| Flooding is a huge concern to Nuclear Power Plants (NPPs) as experienced by the recent Fukushima Daiichi NPP failure. To improve probabilistic risk modeling of these circumstances, water rise, spray, and wave impact testing capabilities are being developed for the Component Flooding Evaluation Laboratory (CFEL) at Idaho State University.
This study concentrates on improving the previous design and analysis of a Wave Impact Simulation Device (WISD) by numerically generating steady waves and investigating further designs with different inlet angles and water depths. An experimental study is also conducted to analyze the influence of air pressure and behavior of water under these circumstances.
Steady-state and near vertical waves are successfully generated using kinematic theories via numerical and physical experimentations. The U-tube design with 45 degrees inlet and one-foot water depth produced the best results, and the concept of using air pressure as a motive force is deemed feasible through physical experiment.
