    • 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.

    • 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

    • PROBLEM TO BE SOLVED: To provide a conveyance method of radioactive structure member with which the time required for nuclear decommissioning can be reduced.SOLUTION: A dosage rate and a temperature of a plant structure member to be carried out are measured inside a reactor building 73 in which nuclear decommissioning is to be performed, and the plant structure member is then accommodated in an accommodation container. The accommodation container accommodating the plant structure member therein carried from the reactor building 73 and decontaminated in a decontamination chamber 58 is moved on a carrier truck along with a traveling rail 44A. On the basis of a dosage rate measurement, a temperature measurement and an identification number added to the accommodation container, a control device 64A determines a decontamination building 60, a high dosage rate structure member preservation building 61 or a fuel preservation building 62 that is a conveyance destination of the accommodation container. If the conveyance destination of the accommodation container is the decontamination building 60, the control device 64A turns at 90° a turn table located at an intersection of a traveling rail 46 communicated to the decontamination building 60 and the traveling rail 44A. Thus, the carrier truck with the accommodation container placed thereon reaches the decontamination building 60.
