MASS-SPECTROMETRIC ANALYSIS OF SUB-NANOCURIE SAMPLES OF URANIUM AND PLUTONIUM
Increasing levels of the radioactivity of reprocessed fuels lead to higher occupational radiation doses. Transport delays of highly active samples are also increasing because of more stringent regulations. The development of multiFaradaycup detectors in thermal massspectrometry makes it possible to scale down considerably the size of reprocessing input samples. This reduces the radiation hazard involved in preparing the massspectrometric samples and eases the transport situation. A method based on the flash evaporation of 1 ng size samples of Pu has been developed which has an accuracy comparable to that of previous techniques. A program has been written allowing the automatic recording of up to 8 masses during an evaporation step of between 100 and 300 seconds. A description of the technique is given.
