ACON is suitable for compre- Nuclear safety analyses hensive simulation of containment phenomena during nuclear reactor design basis accidents and to some extent Containment modelling severe accidents. The lumped parameter approach applied enables flexible modeling of various containment Apros compartment systems. ACON is a suitable tool for both safety analysis use and accurate training simulator Validation Containment thermalhydraulics purposes with real time calculation speed. The Apros containment model can be used fully separately or a containment simulation can be coupled with other thermal-hydraulic calculation to create a complete simulation model of a power plant including . the reactor and turbine systems. Modeling of relevant engineering safety features is also included. The paper focuses on the modeling features of ACON and the related validation work which includes the calculations of nearly 50 experiments performed in various test facilities. The validation methodology is dis- cussed and the validation calculations are summarized as a validation matrix. The paper provides a detailed presentation of selected validation cases in which the main studied phenomena are related to general con- tainment .
