Abstract

This study was undertaken to clarify the alteration process of French LWR synthetic glass leached by distilled water at 250 and 300°C for 28 days. The present experiments emphasize “in situ” identification of the alteration products in small areas (20 × 10−4 mm2 ) along the alteration profile by a specific X-ray diffraction technique.

Experimental assembly: The sample is irradiated by an incident X-ray beam (Co k α, 40 mA, 40 Kv) focused to a 150 μ m diameter. The sample oscillates around a θ central selected position and the diffracted X-rays are detected simultaneously in a 14.5 (2 θ ) solid angle, then recorded by the linear position sensitive detector and stored in a multichannel analyzer.
