摘要： PROBLEM TO BE SOLVED: To provide a method for producing a test material being employed for evaluating soundness of a large scale structure, e.g. reactor pressure vessel, while taking account the fact that a steel material being used deteriorates through irradiation. SOLUTION: A steel test material comprising C: 0.23-0.25% Si: 0.35-0.45%, Mn: 1.40-1.50%, P: 0.025-0.030%, S: 0.019-0.035%, Ni: 0.40-0.50%, Cr: 0.25% or less, Mo: 0.50-0.60% and the remainder of Fe and inevitable impurities is quenched at 845-910 deg.C and then tempered at 545-575 deg.C. Since chemical composition, heat treatment conditions, metal texture, and the like, are approximate to those of actual product, evaluation test can be performed accurately.

摘要： PURPOSE:To estimate the mechanical properties of a metallic structure extremely accurately by joining metallic materials which are given similar properties by specific thickness by adjusting chemical components. CONSTITUTION:The metallic materials containing different chemical components are joined in multilayered structure to obtain the breakdown toughness test material which varies in mechanical property stepwise, and the chemical components are adjusted to obtain the breakdown toughness test material given substantially the same properties as the thickness-directional properties of a material of metallic structure such as a pressure container in operation, for example, in an update period. Metallic plates are used as metallic materials whose chemical components are adjusted and joined by a hot rolling and pressing method, an explosion bonding method, a diffusion joining method, etc.; and a welding material is used for built-up welding so that plural layers are formed, thus forming a laminate plate as the breakdown toughness test material.

摘要： PURPOSE: To improve durability of a device by sequentially opening and closing a supply valve group, a discharge valve group, and an escape valve group by applying pressure inside a pressure vessel in a cyclic form within the range from a super high state to a low state. CONSTITUTION: Super high pressure water in a collection header 8 is fed to a branch header 9 by opening a supply valve group 2 through a supply piping 16, a nozzle 5 and a supply valve. Since the blanch header 9 is directly connected to a pressure vessel 1 through a control piping 18, the super high pressure water is also fed to the pressure vessel 1. Pressure inside the pressure vessel 1 is also increased. Discharge rate from the super high pressure water pump escapes to a tank 13 through the collection header 8, an escape valve, and a nozzle 7 by closing the supply piping 16 and simultaneously with opening an escape valve group 4. On the other hand, the super high pressure water inside the pressure vessel 1 is discharged to the tank 13 through the control piping 18, the branch header 9, a discharge piping 17, a discharge valve, and the nozzle 6 by opening a discharge valve group 3.

摘要： PROBLEM TO BE SOLVED: To perform a test in safety by inserting a core into a test body, making a circulation path in the core for internally pressurizing and performing a breaking test and supplying a high temperature heating medium externally. SOLUTION: A core 2 for reducing the volume of a test body 1 is provided in the test body 1. The gap between the core 2 and the test body 1 is filled with a pressurized medium 3 being supplied by a high pressure pump 9 through a pressurization hole 11. A heating medium 7, i.e., high temperature high pressure water, is circulated through the core 2 by means of a circulation facility 10 in order to heat the pressurized medium 3 and the test body 1 through the core 2. An auxiliary heater 4 is arranged on the outside of the test body 1 in order to regulate the temperature distribution thereof more uniformly and the auxiliary heater 4 is covered with a thermally insulating material 5. When the pressurized medium 3 and the test body 1 reaches a specified temperature, the pressurized medium 3 is pressurized gradually by means of a high pressure pump 9 and a breakage is generated in the test body 1 from an initial crack 6 and then the braking pressure is determined.

摘要： PURPOSE:To obtain a manufacture method capable of producing a test material in which a measure against deterioration of steel material due to irradiation embrittlement is incorporated in evaluation of integrity of a large-sized structure such as a reactor pressure vessel. CONSTITUTION:Steel material for test material composed of C: 0.21-0.25%, Si: 0.35-0.45%, Mn: 1.10-1.65%, P: 0.020-0.030%, S: 0.025-0.035%, Ni: 0.40-0.50%, Mo: 0.40-0.65% in weight percent and the residual composed of Fe and unavoidable impurities are quenched at 845-1000 deg.C and thereafter annealed at 500-620 deg.C. The test material in which low toughness and high strength are performed and chemical composition, heat treatment conditions, metal structure and the like are approximated to a real product is obtained without irradiation of neutrons and the like.
