Through multi-modular scheme, i.e. the superheated steam flows produced by multiple MHTGR-based nuclear supplying system (NSSS) modules are combined together to drive a common thermal load, the inherent safety feature of MHTGR can be applicable to the large-scale nuclear plants at any desired power ratings. Since the plant power control technique of classical single-modular plants cannot be directly applied to multi-modular plants, it is necessary to develop the power control method of the multi-modular plants. In this paper, the plant power control strategy of the two-modular HTR-PM plant, i.e. the first under-constructed multi-modular high temperature gas-cooled nuclear plant in the world is given, which includes both the feedback loops and control algorithms. Then, the control strategy is verified through numerical simulation, and the simulation results in the cases of plant power step and ramp show the satisfactory performance of this control strategy.
