Tests of experimentel low neutron poisoning fuel assemblies in reactor SM
The paper presents the heat rate distribution, thermal flux density and burnup for thee experimental fuel assemblies (EFAs) containing low newtron poisoning fuel rods evaluated both experimentally anf by calculated simulation of their operation in the SM reactor loop facility. The EFAs thermophysical parameters are considered. The key cotrolled test parameters are presented. All EFAs with low newtron poisoning fuel rods have been sucsessfully tested; they preserved their perfomance under heat rate, thermal load and burnup typical for the operating conditions in the modernized SM core.
