Calculations taking into account the influence of grain structure on the effective resonance integral of high-temperature reactor fuel assemblies caused by the use of coated particles are checked by measurements of such fuel assemblies with a lead spectrometer. The effect is quite remarkable and can be clearly seen from the measurements. Calculations show good agreement with our measurements.
