Abstract

At the Institute for Neutron Physics and Reactor Technology (INR) of the Karlsruhe Institute of Technology (KIT) investigations are devoted to the further development and qualification of sub-channel and system codes. A new sub-channel code named SUBCHANFLOW is being developed and validated at INR. It is a modular code programmed in Fortran-95 with dynamic memory allocation, use of SI-units and including many fluids like liquid metals and water, helium and air. The current validation work is focused on PWR relevant phenomena using the NUPEC PSBT benchmark data for void fraction and critical power.

In this contribution, the main features of SUBCHANFLOW are described and the status of the validation is presented.
