Thermohydraulic studies related to the development of a LWR fuel rod testing capsule
For programmes addressing the fuel rod behaviour under normal power reactor operation, it is required that the typical fuel rod temperatures should already be attained from approximately 150 W/cm LGHR. A 2DT code, extended and tailored for thermohydraulic investigations of LWR fuel rod testing capsules, was used to develop an appropriate irradiation device. In parallel out-of-pile tests with simulation heaters were performed in order to verify the new design. This paper describes the extension of the 2DT code with a two phase heat transfer module, and draws comparisons between model predictions and experimental results. The design adopted for the modified LWR fuel rod testing capsule is presented.
