THERMAL-HYDRAULICS AND MASS-TRANSFER OF THE COOLANT-OUT-OF-TUBE BLANKET MODEL

This paper reports on the design, modelling and development of a compu ter code for a blanket and its thermal-hydraulic and tritium mass tran sport capability and performance. The model includes all the heat and mass transfer processes that occur in the blanket and allows examinati on of the thermal behaviour with time and under varying thermal load, including the prediction of tritium mass transfer, release, diffusion and recovery behaviour, and corresponding rates in the blanket. The mo del is used to perform scoping and technology assessment studies for p ower plant relevant parameters. The model and code also have the capab ility of analysis of accident scenarios of candidate blanket concepts and testing of the neutronic performance of various material configura tions.
