摘要： PROBLEM TO BE SOLVED: To provide the superior corrosion resistance even under a corrosive environment though the different kinds of metals are bonded, by exposing a bolt part made of stainless steel superior in corrosion resistance, on the ground which is the corrosive environment and needs the corrosion resistance. SOLUTION: A bolt member exposed to the ground 8 for fixing a mechanical structural body, is made of SUS 304 superior in corrosion resistance, which does not cause the problem on corrision. In a case when the water intrudes insides of the concrete 7 from a boundary part of the concrete 7 and a bolt member 3, the galvanic corrision is inhibited on a rod member 2 and the bolt member 3 by the action of an applied zinc-contained butylene rubber sheet 5, and the cathode corrision control is applied to a heat-affected zone of the bolt member 3. Accordingly the anchor bolt is not damaged by the corrision even when it is used under the corrosive environment, and the fastening of the mechanical structural body of high reliability can be realized for a long period.

摘要： PROBLEM TO BE SOLVED: To accurately conduct the integrity evaluation and remaining life evaluation of a plant structure by evaluating the potentiality of degradation progression of core equipment material from design data, material data and operation data. SOLUTION: A composite diagnostic system of the core structure includes a primary diagnostic device 1 evaluating the degradation potentiality of each core equipment and selecting the components and parts requiring minute inspection, a secondary diagnostic device 2 predicting remaining life including the progression of degradation of core equipments and a tertiary diagnostic device diagnosing the degradation of the core equipments non-destructively or prior- destructively to the diagnostic object equipments and parts. The devices 1 and 2 are systems including software capable of loading in a work station, etc. These series of data are preserved in the data base of the diagnostic component selection system. In the first periodical inspection when the degradation status of the core structure is diagnosed and what kind of problem is generated at which point can not be known, the damage state of the equipments can be predicted with the primary and the secondary diagnostic devices.

摘要： PROBLEM TO BE SOLVED: To prevent a fretting fatigue failure by providing a difference in level on the mounting welding part of a nozzle so as to have a diameter larger than the nozzle tip, and connecting this diameter increased part of the nozzle to a stub provided on a piping by welding. SOLUTION: A nozzle 13 has a difference in level to increase the diameter on the base side. The inside diameter of a stub 12 is increased according to tit, and the nozzle 13 is inserted thereto and connected in a mounting welding part 15'. When the upper end of the stub 12 is conformed to the corner part of the difference in level part of the nozzle 13 followed by welding, fretting fatigue is not caused since the outer surface of the nozzle 13 does not contact the inner surface of the stub 12 or the welding metal. Only the stress collection resulted from the reverse corrugated form of the welding part 15' can be considered. Thus, the failure by fretting fatigue resulted from the flowing vibration of the nozzle 13 can be prevented.

摘要： PROBLEM TO BE SOLVED: To improve the reliability to the strength of a joined part by heating the joining part at high temp. and forming an oxide film on the surface of a zirconium or zirconium alloy-made tube and on the surfaces of an outer sleeve and an inner sleeve in a tubular member. SOLUTION: The zirconium-niobium alloy tube 1 is closely joined by mechanically combining in the sandwiching condition with the stainless steel-made outer sleeve 2 and inner sleeve 3. After connecting by expanding the tube and the sleeves, a heating jig 8 having a heater 7 is inserted into the inner surface side of the inner sleeve 3, and the tube and the sleeves are heated at the high temp. in the atmosphere, and the high temp. oxide film is formed to each surface of the zirconium-niobium alloy tube 1 and the outer sleeve 2 and the inner sleeve 3 made of the stainless steel. Thereafter, an extending tube made of the same quality of stainless steel is joined by welding to the end part of the inner sleeve 3 as the same way as the conditional way.
