Comparing Measured and Simulated Reaction Rates in Uranium and Nickel Detectors of the BARS-5M–RUN-2 Reactor Complex

Abstract

Nuclear reaction rates in the nickel and uranium detectors placed at different positions within the reactor cores of the TIRAN nuclear reactor complex are measured. The measured reaction rates are found to be consistent with those simulated using the PRISMA-D Monte Carlo code with the values of neutron constants as quoted in the ENDF-BVI library. Relying on the simulation, the signals of nickel neutron activation monitors are more precisely related to energy releases in the reactor core.
