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： PURPOSE:To increase the corrosion resistance and to prevent a radiating damage, by composing the component member of a fuel assembly with a Zr radical alloy, and making the Zr radical alloy in an ultra-minute crystal grain size including Fe. CONSTITUTION:A fuel cladding pipe to cover a uranium pellet for fuel of a fuel is held by a spacer, and plural cladding pipes are housed in a channel box. At least one of these component members is composed of a Zr radical alloy, and its mean crystal grain size is made less than 1000nm, favorably making into an ultra-minute crystal with 10 to 100nm. As a result, a radiation defect by a neutron radiation is not generated in the crystal grains, so as to improve the neutron damage resisting property. And by fixing and solving a corrosion resistance improving element such as Fe in a Zr matrix, the corrosion resistance is improved. In this case, a high effect can be obtained by making the including ratio 0.5 to 30wt.%, being more favorable to be 1 to 5wt.%. By using a material in the ultra-minute crystal condition in which an alloy additive element is fixed and solved in the Zr in such a way, the component member of the fuel assembly can be obtained by applying a process and a heat treatment.

摘要： PURPOSE: To easily control the irradiation position and irradiation quantity of an ion beam by coating the reflective surface of a periscope with a fluores cent material and observing an ion beam image and a target image in the same direction at the same time.
CONSTITUTION: The reflective surface 3 of the periscope 1 is coated with the fluorescent material. This is for not only irradiating the reflective surface 3 with the ion beam 6 and making light 7 from a target 2 incident on an incidence surface 4 so as to monitoring the profile of the ion beam, but also observing the target at the same time. The periscope 1 is arranged in a vacuum tank 10 so that the reflective surface 3 is irradiated with the ion beam 6 at about 45°. Thus, the ion beam image and target images are observed simultaneously on an ocular surface 5 outside the vacuum tank 10. Further, the target 5 itself has no light emitting ability, so it is lighted by a target lighting lamp 9.

摘要： PURPOSE:To decrease a peak width possible for retrieval and to reduce a search time by inputting the digital measuring value of a supervised amount to an address setting device, and storing the digital measuring value of a manipulated value in a memory designated by a definite address value. CONSTITUTION:The manipulated variable is changed X by X by a manipulated variable change device 2 to a system 1 of control object. The manipulated value and the supervised value are measured by measuring devices 3, 4, and they are converted into digital values by an A/D converter 5. The digital value of the supervised amount is inputted to an address setting device 7 to obtain an address value corresponding to the quantity of the supervised amount. The digital value of the manipulated value is stored in a storage location of a memory 6 having the said address as the address number. After data sampling and storage are finished, the peak value is retrieved by a comparator 8. Thus, the peak width is reduced and the retrieval time is decreased.

摘要： PURPOSE: To enable welding of stainless steel containing He by performing a flaw introduction and heat input on the stainless steel before welding, thereby holding He in the grains, suppressing the inflow into the grain boundary and preventing intercrystalline cracks due to the formation of He bubbles. CONSTITUTION: In the step 101, a flaw introduction is performed by using one or more means from a heat cycle, mechanical stress induction, mechanical impact addition and ion irradiation. In the step 102, a heat input before welding is performed by using one or more means from RF heating, laser irradiation and electric heating. In the step 103, welding is performed after He is held in the grains by the flaw introduction and the heat input before welding. Thus, the welding of the stainless steel containing He is performed without causing intercrystalline cracks, thereby reducing the repair cost of the components of a nuclear reactor as well as the repair period.
