The LOFT small break experiment L3-5 has been analyzed using the RELAP5/MOD2 code. The code version used, Cycle 36.04, is a frozen version of the code.
Three calculations were carried out in order to study the sensitivity to changes of steam generator modelling and of core bypass flow. The differences between the calculations and the experiment have been quantified over intervals in real time for a number of variables available from the experiment.
