FIELD: means for identifying fuel assemblies, mainly spent ones, taken out of nuclear reactor or cooling pond and meant for next storage and recovery.
SUBSTANCE: numbered fuel assembly identification zone is illuminated at different angles with different-wavelength pulsed light sources at a time and their image is transferred to several separated color video cameras. Then color images obtained are separated by means of computer according to color of light sources and images obtained are identified including estimation of each number symbol probability. Data obtained are integrated and each of number symbols is finally checked for probability of compliance with this or that value by conducting common analysis.
EFFECT: enhanced reliability and speed of identifying symbols injured with time and under service conditions which are read-out in the course of recording.
