Axial neutron flux density distribution in RBMK-1000: reconstruction using the Prizma-M program

A computational-experimental procedure for reconstructing the axial neutron flux density and power-release distributions using the Prizma-M program is described. An approach to reconstructing the axial neutron flux density and power-release distributions in the RBMK-1000 assembly channels by using extended detectors with a hafnium dioxide emitter to scan the core is presented. This approach made it possible to compare the reconstruction accuracy of the semi-empirical and computational-experimental procedures used in Prizma-M. It is shown that the reconstruction error for the axial neutron-flux density distribution does not exceed the attested error of the Prizma-M program.
