At present, no systematic accident management has been implemented in Paks NPP of VVER-440/213-type nuclear power plant. However, results of the safety reassessment of the Paks NPP showed that one group of the measures to enhance the safety is the modernization of emergency operating procedures, including the implementation of accident management. Report is based on experimental results obtained on the PMK-2, an integral-type facility of the Paks NPP. The purpose is to study the application of secondary and primary side bleed and feed procedures to prevent the core damage for beyond DBA accident sequences. Report contains items as: assessment of the effectiveness of the operator interventions; performing accident management analyses for the PMK-2 facility; experimental results on the accident scenarios selected; computer code verification; assessment of the applied procedures.
