International Classification:

G21C 1700

US Classification:

376248

Abstract:

A nuclear fuel identification system for use in nuclear power plants has an imaging system having a video camera and an array of illuminators surrounding the video camera and positioned to shine onto a nuclear fuel cell. The illuminators are sequentially activated to provide a series of images each having a different shadow pattern. These images are then digitized and stored until a complete set of the images are available. At that time, the images are superimposed and optimized for improved contrast. By viewing the distinct shadow patterns on the nuclear fuel cell, the identifying markings are readily visible. In addition to the shadow imaging system, a variety of laser devices are used to accomplish similar image generating functions. Such laser devices include a laser scanner, a distance laser device, an interferometer, a holographic interferometer, and a bi-refringent crystal prism.
