Availability Notice


The FIX-II split break experiment No. 3051 has been analyzed using the RELAP5/MOD2 code. The code version used, Cycle 36.04, is the frozen version of the code.

Three calculations were carried out to study the sensitivity of various parameters to the change of break discharge and passive heat structures. The differences between the calculations and the experiment have been quantified over intervals in real time for a number of variables available from the measurements during the experiment.
