摘要：This article is the second part of the 3D numerical analysis of the thermal and hydro dynamical processes which take place inside the fuel channel of the RBMK-1500 reactor during the interaction between the coolant and the fuel bundles. This article covers the results devoted to the upper part of the fuel channel, meanwhile, the preceding investigation [3] focuses on the processes, which run inside the lower part of the fuel channels of the RBMK-1500 reactor.
