Hydraulic Performance of Pump Suction Inlets for Emergency Core Cooling Systems in Boiling Water Reactors.

摘要

The document reports on the hydraulic performance of representative Boiling Water Reactor Residual Heat Removal suction inlet configurations; Mark I and Mark II and III designs. Parameters of interest were air-ingestion, vortex tapes, pipe swirl, and pressure loss coefficient. Tests were conducted with nearly uniform and non-uniform inlet approach flows. Flows and submergences ranged from 2000 to 12000 gpm per pipe and 2 to 5 ft, respectively, giving a Froude number range from 0.17 to 1.06.
