29 Evolution of Full Scope Simulator in Korea (Stage IV – Best estimate engineering)

„ Fidelity Improvement by employing BE code as NSSS T/H engine for training simulator • avoid negative training possibility due to overly simplified models and assumptions and can be used as safety evaluation tool for the transient analysis „ Essential technology for developing the state-of-art training simulators • Based on BE codes : USA ( RELAP-R/T, theater.. ), France (CATHARE2 ), etc.

„ Why RETRAN? • RETRAN is one of the most widely used in many utilities in the world. • Most of utilities have RETRAN specialist and input deck data base. • Using the safety analysis input for developing simulator T/H model gives cost and time saving „ Easy for maintenance and upgrade • Easy to replace with an up-to-dated RETRAN if needed • Usually no need to develop / improve NSSS T/H engine for training simulator

30 Evolution of Full Scope Simulator in Korea ARTS(Advanced Real Time Thermal-Hydraulic Simulation)

„ Development of backup calculation model for robustness • Limitation of RETRAN: difficult to simulate LBLOCA, mid-loop operation • Developed to insure the continuous calculation when ARTS fails „ RCS modeling: HEM (Homogenous Equilibrium Model) • Primary system two regions of pressurizer and RCS (mass, energy, momentum) • Secondary side of SGs single region for each SG (mass, energy) • ARTS Properties of all volumes and junctions are obtained explicitly using the calculation results of backup model
