Determination of the Characteristics of Neutron Field of the IGRIK-2 Reactor Using the Neutron Activation Method

The energy spectra of neutrons in the experimental channel, in the window, and behind the biological shielding of the core of the IGRIK-2 pulse nuclear reactor was measured using the neutron activation method. Approximately 15 neutron activation detectors were employed. The neutron spectrum reconstruction was performed using the method of directed divergence minimization. A comparison of the main integral characteristics of the neutron field with numerical Monte Carlo calculations is presented.
