<P>PROBLEM TO BE SOLVED: To provide a radioactive material shielding structure and a radioactive material storage facility capable of maintaining high shielding performance of radioactive material while ensuring cooling performance of the radioactive material. <P>SOLUTION: A radioactive material shielding structure 2 includes: a first blade unit 41 having a plurality of first wing plates 51 disposed at a distance from each other extending in a direction (A-direction) perpendicular to an axial line with respect to air flowing from the upstream side to the downstream side of a duct communicating in an axial line direction (X-direction); and a second blade unit 42 having a plurality of second wing plates 61 disposed at a distance from each other, which is disposed at the downstream side of the first blade unit 41 at a distance therefrom, extending in a direction (B-direction) opposite to the direction with respect from the upstream side to the downstream side. Each of the first wing plates 51 and the second wing plates 61 has a front end portion 52, 62 formed at the upstream side along the axial line with respect from the upstream side to the downstream side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
