The results of RELAP5 post-test analysis of 3 tests performed on the PMK integral test facility are presented and discussed. The Hungarian facility PMK is a scaled-down model of NPP with VVER-440/213 reactor. The code version RELAP5/MOD3.3 Path02 has been assessed against the experimental data from the tests T2.1, T2.2, and T2.3. The tests were focused on medium-break LOCA without HPSI. Generally, RELAP5 predictions are in very good agreement with the measured data.
