Real-Time Simulation Platform for the Design and Verification of the Operation Strategy of the HTR-PM

Abstract

Because of the inherent safety feature, the modular high temperature gas-cooled reactor (MHTGR) has been seen as one of the best candidates for the next generation of nuclear power plants. Power-regulation is a key technique to provide safe, stable and efficient plant operation for the multi-reactor-module power plants. Based on the successful design and operation of Chinese test high temperature gas-cooled reactor HTR-10, the high temperature gas cooled reactor pebble-bed module (HTR-PM) project is proposed. Since the HTR-PM is composed of two interconnected nuclear steam supply system (NSSS), the operation strategy of the multi-reactor-modular HTR-PM is different from that of those one-reactor-modular high temperature reactors such as HTR-10. In order to design and verify the operation strategy for HTR-PM, it is necessary to establish a real-time simulation platform. The design and development of this platform is presented in this paper.

Model-Free Coordinated Control for MHTGR-Based Nuclear Steam Supply Systems

“…The OTSG model adopted the moving boundary model given in [23]. The code was developed based on VC++ [24], and this simulation was done by using this software. Actually, both the space-dependent reactor models given in [22,23] and point model Equation (1) can describe the NSSS dynamics.…”

“…The dynamic model of the second-loop system gives the feedwater temperature and pressure for the dynamic model of the NSSS. In the numerical verification, the simulation software adopts the software given in [24] which contains the dynamics models of the NSSS as well as the secondary-loop. Moreover, from the above Theorem 1 and Comment 1, the NSSS coordinated control law can be written as Equations (16)- (18), and can also take the form as Equations (16), (31) and (32).…”

“…However, due to the mismatch between the real and designed NSSS parameters as well as that between the dynamic features of the real and Furthermore, the parameters of the NSSS models for control design and simulation are given by physical and thermal-hydraulic design. It was verified that the model and software given in [22][23][24] can provide credible dynamical simulation for the HTR-PM plant. The theoretical and simulation results in this paper show at least that the coordinated control law determined by Equations (16), (31) and (32) can be implemented in the practical engineering.…”

Saturated Adaptive Output-Feedback Power-Level Control for Modular High Temperature Gas-Cooled Reactors

“…The OTSG model is just the moving boundary model presented in [21]. Furthermore, the model of the steam turbine and that of the electrical generator are also included in the simulation code [22]. The structure of the closed-loop given by this model and the saturated adaptive output-feedback power-level control proposed in this paper is shown in Figure 3.…”
