LOCA Analysis for the Basic Design of HANARO Fuel Test Loop

Abstract

Basic design of HANARO FTL is almost done, and this paper presents the preliminary LOCA analysis for the basic design of a fuel test loop using MARS code, which is being developed by KAERI for the simulation of a wide variety of PWR system transients. The focal points are on the thermal-hydraulic behavior of fuel as well as the pressure response in a shielded room where the process equipment are located. Through the analysis, the integrities of fuel and shield room were confirmed.
