The results are presented of independent verification studies performed on the steam generator component with the RELAP4/MOD6, Update 3 computer code, during the blowdown phase of the loss-of-coolant accident. RELAP4 steam generator component models were driven with measured boundary conditions from LOFT and Semiscale blowdown experiments, and the results were compared to test data. The sensitivity of the calculated results to steam generator model nodalization, code options, uncertainty in driving flow and changes in heat transfer coefficients was determined. Steam generator instrumentation requirements and the need for system effects studies are also discussed.
