Abstract
The purpose of this work is to overview the results provided by the simulation of a counterpart experiment reproducing an Intermediate Break Loss-Of-Coolant Accident (IBLOCA) at the ATLAS and LSTF integral test facilities, using the thermal-hydraulic code TRACE5 patch 5 and the Symbolic Nuclear Analysis Packages software (SNAP) version 2.6.8.
The scenario simulates a 13% cold leg IBLOCA under the assumption of the full High-Pressure and Low-Pressure Injections, and the total failure of the Auxiliary Feedwater.
The simulation results are compared with the available data of the A5.2 and IB-CL-05 tests, in the OECD-ATLAS and OECD/NEA ROSA-2 projects, respectively, to evaluate the prediction capabilities of TRACE5 and clarify the causes of the major differences between the transients. Furthermore, these results represent a contribution to assess the predictability of computer codes such as TRACE5.
