Beryllium Analysis on the Brazing Zone of Zircaloy-4 Cladding
1989
The distribution behaviors of beryllium which may produce a deleterious damage in the zircaloy cladding have been investigated by the X-ray line scanning of EPMA. The results obtained are as follows; 1) The alloy phase formed by the brazing contains ~6.3 mass % of beryllium. 2) The beryllium diffusion in the base metal (cladding and bearing pad) is recognized only in the range ~5 m from the brazing interface.
