Abstract

In Lingao Phase 1 nuclear power plant, violent piping vibration was found during the function test of the pump, especially when the pump was run under small flow.The authors of this article measured the dynamic stress of the piping with strain gauges and gave a fatigue life assessment of the piping with ASME and BS codes.
