Title:
【発明の名称】燃料棒寸法検査装置の測定精度チェック方法及びこれに用いる校正用ゲージ
Document Type and Number:
Japanese Patent JP3100925
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress the lowering of load factor of a fuel rod dimension inspection device by making simply performing the check of measurement accuracy possible. SOLUTION: A reference gauge 9 for calibration is mounted on a fuel dimension inspection device and such measuring items as total length, bend and the parallelism of end plug fixing is measured similarly to the ordinary work of fuel rod dimension inspection. Then, a displacement gauge for calibration 10 is mounted on the fuel rod dimension inspection device and such measuring items as total length, bend and the parallelism of end plug fixing is measured similarly. When the measurement of each measuring item for the reference gauge 9 for calibration and the displacement gauge for calibration 10 is completed in this manner, whether or not the deviation between each of the measured values is within a specified range is judged. By this, good or bad of measuring accuracy for each sensor and scale of the fuel rod dimension inspection device is checked.
