JIG AND METHOD FOR FIXING ATTACHMENT TARGET MEMBER ON SURFACE OF RADIOACTIVE MATERIAL STORAGE CONTAINER, AND RADIOACTIVE MATERIAL STORAGE CONTAINER UNIT CONTAINING RADIOACTIVE MATERIAL STORAGE CONTAINER, ATTACHMENT TARGET MEMBER, AND FIXING 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
