[en] Cross and parallel flow induced vibrations were measured in a shortened full scale model of the CRBRP steam generators using water as the working fluid. M easurements were made on five selected tubes, some of which fit through oversize tube support holes. Power spectral density plots were made of vibration parameters at selected locations. Maximum displacement was about 3 mils and occurred at the lower frequencies. The maximum vibrational stress was calculated to be 2000 psi. Measurements of vortex shedding frequencies showed that vortices are not a dominant source of tube excitation. In general, no adverse effects on the CRPRP steam generators were identified which affect service life or structural integrity
