Resumo
Thickness measurements of nuclear fuel plates manufactured at the Nuclear Fuel Center of the Nuclear and
Energy Research Institute (IPEN-CNEN/SP) are currently performed using manual external U-shaped frame
micrometers with non-rotating spindles and beveled measurement anvils. Results are then manually recorded on
dedicated forms. To improve the efficiency and the metrological reliability of the process, a novel thickness
measurement system for nuclear fuel plates was developed. This work presents a comprehensive metrological
study of the newly designed measurement system, achieved through the construction of a new apparatus with
automated mechanisms for synchronized movement, data capture, transcription, and processing. The study results demonstrate the metrological adequacy of the developed system and underscore the importance of the
design and structural quality of the measurement equipment. Consequently, the metrological reliability of the
results in the dimensional control of nuclear fuel plates is confirmed.
