Abstract

Abstract

Lead-bismuth cooled reactor has great potential in safety, design simplification, proliferation resistance and economic performance. In this paper, the small integrated lead-bismuth cooled reactor is taken as the research object. The helical-coil once-through steam generator (S/G) model based on four-equation drift-flux, the primary coolant system model, the constitutive model and the proportional-integral-differential (PID) control model are established, and the operation control characteristics of the lead-bismuth cooled reactor are studied. The results show that the steady-state calculation results are in good agreement with the design values, and the proposed model can accurately simulate the characteristics of the lead-bismuth cooled reactor. Under the condition of rapid load change, the system parameters overshoot is small, and the reactor power can follow the rapid change of steam flow. The blockage of heat transfer tubes has a great influence on the operation of the reactor, and the steam flow decreases by about 6.7% for each heat transfer tube blocked.
