Residual stress improvement technologies have been developed and applied to Boiling Water Reactor (BWR) plant components in order to prevent from stress corrosion cracking (SCC) of stainless steel and Ni-based alloy materials. Water Jet Peening (WJP) is one of the effective procedures for residual stress improvement, and has the various advantages for the application to the reactor internal components of the operating nuclear power plants because WJP uses only water for residual stress improvement. As...

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 ...
