maintenance management piping support reactor at R&D stage sodium cooled reactor
One of important mission of nuclear power plants (NPP) at R&D stage is to develop maintenance program for commercial reactors step by step securing safety. Basic principles of maintenance management for NPP at R&D stage were proposed. In this paper, applications for maintenance program on piping support of prototype sodium cooled fast breeder reactor Monju are studied on the basis of the proposed basic principles of maintenance management for NPP at R&D stage. ...

maintenance management preventive maintenance reactor at R&D stage
A maintenance management suitable to nuclear power plants (NPP) at R&D stage was discussed. Objectives of maintenance management of NPP at R&D stage were first clarified. Next, applicability of codes for maintenance management of commercial NPP to NPP at R&D stage was discussed. Then, requirements and consideration for maintenance management of NPP at R&D stage was proposed. In this paper, maintenance program for sodium valves are investigated. ...

Constant incident angle Guided waves NAUT Pipes Propagation Square burst wave
We have developed the constant incident angle method to inspect pipes by using high power square burst wave in non contact air upled ultrasonic testing (NAUT). We also succeeded to scan the effective guided wave propagat ed circumferentially in pipes. This per describes the optimum frequency, incident angle, the selection of prob es and examples of detecting image pictures with the onstant incident angle focusing method using focus probe....
