Abstract

A nuclear fuel identification code reader has an optical sensor for detecting a first nuclear fuel identification code marked on a fuel assembly and an ultrasonic wave sensor for detecting a second nuclear fuel identification code marked on the fuel assembly. It further has first means for recognizing the nuclear fuel identification code based on information derived from the optical sensor and second means for recognizing the nuclear fuel identification code based on information derived from the ultrasonic wave sensor. When the nuclear fuel identification code cannot be recognized by the first means, the detection by the ultrasonic wave sensor and the recognition of the nuclear fuel identification code by the second means are effected. The nuclear fuel identification code can be recognized in a short time with a high accuracy.
