Gamma spectrometry of spent nuclear fuel using a miniature CdTe detector
The application of a planar miniature cadmium tellurium (CdTe) detector for gamma spectrometry has been tested by analysing standard radioactive sources and spent nuclear fuel. The detector was connected to a charge loss corrector amplifier and yielded an energy resolution (full width at half maximum (FWHM)) of 7.2 keV at 662 keV. The application of the CdTe detector to spent fuels resulted in gamma spectra of well resolved photopeaks for the fission products caesium-134 and caesium-137. The ratio of the 2 fission products, complemented by isotopic correlations, verified the burnup of the fuel to within 10% of that declared by the operator.
