Within the framework of the french NTP program MAPS, the analysis of the (start‐up/shut‐down) transient sequences whose negative impact on the specific impulsion Isp is important, requires the evaluation of the hydrogen system performance and consequently the development of a simulation computer program. This work induces a preliminary evaluation of the hydrogen system performance under nominal operating conditions. A first approach of the transient operating mode has been simultaneously performed; more specifically the evolution of the core during a shut‐down sequence has been studied in order to improve the residual power evacuation and optimize necessary hydrogen amounts for cooling. Furthermore the ‘‘SIMAPS’’ computer program based on the 3D thermohydraulic code ‘‘FLICA 4’’ is being developed to analyze transient process and its benchmarking under nominal conditions is under way. Its summary presentation is given in conclusion. |
