This report describes progress on Nuclear Power Plant component flooding fragility research conducted at the Component Flooding Evaluation Laboratory (CFEL). The progress includes additional steering committee membership and invitations, performance improvements to the Portal Evaluation Tank (PET), PET based experiments using industrial steel doors, pipe rupture spray pattern characterization, coupling the smoothed particle hydrodynamics (SPH) code Neutrino and the Idaho National Laboratory (INL) developed Risk Analysis Virtual Environment (RAVEN), continued development of component fragility mathematical models, and wave impact simulation device development, testing, and analysis.

This report describes FY17 progress on Nuclear Power Plant mechanical component flooding fragility experiments and supporting research. The progress includes execution of full scale component fragility experiments, design and implementation of improvements to the Portal Evaluation Tank, experiment design exploiting the improved Portal Evaluation Tank capabilities, fragility mathematical model development, Smoothed Particle Hydrodynamic simulations and RAVEN coupling, wave impact simulation device design, and pipe rupture mechanics research. Additionally, a component flooding experiments steering committee charter was developed and initial committee member invitations were issued. Various laboratory tours also occurred including a tour for the Idaho State Board of Education.
