Thermal-hydraulic analysis of the LACE experiments and its fall-out on the safety analysis of the LWRs containment system

The main results of the LACE analysis are reported in this work. A brief description of the way the four analyzed tests were performed is necessary to the understanding of the results. The main section of this work deals with the analysis of the thermal-hydraulic results of the tests. The conclusions have been pointed out especially during official participation to various international exercises performed as part of the project. Three levels of conclusions are reported in the final section of this report, focussing on the possible fall-outs of the LACE program results on LWRs safety analysis and qualification of best estimate (BE) computer codes, in particular of the FUMO one.
