| dc.description.abstract-translated | Chromium plays a vital role in nuclear reactor systems as an additive to stainless steel improving its corrosion resistance and high-temperature strength, thus necessitating accurate knowledge of its neutron cross-section. This study presents a neutron transmission experiment—referred to as the "broomstick experiment"—conducted at the VR-1 reactor using cylindrical chromium samples and a collimated neutron beam. The experimental setup employed a pencil beam geometry designed to minimize scattered neutron contributions and increase sensitivity to total cross-section minima. Measurements of the neutron spectrum behind diSerent layers of the chromium samples were performed with stilbene scintillation spectrometry in the 1–10 MeV energy range. The experimental spectra behind chromium cylinders of varying lengths (5, 10, and 20 cm) were compared to Monte Carlo simulations using ENDF/B-VIII.0, JEFF-3.3, JENDL-5, and INDEN evaluations. The results reveal discrepancies between simulations and measurements, particularly at low and intermediate energies, indicating the need for continued refinement of chromium nuclear data. The study highlights the importance of integral experiments for validating nuclear data and demonstrates the eSectiveness of the broomstick experiment in providing valuable data for chromium cross-section validation, revealing specific areas where existing nuclear data libraries can be improved. | en |
