Dosimetric experiment at the VVER-1000 reactor of Rivne NPP unit No. 3

A detailed description of the dosimetric experiment to determine the characteristics of the neutron field at the locations of surveillance specimens at Rivne NPP Unit No. 3 is presented. Through the complex analysis of the experimental data, the presence of general regularities in the behavior of neutron spectrum characteristics, such as the spectral index, at these locations was identified. A comparison of the calculated and experimental data was carried out, demonstrating that the MCSS code package is suitable for determining the irradiation conditions of surveillance specimens, particularly when developing an upgraded program.
