Numerical investigations of insulation debris transport phenomena in water flow


Numerical investigations of insulation debris transport phenomena in water flow

Krepper, E.; Grahn, A.

The investigation of insulation debris generation, transport and sedimentation gains importance regarding the reactor safety research for PWR and BWR considering all types of LOCA as well as short and long term behavior of emergency core coolant systems.
A common project in cooperation with IPM-Zittau deals with the experimental investigation and the development of CFD models for the description of particle transport phenomena in coolant flow (see ref. 1). The activities are funded by the German Federal Ministry of Economy and Technology. While experiments are performed at the IPM-Zittau, theoretical work is concentrated at Forschungszentrum Rossendorf.
In the present paper the basic concepts are described and first feasibility studies are shown. During the ongoing work further results are expected.
