The engineering simulation system for HTR-PM

The engineering simulation system (ESS), designed for the demonstration project of HTR-PM in the Shidao Bay Nuclear Power Station, can be served as initial training of the operators, verification of the control system and operational procedures, etc. Based on vPower, the simulation platform, the ESS has established a full-scale dynamic model except the electronic protection system. The ESS can accurately simulate the start-up, shutdown, normal operations and accidents of the HTR-PM. In this paper, the authors introduced the ESS components, primary loop, reactor core modeling, control systems and main control room simulations.
