Keywords:Drift flux model, Rod bundle, Void fraction, RELAP5

A drift flux correlation was developed by using low flow data systematically taken from a well-scaled rod bundle test facility. The correlation was implemented in the RELAP5/MOD3 code, and the void fraction prediction performance was compared with the EPRI correlation which was installed in the original RELAP5/MOD3 code.
