The main technical characteristics of the KMS stand as a large-scale model for NPP containment with VVER are presented. It is shown that this stand can be used to study three-dimensional heat and mass transfer processes in the containment atmosphere and to test systems and equipment used in NPP with VVER under close to anticipated and unanticipated accident conditions. In the future, with appropriate development work and additions to the stand it will be possible to study the rate of removal of aerosol particles having different chemical properties, perfect new designs of catalytic hydrogen recombiners and test equipment with the limiting parameters of the containment atmosphere. © 2014 Springer Science+Business Media New York.

Pressing questions concerning experimental modeling of thermohydraulic processes in NPP containment are examined. Domestic and foreign stands are briefly reviewed. It is shown that the KMS large-scale stand is necessary in order to obtain preliminary experimental data on the three-dimensional thermohydraulic processes occurring inside NPP containment and to verify modern computational codes. © 2014 Springer Science+Business Media New York.

Domestic and foreign data on free convection along vertical heated plates and tubes are analyzed. It is shown that the difference between the heat-emission coefficients during free convection can reach 70%. Heat emission along vertical tubes, especially in turbulent air-flow regimes, has been little studied. Meanwhile, a regime close to free convection complicated by heat exchange, for which a correction is made in the closure relations pertaining to heat emission for computational codes, is realized in the passive heatremoval system for the containment. Direct numerical modeling of free convection along vertical plates and tubes is performed. © 2014 Springer Science+Business Media New York.

The main elements of a mathematical model and test results for the specialized code PGS-TK to be used for calculating the flow of a multicomponent steam-gas mixture in the containment of a power-generating unit in NPP with passive heat-removal and volumetric and surface condensation of steam are presented. It is shown that owing to the modern mathematical models and numerical methods the code makes it possible to perform accurate calculations of the containment temperature and pressure for an unanticipated accident without using any adjustable parameters or specific experimental approximations. © 2014 Springer Science+Business Media New York.

The EUR-required passive system for protection against unanticipated accidents in nuclear reactors has been developed. This system and the computational results obtained using three-dimensional computer codes are described. The experimental data are compared with numerical experiments performed using three-dimensional hydrodynamic codes and the KUPOL-M lumped-parameter code. The experiments made it possible to refine the closure relations used in integral codes. © 2014 Springer Science+Business Media New York.
