ATHLET Calculations of Selected Experiments at PMK-2

The report deals with results of ATHLET calculations for the Hungarian test facility PMK-2. The test facilty is a 1:2070 scaled
down model of a VVER-440 reactor. The calculated experiments includes a „inadvertent opening of the pressurizer safety valve"
and a „pressurizer surge line break". Both experiments were carried out within the PHARE 4.2.6b project. For the calculations
the code ATHLET mod1.1 Cycle C was used. The results of the calculations were compared with the experimental data.
