Volume 8: Seismic Engineering.
Seismic tests were carried out to confirm the operability limit acceleration for a standard motor-operated butterfly valve actuator in three excitation directions. Based on the results, seismic brackets that can operate valves even in three direction

Volume 8: Seismic Engineering.
The functional requirements of Main Steam Safety Relief Valves (SRVs) provided in Boiling Water Reactor (BWR) nuclear power plants in Japan have been previously evaluated via seismic tests and so forth; however, since the response acceleration has in

Volume 4: Fluid-Structure Interaction.
The vibration response of a typical globe valve was measured to determine the characteristics of flow-induced vibration in a cavitating flow, varying valve opening rate from 20% to 40%, and flow rate from 0.2 m3 /min to 1.4 m3 /min or maximum flow ra

Residual Stress, Fracture, and Stress Corrosion Cracking.
Through inspections of Japanese boiling water reactors (BWRs) from 2002, a high occurrence rate of Inter Granular Stress Corrosion Cracking (IGSCC) was confirmed in core shrouds and re-circulation (PLR) pipings made of low-carbon (L-grade) stainless
