Abstract
In this paper, we present an X-ray Absorption Near Edge Structure (XANES) study of chlorine speciation in virgin nuclear graphite of the French UNGG reactors of St. Laurent (SLA2) and Marcoule (G2). Comparable Cl K-edge XANES spectra are obtained for both kinds of virgin nuclear graphite. Spectral analysis shows that chlorine is covalently bound to carbon atom, with a formal valence equal to (−I). Annealing of the samples in the temperature range 200–1000 °C induces a release of chlorine but does not change its speciation and valence.
