Cryogenic In-Pool Assembly

Cryogenic Cold Neutron Source In-Pool Assembly

The Cryogenic Cold Neutron Source In-Pool Assembly is a crucial device installed near a reactor. It converts thermal neutrons generated during fission into cold neutrons. This assembly was jointly developed by the Korea Atomic Energy Research Institute (KAERI) and our company, Moojin Keeyeon Co., Ltd. It has been delivered to the research reactor operated by Delft University of Technology in the Netherlands.

Delft University of Technology in the Netherlands

This equipment was designed and installed as part of the OYSTER (Optimized Yield - for Science, Technology, and Education - of Radiation) project, which was awarded to the Korea Atomic Energy Research Institute. Due to the necessity of operating under high vacuum conditions and extreme environments of -250°C, the design and manufacturing of each component are extremely demanding.

In particular, the assembly requires ultra-high precision special aluminum alloy welding technology, which only the world's leading technol ogy holders can attempt to manufacture.

Nuclear power plant equipment is broadly divided into Main Power Generation Equipment, Balance of Plant(BOP), and Spare Parts. Large companies such as Doosan Enerbility and the U.S. firm Westinghouse manufacture Main Power Generation Equipment like reactors, turbines, generators, and steam generators, while BOPs and Spare Parts areproduced by small and medium-sized enterprises. Moojin Keeyeon Co., Ltd. primarily manufactures BOP and Spare parts, and it has notably exported six BOP packages to the UAE Barakah Nuclear Power Plant, the highest number among South Korean SMEs.
