Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

To balance IRE for deep penetration, it is necessary for nuclear power plants (NPPs) operates with enough flexibility. To realize the flexible operation, the automatic generation control (AGC) should be developed. In this paper, the adaptive AGC is proposed for SMR-based multimodular NPPs, which has a simple proportional-integral (PI) structure. The corresponding control system of multimodular NPPs with AGC function is also designed, which is constituted by the units of NSSS control, multimodular coordination, turbine speed governor (TSG) and AGC. The adaptive AGC method as well as the plant control system design with AGC function are then applied to two modular high temperature gas-cooled reactor plant HTR-PM. Numerical simulation results show that the newly-built multimodular control system can well stabilize the grid frequency by properly performing the power-level maneuver and maintenance of NSSS modules.
