During seismic or blade/impeller loss events, the potential for rubs in rotating nuclear and fossil fuel power plant components is quite high. Generally, such events involve interactions between blade/impeller tips and machinery components. This also includes the possibility of seal casing rubs. The paper develops methodologies to: evaluate the blade impeller-casing rub event; establish the associated stress, strain and force fields; enable signature analysis defining blade/impeller/seal participation; and establish procedure enabling evaluation of blade/impeller/seal fatigue life. Additionally, the paper presents benchmarking examples of prototypical power plant components.
