This paper presents all the stages involved in the procedure for the determination of the shape of a fuel assembly, which is an essential part of a nuclear power plant and can only be handled underwater. Phototriangulation is used to obtain orientation elements, taking into account light refracting surfaces. Stereomodels are then set up for analytical restitution and the shape parameters for the object can be obtained. The project is a typical example of high precision underwater photogrammetry.
