“…In HTGR-based power plants, power supply and demand must be balanced by generation or load, so the HTGR requires an automatic control system to track load variations and operate efficiently and stably at the desired power level. Currently, a wide range of control mechanisms have been developed by researchers in the related papers, from dynamic surfaces [171] to optimal and robust control [172], sliding mode control (SMC) [173], fuzzy control [174], deep reinforcement learning [175], neural networks [176], [177], improved PID control [178], dynamic matrix controllers (DMCs) [179], etc. Specifically, [173] designed a nonlinear tracking controller for mHTGR based on the SMC scheme and TS fuzzy technique to achieve the power level control objective under variable load conditions.…”

“…[178] used an improved PID controller to control the start-up, shutdown, and load-tracking control system of a VHTR. [179] used the MPC method based on DMC for supervisory control of NSSS to regulate the NSSS thermal power by adjusting the neutron flux, coolant flow rate, and other set values. Some evolutionary computational algorithms, such as genetic algorithms (GA) [164], can be applied for parameter optimization of HTGR.…”

A small modular reactor (SMR) is a nuclear reactor that is characterized by its smaller size and capacity when compared to traditional large-scale nuclear reactors. An SMR is often categorized as having an electrical output of less than 300MW and is built to be more mobile, safe, and extensible to deploy. It has been established that SMRs can provide economic and flexibility advantages in a variety of industries thanks to the development, study, and use of multiple types of SMRs in recent years. The goal of this paper is to present a comprehensive overview of several SMR types, including light water reactors (LWRs), liquid metal-cooled reactors (LMRs), molten salt reactors (MSRs), and gas-cooled reactors (GCRs). Each type of reactor will be reviewed in terms of its structural design, modeling control implementation, applications, and impacts concerning the power system.INDEX TERMS Digital simulation, mathematical modeling, power system control, reactor design, small modular reactors, nuclear power.

Summary Modular high‐temperature gas‐cooled reactor power station (MHTGR) is the most promising configurations for fourth‐generation nuclear technology. Aiming at the low accuracy of the performance prediction of MHTGR compressor, the paper intends to provide an experimental basis to have deep comprehension about the nexus of loss, passage structure and working conditions, including surface flow visualization, five‐hole probe measurement at the outlet section and surface pressure measurements under different conditions (blade camber angle, incidence angle). The experimentally measured data and images give a deep insight into the influence of blade camber and incidence on the flow structure, loss and blade loading. The vortex system is mainly shaped by the action of the pressure field. When the flow turning angle is large, the effect of the working fluid properties may be inconspicuous on the overall loss of the flow, rather than the tremendous impact on the boundary layer friction loss of attached flow as in the small blade chamber angle passage. For different vortices, the effect of each factor, which may cause losses, is also wax and wane.
