Boiling Water Reactor Flow-Induced Acoustic Resonance Safety Relief Valve Steam Dryer
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 ...

non-contact measurement pipe insulation Pipe-wall thinning inspection ultrasonic measurement
A pipe-wall thinning measurement is one of key inspections to ensure the integrity of the piping system in power plants. Since the pipes of the power plants are covered with insulation, the removal of the insulation, which is time-consuming process in general, is required for the pipe-wall thinning inspection. We have been developing an innovative measurement technology, which enable the pipe-wall thinning inspection without removing the insulation, based on the non-contact ultrasonic sensor proposed by ...
