Numerical investigations of the transport of submerged insulation particle

Cartland-Glover, G.; Alt, S.; Kästner, W.; Krepper, E.

A numerical investigation of insulation debris transport and sedimentation is being performed as part of a joint research project with the Institute of Process Technology, Process Automation and Measuring Technology (IPM) Zittau. The study considers the impact of the transport of insulation wool debris on the long-term behaviour of emergency core coolant systems during all types of LOCA that occur in PWR and BWR. In order to implement models into computational fluid dynamic codes (CFD), the models that characterize insulation debris (particle buoyancy, drag, turbulent dispersion and the fluid-particle mixture viscosity) must be tested. Experimental investigations are being performed at the IPM-Zittau to provide detailed information with which the numerical models can be validated.
