Abstract
This presents results of Phase II of CEC thermal-hydraulic benchmark exercise on Fiploc verification experiment F2 in Battelle model containment, experimental phases 2, 3 and 4, organized/ sponsored by Commission of European Communities for understanding and analysis of long-term thermal-hydraulic phenomena inside containments during and after severe core accidents. This benchmark exercise received high European attention with eight organizations (six countries) participating with eight computer codes during phase 2. Altogether 18 results from computer code runs were supplied by participants and constitute the basis for comparisons with experimental data here. This reflects both the high technical interest in, as well as complexity of, this CEC exercise. Major comparison results between computations and data are reported on all important quantities relevant for containment analyses during long-term transients. These comparisons comprise pressure, steam and air content, velocities and their directions, heat transfer coefficients and saturation ratios. Agreements and disagreements are discussed for each participating code/institution, conclusions drawn and recommendations provided. The phase 2 CEC benchmark exercise provided an up-to-date state-of-the-art status review of the thermal-hydraulic capabilities of present computer codes for containment analyses. This exercise has shown that all of the participating codes can simulate the important global features of the experiment

This exercise has shown that all of the participating codes can simulate the important global features of the experiment correctly, like: temperature stratification, pressure and leakage, heat transfer to structures, relative humidity, collection of sump water. Several weaknesses of individual codes were identified, and this may help to promote their development. As a general conclusion it may be said that while there is still a wide area of necessary extensions and improvements, the present containment codes represent a good basis for multi-compartment modelling (Abstract Truncated)}
