Abstract. In order to investigate the effects of bypass flow and power change and deviation on radial temperature difference of the helium flow entering the steam generator, model experiments and simulation calculations are proposed to evaluate the Thermal Mixing Performance (TMP) of the thermal mixing structure at Pebble-bed Module High Temperature gas-cooled Reactor (HTR-PM) core outlet. The experiments on Test Facility -Hot Gas Mixing (TF-HGM) are carried out to observe the influences of bypass flow and reactor power deviation. Simulation calculations are conducted for the mixing structure of TF-HGM and HTR-PM. According to the results of experiments and CFD simulation, the maximum radial temperature difference at the outlet of the mixing structure fulfils the requirement by steam generator, under all considered conditions. In addition, the TMP obtained by the temperature difference between main flow and bypass flow is suitable for the experiment and the simulation results while the new definition of TMP integrating specific heat, flow rate, inlet position and thermal uniformity needs further improvement.

At present, large water demand and carbon dioxide (CO2) emissions have emerged as challenges of steam injection for oil thermal recovery. This paper proposed a strategy of superheated steam injection by the high-temperature gas-cooled reactor (HTR) for thermal recovery of heavy oil, which has less demand of water and emission of CO2. The paper outlines the problems of conventional steam injection and addresses the advantages of superheated steam injection by HTR from the aspects of technology, economy, and environment. A Geographic Information System (GIS) embedded with a thermal hydraulic analysis function is designed and developed to analyze the strategy, which can make the analysis work more practical and credible. Thermal hydraulic analysis using this GIS is carried out by applying this strategy to a reference heavy oil field. Two kinds of injection are considered and compared: wet steam injection by conventional boilers and superheated steam injection by HTR. The heat loss, pressure drop, and possible phase transformation are calculated and analyzed when the steam flows through the pipeline and well tube and is finally injected into the oil reservoir. The result shows that the superheated steam injection from HTR is applicable and promising for thermal recovery of heavy oil reservoirs.
