摘要：
The authors give the results of experiments investigations into the intercassette interaction of the coolant in the WWER-reactor mixed core consisting of TVSA-T and TVSA-12 PLUS. The investigations were carried out on an aerodynamic stand by the method of gas tracer diffusion. An analysis of the spatial distribution of projections of the absolute fl ow velocity and of the propagation of the tracer concentrations enabled the authors to particularize the pattern of coolant flow past the spacer and mixing grids of the fuel assemblies.
