Four prototype BWR/6-238 jet pumps (two jet pump pairs) were tested to determine their flow-induced vibration (FIV) characteristics in the High Flow Hydraulic Facility, (HF)/sup 2/, over the period June to September 1978. Tests consisted of operating the jet pumps, which were heavily instrumented with accelerometers, pressure transducers and strain gages, at the design operating condition, as well as at numerous off-design drive flows and M-ratios, and at temperatures between 70/sup 0/F and 180/sup 0/F and at 455 psig. Results were combined with those from past jet pump tests to predict the response at reactor temperature (533/sup 0/F). Major conclusions reached related to the BWR/6-238 jet pump are presented.
