摘要： PROBLEM TO BE SOLVED: To provide a structure for leading-in/out a work robot between a storage pit which stores glassified bodies which is a high-level radioactive waste and a passage. SOLUTION: A leading-in/out chamber 10 is demarcated in the bottom section of a passage 8 through an opening/closing lid 12 and, at the same time, a commnunicative hole 15 is formed through a shielding wall 7 which separates the chamber 10 from a storage pit 2 and a transfer member 16 which clogs the hole 15 and delivers and receives a work robot 23 is slidably provided in the hole 15. Therefore, the leading-in/out work of the robot between the storage pit 2 and the passage 8 can be conducted safely, because leaking-out radiation can be prevented effectively.

摘要： PROBLEM TO BE SOLVED: To efficiently remove nuclear decay heat, to improve shock resistance and aseismatic property and to improve a handling property by filling molten glass in a sealed container in the closely stuck to heat transfer structural bodies, and transferring heat between a center section and a container wall via the structural bodies. SOLUTION: Heat transfer structural bodies 2 are loaded in a container main body 11, then a container upper section 12 is mounted on the barrel section opening 11a of the main body 11, and a weld section W is formed to seal the junction between the main bodies 11 and the upper section 12. Molten glass is poured from a filling port 13 and is filled in the main body 11. The molten glass is filled in the space between the structural body 2 and a container wall 11b, and it is kept at the closely stuck state to the vertical heat transfer lines 21, lateral heat transfer lines 22 and ring-like connecting lines 23. The decay heat of the radioactive element contained in a glass layer is transferred to the wall 11b via the glass layer and the structural bodies 2 and is removed by the container 1 and the air around it. Multiple stages of the structural bodies 2 are arranged in the height direction of the main body 11, and they transfer the heat of the glass layer to the wall 11b to accelerate cooling.
