摘要： PROBLEM TO BE SOLVED: To enhance an air-tightness inside a cavity by the inner container and a double lid, as well as, to prevent radioactive materials inside the cavity from leaking.
SOLUTION: In a container for radioactive material (cask 100), the outer container 9 is placed outside an inner container 8 molded integrally by deep drawing. The outer container 9 is made of carbon steel and has gamma-ray shielding function, but the sealing performance is not required of the outer container 9. Since the inner container 8 is shaped like a bottomed container by integral molding, it can prevent radioactive materials inside it from leaking. Especially, the container has a double lid, consisting of a primary lid and a secondary lid placed on the side of an opening of the container 8, and a sealing surface and a mating surface are formed respectively on a stepped face where the secondary lid located outside the container, in comparison with the primary lid is in contact with the edge of the container.

摘要： PROBLEM TO BE SOLVED: To prevent damage to a neutron shield provided inside an outer tube of a radioactive material containment vessel.
SOLUTION: An auxiliary shield 560 is sandwiched between a buffer 550 and an outer tube 503. An impact to the buffer 550 is transmitted to the outer tube through the auxiliary shield 560, and is transmitted to the other shield 550 through the opposite auxiliary shield 560. Thereby, because the outer tube 503 does not receive a load, the neutron shields 502 thereinside are not damaged.

摘要： PROBLEM TO BE SOLVED: To effectively shield an object from neutrons and γ rays, and to provide a composition for a neutron shield which has proper workability, as well as maintains refractoriness.
SOLUTION: The composition for the neutron shield which has proper workability, as well as keeps neutron shielding capability and refractoriness, is obtained by lading the composition for the neutron shield with a powder of magnesium hydroxide whose particle diameter is 1.5 to 15 μm. Moreover, powdery carbon, contained in the composition restrains air bubbles from appearing in resin, enables more effective shielding from neutrons. In addition, by including a density increasing agent in the composition, the specific gravity is increased, which enables more effective shielding from the γ rays.
