摘要：
Small lead-bismuth fast reactor(SLBFR) with pool cooling offers inherent safety features, making it suitable for diverse applications such as mobile nuclear power plants and remote power supplies However, conventional control methods often struggle to meet the demands of frequent load adjustments. To ensure the safe operation of SLBFR in the turbine-leading mode, a new control method for the once-through steam generator (OTSG) is imperative. Moreover, enhancing load-following capabilities is essential to meet operational requirements. The model of SLBFR is established in MATLAB/Simulink software to study the characteristics of OTSG operating in the turbine-leading mode. The control system of steam pressure is built by active disturbance rejection control. The load-following characteristic of core power is improved by load feedforward control modified by energy balance. Simulation results demonstrate that the adopted control method enhances the load-following capability of the OTSG. This paper serves as a valuable reference for designing the OTSG control system of SLBFR, contributing to its safe and efficient operation in various settings.
