Applications of the technique of LA-ICP-MS to the characterisation of irradiated nuclear fuel
The most frequently used technique in the characterisation of radiated nuclear fuels is its analysis by electronic microsounding (EMPA). However, this technique does not provide the isotopic information needed. To complement the technique an analysis involving laser ablation with mass spectrometry for inductively coupled plasma (LA-ICP-MS) can be used. This paper describes the installation and fitting of an LA-ICP-MS apparatus for analysing highly active solid samples. The technique used in the LA-ICP-MS allows for a qualitative and semi-quantitative estimate of the fission products and actinides present in radiated nuclear fuels to be made. By analysing solids, rather than using wet techniques, the loss of some products through evaporation is prevented. The resulting isotopic spectrum is more complete, giving sufficient resolution to allow study of concentration gradients which are of great interest when researching the characterisation of radiated nuclear fuels.
