RADIOACTIVE MATERIAL STORAGE CONTAINER, AND MANUFACTURING METHOD THEREFOR

摘要

PPROBLEM TO BE SOLVED: To maintain a shielding function over a long period, while flattening a temperature when curing an area filled with a shielding member. PSOLUTION: This radioactive material storage container includes an inner cylinder 13 for storing a radioactive material, an outer cylinder 15 provided in an outer circumference of the inner cylinder 13 via a heat transfer fin 14, a shielding member storage part 16 extended along an axial direction of the outer cylinder 15 while surrounded at least by the inner cylinder 13, the outer cylinder 15 and the heat transfer fin 14, and a shielding member R filled and stored in the shielding member storage part 16 to shield a radiation, and a heat conduction member 17 is provided inside the shielding member storage part 16 separatedly from all of the inner cylinder 13, the outer cylinder 15 and the heat transfer fin 14.
