ABSTRACT:
A rod straightness measuring system and method. A rod, such as a nuclear fuel rod, is supported and rotated in such a manner that if the rod were straight, it would be rotated about its longitudinal axis and remain straight without transverse translational motion, and in such a manner that if the rod were cambered, it would remain so cambered while supported and rotated. A multiplicity of separated and fixed range finders are placed apart from and directed towards the rod so that they would be directed perpendicular to a straight rod's longitudinal axis. The range finders measure the distance to the rotating rod. Differences in maximum and minimum measurements for each range finder indicate the degree of straightness of the rod. In a preferred system and method, the range finders are placed at known distances from a straight rod, and differences in distance measurements from the known distances for each range finder indicate the degree of rod straightness.
