Abstract: 

This paper presents the results of determination of power density and burnup distribution throughout the sections of three experimental fuel assemblies with increased uranium content in the rods (6g U235), obtained under calculated and experimental simulation of their operation conditions in the SM research reactor core. The mode of these distributions change during irradiation is analyzed. Thermal physic parameters of experimental FA rod operation are examined. The essential controlled tested parameters are given. It is shown that the reactor FA with increased fuel load stood well the total cycle of the reactor tests retaining its operational integrity under energy release, thermal load and fuel burnup appropriate to operational conditions of the modernized reactor core.
