To evaluate the interchannel temperature transfer, the test section was created, the working section of which is a model of two neighboring cells of the peripheral region of the fuel assembly. The experimental setup is equipped with three fuel rod simulators 500 mm long. During the work, the fuel rods were connected in turn to the power source. This made it possible to determine the features of the temperature distribution in the model with uneven energy release. The power of each fuel rod simulator was up to 2000 W. A movable thermocouple and an IR camera were used for measurements.
