Resumo
A method of taking account of the maximum temperature of fuel-element cladding and temperature nonuniformity along the perimeter of the fuel elements taking account of interchannel mixing of the coolant in the FA of sodium-cooled fast reactors is described. The calculation of the temperature field using the MIF code with a random distribution of the flow sections of the channels and the energy release of fuel elements using the Monte Carlo method shows that the average maximum temperature of fuel-element cladding lies in the interval determined in the models of tightly packed and maximally open bundles and that the temperature nonuniformity along the perimeter of the fuel elements is higher than in the calculation performed with average parameters of a bundle.
