HTR-PM Simulation Analysis of Accident Conditions Based on vPower Platform

HTR engineering simulator can be achieved by embedding THERMIX code into the vPower simulation environment. The engineering simulator consists of double-module reactors, two steam generators and entire secondary loop system for power generation with a water-steam Rankin cycle. The engineering simulator can be applied to simulate the steady-state operation, but also transient and accident state of HTR-PM. This paper analyzes the trends of reactor power, helium flow, steam generator inlet parameters, turbine inlet parameters and other key parameters under accident conditions, as well as the mutual influence between the two module reactors during accident process. Current simulation results are in good agreement with the design values and safety analysis results of HTR-PM.Copyright © 2014 by ASME
