グ。[Scope of Claim for Utility Model Registration] 1. In a thimble plug that is inserted into a control rod guide tube installed in a fuel assembly for a pressurized water reactor to adjust the flow rate, irradiated materials for producing radioactive isotopes are used. A thimble plug for producing radioactive isotopes, in which the simple plug is made of the irradiated substance when the material is equivalent to stainless steel, which is the material of the thimble plug. 2. The thimble plug for radioisotope production according to claim 1, wherein the cross section of the thimble made of the irradiation material for radioisotope production has fins extending in a radial shape. 3 In a thimble plug that is inserted into a control rod guide tube installed in a fuel assembly for a pressurized water reactor to adjust the amount of water flowing, the irradiation material for producing radioactive isotopes is made of stainless steel, which is the material of the thimble plug. If the thimble plug is different from steel, the thimble plug is provided with a hollow part, and the irradiation substance is confined in the hollow part.
