The paper proposes a method for reducing the true pore size in oxide nuclear fuel using a well-known histogram for the distribution of the pores cross sections across the polished section. It is shown that the problem of constructing a continuous pore size distribution function from the pore size distribution histogram is incorrect. Histograms showing pore distributions across the polished sections of oxide nuclear fuel sintered under various conditions are obtained. The Scheil-Saltykov method was used to reduce histograms for 3D pore size distributions in uranium oxide fuel.
