971 and reached the threshold, but was limited to the technological, industrial and economic levels at that time, 728 Project 'to build a light water reactor.
China restarted its study of thorium-based molten salt heaps in 2011. In 2011, focusing on the needs of national energy security and sustainable development, the Chinese Academy of Sciences (CAS) deployed and launched the first advanced nuclear fission energy-thorium of the strategic pilot science and technology project of the Chinese Academy of Sciences (category A) Based on 20 years' plan, TMRR will be the first in the world to realize the application of thorium-based molten salt reactor and establish the industrial chain of thorium-based molten salt reactor and the corresponding scientific and technological team. Shanghai Institute of Applied Physics, Shanghai Institute of Organic Research, Shanghai Institute of High-tech, Changchun Institute should be, the Institute of Metals and other 10 units involved in research institutions.
