A feasibility study was conducted on advancement of plant maintenance technology by noticing the integration of non destructive test, fracture mechanics, distributed netw ork, and human interface technologies. In fact, the study was conducted by dividing into the two area: Area A for the methods of non destructive testing and the simulatio n methods on fracture mechanics, while area B for human interface technologies for maintenance work support. During the course of the feasibility study, the developmenta...

The BWR-3 steam dryer in the Quad Cities Unit 2 Nuclear Power Plant was damaged by high cycle fatigue due to acoustic-induced vibration under extended power up-rate conditions. The dryer failure was as attributed to flow-in duced acoustic resonance at the stub pipes of safety relief valves (SRVs) in the main steam lines (MSLs). The acoustic resonance was considered to be generated by interaction between the sound field and unstable shear layer s across the closed side branches with SRV stub pipes. We have ...
