摘要

The possibility of a flow instability in a fuel assembly during a hypothetical loss-of-coolant accident (LOCA) at the Savannah River Plant (SRP) is currently the subject of many analyses. The occurrence of flow instability is to be avoided because of the subsequent reduction in flow through the assembly, which could lead to damage and/or melting of the assembly. The Bingham pumps, which circulate flow through the reactors, may be susceptible to cavitation because of the decrease in pressure that accompanies a LOCA. Cavitation in the Bingham pumps during a LOCA could reduce the forced flow through the assemblies and thus could promote flow instability. The purposes of this study were to determine the effect of cavitation on the system response of a SRP reactor during a LOCA and to supply the boundary conditions for the detailed assembly calculations necessary to determine the effect of cavitation on flow instability. 5 refs., 6 figs.
