Creators

Description

The present invention provides a device for measuring the shape of a fuel assembly having high reliability and capable of measuring the shape of a fuel assembly automatically while reducing influences such as fluctuation. The average of deviation between the position of a fuel rod obtained directly by an image signal, a reference position of the fuel rod obtained based on the end portion of a grid obtained by the image signal and a design value is determined to obtain a fluctuation f. Then, the fluctuation f is subtracted from the position of the fuel rod to correct the fluctuation error thereby enabling to obtain the position of the fuel rod. (N.H.)
