Reconstruction of the fields of physical quantities in RBMK

The authors propose a new approach to the determination the fields of physical quantities in RBMK and the correction. of starting data for the neutron-physical calculation. The neutron flux density field is reconstructed by fitting the computed data to the indications of the intrareactor monitoring sensors. The macroconstants in the neutron-physical calculation are then corrected in order to decrease the methodical error of the calculation to a level determined by the model used. The proposed algorithm can be used as a supplement to the existing algorithm in the centralized control system. It can be used to calibrate separate sensors, determine the temperature fields and reconstruct the energy-release and neutron flux fields with very high accuracy.
