METHOD FOR MANUFACTURING MAGNESIUM FLUORIDE SINTERED COMPACT METHOD FOR MANUFACTURING NEUTRON MODERATOR AND NEUTRON MODERATOR
균열 또는 절결을 억제하여 상대 밀도를 높인 불화 마그네슘 소결체의 제조 방법, 중성자 모더레이터의 제조 방법 및 중성자 모더레이터를 제공한다. 불화 마그네슘 소결체의 제조 방법은, 불화 마그네슘 분말재를 금형에 태핑 충전을 행하는 분체 충전 공정 S1과, 충전된 불화 마그네슘 분말재를, 펄스를 통전하면서 소결하는 펄스 통전 소결을 행하여, 불화 마그네슘 소결체(중간체)를 얻는 중간체 소결(펄스 통전 소결) 공정 S2를 포함한다.
The present invention provides a neutron moderator that moderates neutrons, the neutron moderator comprising: a first intermediate layered body in which a plurality of disc-shaped magnesium fluoride sintered compacts are layered; and a second intermediate layered body in which the disc-shaped magnesium fluoride sintered compacts are layered, the second intermediate layered body being layered on the first intermediate layered body and including: a hole in the disc-shaped magnesium fluoride sintered compacts; a tapered surface surrounding the hole; a bottom surface; and a vertical inner wall disposed in a disc-shaped magnesium fluoride sintered compact disposed in a bottom of the second intermediate layered body , the vertical inner wall extending in a vertical direction through the tapered surface and the bottom surface of the disc-shaped magnesium fluoride sintered compact. The top surface 2A of the first intermediate layered body 2 and the bottom surface 3B of the second intermediate layered body 3 are joined together at the neutron moderator assembling process. The top surface 3A of the second intermediate layered body 3 becomes the top surface 1A of the neutron moderator. In addition, the bottom surface 2B of the first intermediate layered body 2 and the top surface 4A of the third intermediate layered body 4 are joined together. The bottom surface 4B of the third intermediate layered body 4 becomes the bottom surface 1B of the neutron moderator. The neutron moderator 1 is manufactured by layering the first intermediate layered body 2, the second intermediate layered body 3, and the third intermediate layered body 4.
