1D-modelling of differential pressure buildup at clogged containment sump strainers after LOCA

Grahn, A.; Krepper, E.; Alt, S.; Kästner, W.

The present paper reports on our efforts in modelling the pressure drop buildup at sump strainers obstructed by mineral fibrous insulation material after a Loss of Coolant Accident (LOCA). Special attention is drawn to the compressibility of the fibrous filter cake. Comparison of numerical results with pressure drop measurements has been provided.

Keywords: reactor safety; pressure drop; sump strainer blockage; Loss of Coolant Accident
