Two General Electric boiling water reactor jet pumps, a BWR/6 and a BWR/6-218, were tested for flow-induced vibration (FIV) characteristics in the Large Steam Water Test Facility at Moss Landing, CA, during February and March 1978. Tests were conducted at normal reactor operating conditions (532/sup 0/F, 1046 psia and prototypical flow rates) and a variety of off-design conditions. Both jet pumps exhibited acceptable, low level, random FIV characteristics at normal reactor operating conditions. Both jet pumps exhibited similar high level, periodic FIV characteristics at off-design operating conditions. For both jet pumps, the transition from low to high-level FIV was a monotonic, reversible, function of the slip-joint differential pressure (SJDP). Both jet pumps sustained damage due to operation at high-level FIV.
