摘要

The Karlsruhe Sodium Laboratory (KASOLA) is a highly versatile medium size experimental facility located at the Karlsruhe Institute of Technology. The facility is designated for research activities on thermal hydraulics in sodium operated systems for transmutation, accelerator target development, and associated material sciences as well as non-nuclear applications. Furthermore, supporting studies for development and validation of turbulent heat transfer models for system and CFD codes are envisaged. A recent goal of the facility is to demonstrate the feasibility of sodium usage for thermal storage systems and direct energy conversion at high temperatures. To support the construction of the facility, calculations are performed with the best estimate system code TRACE. As a first step, the stationary thermal hydraulic behavior of the loop, like the pressure drop as a function of the mass flow rate or thermal losses to the environment, are evaluated prior to the experiment. Several new models have been implemented into TRACE source code for laminar, turbulent forced convection, natural convection, and the transition between them. With these new capabilities of TRACE, it is possible to evaluate the natural convection performance of the KASOLA loop. The status of the work program is presented.
