Abstract The HTR-10GT inventory control characteristics were analyzed to design a system with low recuperated effectiveness. The system was modeled using a simplified model based on reasonable hypotheses and numerical simulations of the entire system model. The results illustrate that the helium mass flow rate decreases as the load decreases but at a slower rate with both following approximately quadratic relations. The regenerator effectiveness is improved which improves the cycle efficiency; however, the efficiency is reduced by temperature ratio decreases, several components deviating from their design operating points and Reynolds number effects. The Reynolds number effects also negatively impact the compressor stability. This study provides reference information for high temperature gas-cooled reactor (HTR) cycle design and operation.
