The relevant person in charge of our hospital went to Sweden and Germany to investigate the geological storage of spent fuel and the technology of lead bismuth fast reactor.

Vice President Woodman, Director of Advanced Energy Institute Sheng Xuan Yu and head of Sweden were interviewed by local reporters.

Invited by the Swedish Royal Institute of Technology (KTH) and the German Karlsruhe Institute of Technology (KIT), Professor Wood Min, Vice President of Tianjin High-end Equipment Research Institute of Tsinghua University, and Professor Sheng Xuan Yu, President of Advanced Energy Equipment Technology Research Institute, went to Sweden and Germany from October 30 to November 8, and visited the Swedish Royal Institute of Technology, Swedish Nuclear Fuel and Waste Management Company (SKB) and the German Karlsruhe Institute of Technology respectively, in-depth exchanges and discussions were conducted on spent fuel geological storage, medium and low-level radioactive waste storage and lead-bismuth fast reactor technology, and a preliminary consensus was reached with Sweden on technical and project cooperation.

Woodman and Sheng Xuan Yu met with Professor Ramon Wyss, Vice President, and Professor Waclaw Gudowski, a famous reactor physicist, at the Royal Institute of Technology in Sweden. During their visit to Oscar Port, they had discussions with Professor Waclaw Gudowski and the head of NOVA in Oscar Port. Woodman said that in order to meet the demand for clean energy, China plans to build a large number of new nuclear reactors in the next few decades, which provides opportunities for Chinese and Swedish scientists and entrepreneurs to cooperate in the field of nuclear power. Professor Waclaw Gudowski introduced that nuclear reactors are being built worldwide. In 2030, the world plans to build 200 new reactors. By 2050, the world plans to build 800 reactors, which is twice the total number of nuclear power plants in service in the world. Professor Waclaw Gudowski has initiated a partnership focused on the transition of spent fuel storage technology from research to market. The head of Oskar Port NOVA said that the cooperation between KTH and Chinese universities and research institutions provides a good platform for exchanges. The nuclear industry companies and subcontractors in the Port of Oscar are highly skilled and competitive, but the demand for these technologies in Sweden is decreasing, especially after the decommissioning of the four reactors at the Port of Oscar nuclear power plant. They are looking for new markets, and China is a market with great potential. They are very interested in further exchanges and cooperation with Chinese research institutions. Woodman said that the Tianjin High-end Equipment Research Institute of Tsinghua University is a professional expatriate research institute of Tsinghua University, which can provide technical services and support for enterprises in various fields. In the field of spent fuel storage, China can learn from the many high-tech solutions already developed in Sweden. Many advanced technologies from Sweden can be introduced to China and commercialized in China. Professor Waclaw Gudowski specifically mentioned that Sweden's experience can be used for reference by China. China can take inspiration from the Swedish model to dispose of spent nuclear fuel in a safe manner. In CLAB, Sweden, nuclear waste from all Swedish nuclear reactors is finally disposed of after temporary storage. But in China, spent fuel can only be placed in temporary storage tanks attached to nuclear power plants and cannot be disposed. Sheng Xuan Yu said that as China is now facing a state where spent fuel is about to reach nowhere to be resettled, it will learn from Sweden's advanced technology and promote the establishment of local spent fuel storage facilities similar to CLAB as soon as possible.

Vice President Woodman and Professor Sheng Xuan Yu visited Sweden's spent fuel geological storage facility.

During the visit, Woodman and his delegation visited the Swedish nuclear fuel facility and related laboratories in Port Oscar. The two sides discussed the follow-up cooperation and laid a good foundation for further cooperation in the future.
