【 摘 要 】

This report summarizes the design of the ATR MOX Test Fuel Pin Measuring Device. This device makes use of four Magnescale probes and a precision sliding table to make three-dimensional measurements of a short fuel pin (approximately 8 inches) with an accuracy of better than 0.0003 inches. Mathematical fitting is then used to determine the diameter and bowing of the fuel pin as a function of length. This device is currently being applied to fuel pins irradiated in the Advanced Test Reactor (ATR) as part of the Light Water Mixed Oxide Fuel Irradiation Test sponsored by the Department of Energy.
