Attachment jig and attachment method for attaching a mounting member to the surface of a radioactive substance storage container, and a radioactive substance storage container unit including a radioactive substance storage container, a mounting member and a mounting jig

摘要

PROBLEM TO BE SOLVED: To suppress degradation in a fixing jig due to temperatures or radiation without the need of forming a bolt hole in a surface of a radioactive material storage container or conducting welding on the surface, and enable an attachment target member to be held on a surface of the radioactive material storage container over a long time.SOLUTION: A fixing jig 50 includes: a magnet 51 fixed with a magnetic force to a part made of a magnetic material of a side surface 12a of a radioactive material storage container; a space formation member 52 having a recess part 52x as a holding space for holding a temperature sensor (attachment target member) 100; and a bolt 53 for pressing the space formation member 52 toward the side surface 12a.SELECTED DRAWING: Figure 2
