dc.description.abstract-translated	Nuclear fuel is organized in nuclear reactor in a form of fuel rods, there is a coolant flowing in the space between rods. These rods are kept in their position by spacer grids. Blockage of a spacer grid by some piece of debris (metal fragment, corrosion product or other foreign material) can significantly alter the flow, decrease heat transfer and increase risk of local overheating. Isothermal flow through a model nuclear fuel assembly is studied by Particle Image Velocimetry (PIV). Blockage is introduced artificially by using circular plug placed at the "star" or "circle" node of the spacer grid. Results reveal that the blockage location leads to diSerent behavior in in terms of wake strength, wake width, fluctuation amplitudes or length-scales.	en
