Abstract

Magic angle spinning nuclear magnetic resonance (MAS-NMR) is a very powerful analytical technique for the study of the local structure in materials. However, the analysis of actinide-bearing compounds and their 5f-unpaired electrons remained for a long time elusive mainly because of their well-known high radiotoxicity. Recently, the Joint Research Centre Institute for Transuranium Elements (JRC-ITU) in Karlsruhe (Germany) acquired a 9.4T commercial NMR spectrometer dedicated for the study of actinides-bearing compounds. It has been integrated with a radioactive glovebox and a 1.3 mm commercial probe (rotation rates up to 70 kHz). It has been used on a broad range of materials including fuels, glasses and ceramics for nuclear waste disposal. The presentation will concentrate on applications in the fuel domain.
