abstract
A detailed RETRAN model of the secondary side of a Westinghouse model E steam generator has been developed to predict steam generator water level and primary side exist (cold-leg) temperature during startup testing and operational transients. These two parameters were identified as important in measuring the behavior of this steam generator RETRAN model. A nodalization study was performed to determine the minimum number of nodes (or control volumes) required in the secondary side to model the response of these two parameters for the transients of interest.
