Abstract: 

The analysis of programs subchannel, currently used to estimate the parameters of fuel assemblies of a new generation of reactors cooled by supercritical water. The possibility of the use of programs subchannel at the stage of preliminary calculations, the definition and optimization of design and operational parameters. A comparison of programs, shows the benefits of the program MIF, previously developed to calculate the thermal hydraulic parameters of fast reactors with liquid metal coolant. Shows how to estimate the maximum temperature of fuel cladding of the reactor, taking into account factors of overheating. The possibility of evaluation hot spot factors on the basis of the Monte-Carlo method.
