Rarefaction waves caused by rapid depressurization can lead to significant loads on the piping and structures. The rarefaction wave in the nuclear power plant steam generator tubes during an accident involving a large loss of coolant has been modelled using: — computer code RELAP5/MOD3 — one dimensional code for the simulation of the thermohydraulic phenomena in two phase flow with 6-equation two-fluid model, — a 3-equation homogeneous equilibrium model (HEM) with high resolution shock-capturing numerical scheme. The phenomenon has been modelled using HEM due to negligible nonequilibrium effects predicted by RELAP5 6-equation model. Significant numerical diffusion caused by RELAP5 first order upwind discretization of the convective terms has been successfully reduced by the high resolution shock-capturing method. The Roe matrix for the HEM has been constructed, and Roe approximate Riemann solver and Van-Leer flux-limiter were applied. The accuracy of the RELAP5 and high resolution method results can be improved using the correlation of Alamgir & Lienhard for pressure undershoot due to the delayed flashing inception.
