AHYL Nuclear Energy New Material Technology Co., Ltd. and China Institute of Nuclear Physics invested in the establishment of a joint venture company. The company has advanced high-energy ball mills, cold isostatic presses, vacuum sintering furnaces, extruders, hot rolling mills, levelers, cutting machines, surface treatment production lines and other equipment, and now has the mass production capacity of neutron absorption plates.
The company relies on its partners’ R&D, inspection and testing capabilities in the nuclear field, and engages in aluminum-based boron carbide composite materials, neutron absorption plates for fuel storage grids, lead-boron polyethylene shielding materials and products, new nuclear engineering materials and products, and nuclear Development, production and sales of technical machinery, equipment and instruments.
At present, the company has produced aluminum-based boron carbide composite neutron absorption plates with a content of 5-35% boron carbide. The maximum length is 4800mm, the maximum width is 520mm, and the thickness is 0.5-15mm. Bending and welding process.
The thickness of the lead-boron polyethylene sheet produced by the company ranges from 5mm-80mm, with a lead content of 80% and a boron carbide content of 5%.
The company has strong scientific research capabilities, design, calculation and research and development capabilities in the field of nuclear materials and shielding, and conducts product design calculations, tests, and verifications for metal-based and non-metal-based shielding materials.
At present, the company's products include Haiyang 3#4# unit fuel storage grid neutron absorption board, CAP1000 project new fuel transportation container neutron absorption board, neutron absorption board for Chinese scientific research equipment…
Introduction and application of neutron absorption board
The neutron absorption board can use 6 series aluminum alloy powder and 1 series aluminum alloy powder as the base material according to the different use environment, and add a certain proportion of boron carbide powder (generally 5%-35%) according to the powder metallurgy process. Into various specifications of the board.
The neutron absorption plate is mainly used in fuel storage equipment of different reactor types, such as new fuel and spent fuel.
At present, the neutron absorption plate (with a boron carbide content of 31%) has completed reliability tests for materials such as uniformity test, radiation resistance test, thermal aging performance test, and corrosion resistance test. The results prove that the material fully meets the 60-year Service life.
