Measurement and Analysis of the Fuel Pin Deflection Irradiated in Fast Reactor using the X-Ray CT Image

Katsuyama, Kozo ; Nagamine, Tsuyoshi; Matsumoto, Shinichiro

In order to evaluate the irradiation behavior of fuel pin, X-ray CT test was carried out for the fuel assembly irradiated in the experimental fast reactor Joyo and fuel pin deflection were measured based on the analysis of CT image. It was observed that the deflection of the fuel pins loaded in the outermost array of the fuel assembly were large as compared with the fuel pins loaded in the inner region and the fuel pins fuel situated fronting on wrapper tube were markedly displaced in the direction of wrapper tube.
