NEUTRON MODERATOR
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.
