摘要： PROBLEM TO BE SOLVED: To provide a residual stress evaluation method capable of nondestructively evaluating residual stress on a waterjet peening processed surface in a reactor.
SOLUTION: Peening traces are sampled from an image photographed the waterjet peening processed surface. The whole area or the number of peening traces per unit area is measured. Then, the residual stress is evaluated by substituting it into a relational expression between the residual stress and the whole area or the number of peening traces, prepared in advance. Or, a surface area increasing rate after and before peening work is calculated, and the residual stress is evaluated by substituting it into a relational expression between the residual stress and surface area increasing rate, prepared in advance. Thus, the residual stress on the peening processed surface is nondestructively evaluated under internal circumstances in the nuclear reactor.

摘要： PROBLEM TO BE SOLVED: To improve a residual stress in a pipe inner surface by generating collapse of grown cavitation foam in the pipe inner surface when applying water jet peening to the pipe inner surface.
SOLUTION: The method is carried out by holding a pipe having openings at both ends with a holding device, blocking one end of the pipe, inserting an ejection nozzle from the other pipe end, and ejecting a liquid supplied to the ejection nozzle into the pipe inside from the ejection nozzle at an inclination of 9° or less with respect to an axis center of the pipe, to thereby generate back-flow of the liquid ejected from the ejection nozzle, in the pipe inside. Thus, the residual stress in the pipe inner surface is improved by impact pressure caused by collapse of the cavitation foam accompanying the liquid. A collision distance from a nozzle ejection hole to the pipe inner surface is set to a value equal to a distance of growth of the cavitation, and the grown cavitation is collided against the pipe inner surface. As a result, the impact pressure generated at the collapsing of the cavitation can be applied to the pipe inner surface, and therefore the residual stress in the pipe inner surface can be improved.

摘要翻译：要解决的问题：通过在管内表面上施加水喷射喷丸时，通过在管内表面中产生塌陷而改善管内表面中的残余应力。解决方案：该方法通过用保持装置在两端保持具有开口的管道进行，阻塞管的一端，从另一管端插入喷嘴，并喷射供应到喷嘴的液体相对于管的轴心以9°以下的倾斜从喷嘴喷入到管内，从而在管内部产生从喷嘴喷出的液体的回流。因此，通过伴随液体的气蚀泡沫的崩溃引起的冲击压力，管内表面中的残余应力得到改善。从喷嘴喷射孔到管内表面的碰撞距离被设定为等于空化生长距离的值，并且生长的气蚀与管内表面相撞。结果，可以在管内表面上施加在空化崩溃时产生的冲击压力，因此能够提高管内表面的残留应力。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To shorten WJP (Water Jet Peening) work time by minimizing the scanning distance of an injection nozzle when a workpiece to be subjected to WJP is thoroughly worked.SOLUTION: The nozzle is moved to a starting position (S15), and a high-pressure pump 5 is started. Optimum supply pressure and standoff are searched and set (S16 to S25). When the nozzle scans in an X shaft direction, distribution of shock wave generating positions and WJP width are calculated (S32), and scanning pitch in an axial direction is set (S36). When the nozzle reaches an end position in the X shaft direction, scanning is stopped, and the nozzle is scanned in a Y shaft direction by the scanning pitch set in S36 (S38). Such rectangular scanning in the X and Y shaft directions is repeated (S31 to S39). When the nozzle reaches a scanning end position, the high-pressure pump is stopped (S40), and work is terminated.

摘要： PROBLEM TO BE SOLVED: To provide a water jet peening method in which the resonance of structures in a reactor pressure vessel other than objects to be subjected to water jet peening are avoidable.SOLUTION: A jet 8 containing cavitation air bubbles is injected from an injection nozzle 4, and water jet peening is performed on the inner surface of a reactor pressure vessel 1. The pressure pulsation 20 resulted from the jet 8 reaches a reactor core internal structure 2. The pressure variation due to the pressure pulsation 20 is detected with a pressure sensor 15 near the reactor core internal structure 2 to be input into an arithmetic unit 17. The arithmetic unit 17 separates the oscillatory waveform of the natural frequency fcomponent of the reactor core internal structure 2 from the pressure variation. A control device 18 controls an electromagnetic valve 12 on the basis of the oscillatory waveform, and injects water stream with the pressure pulsation 22 having the amplitude and frequency comparable in opposite phase to the oscillatory waveform from a jet orifice of an enlarged part 24. The pressure pulsation 20 is canceled with the pressure pulsation 22, turning into the pressure pulsation 23 with small amplitude.

摘要： PROBLEM TO BE SOLVED: To control the forced excitation frequency of waterjet peening.SOLUTION: Because the forced excitation frequency of waterjet peening is found out to vary depending on the injection distance, the injection flow rate, and the diameter of a nozzle, based on the natural frequency of waterjet peening construction objects the resonance can be prevented by selecting the injection distance, the injection flow rate, and the diameter of a nozzle of the waterjet peening. The forced excitation frequency of the waterjet peening is determined by fixing an injection receiving plate to a load cell a natural frequency of which is larger enough than the forced excitation frequency, by performing the waterjet peening against the injection receiving plate, and analyzing the load data detected by a load cell.
