Abstract

The results of metrological studies of the field of the experimental channel of the research nuclear reactor OR (experimental base of the NRC “Kurchatov Institute”) with a capacity of 0.1–300 kW are presented. The empirical dependence of the contribution of the absorbed dose of gamma radiation during the raising and lowering reactor power in the total absorbed dose during the irradiation in the reactor and absorbed dose rate from a power reactor OR in the steady state. Based on these results, the absorbed dose and absorbed dose rate of gamma radiation can be pre-calculated. According to metrological studies results, the experimental channel of the reactor OR was certifi ed in terms of the absorbed dose rate of gamma radiation as a specialized source of gamma radiation spatially combined with the modeling reference field of neutrons. The specialized source is designed for calibration of special-purpose measuring instruments and testing for radiation resistance of products operating in conditions of mixed gamma-neutron radiation of nuclear reactors.
