Abstract

The sodium-cooled fast reactor (SFR), as one of the most mature and promising Generation IV reactors, is a potential energy source. Load following operation has flexible regulation performance and is suitable for future development trend of grid peaking operation. The paper proposes a coordinate control strategy for the SFR under load following operation mode. Firstly, a simulation platform for the SFR was developed by adopting MATLAB/Simulink library technology. Secondly, a coordinate control strategy under load following operation mode was developed to coordinate primary sodium loop, secondary sodium loop, and feedwater-steam loop. Finally, typical operational transients such as step and ramp load change transients were simulated to validate the developed coordinate control strategy. The simulation results demonstrate that the reactor power has satisfactory flexibility and the system key parameters have good dynamic characteristics, which ensures expected performances of the SFR.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
