Abstract
Gamma spectroscopy using a room temperature CdTe detector has been car ried out in the proximity of a spent nuclear fuel rod. In this context , a compact and transportable monitor, incorporating a planar CdTe cry stal was constructed and installed inside the beta-gamma hot cell. It provided effective shielding for the crystal against the intense backg round. Gamma spectra, with an energy resolution (FWHM) of 7.2 keV at 6 62 keV, were obtained in 600 s counting time, which would allow verifi cation of the burnup to within 10% and cooling time of the fuel to wit hin 3% of the declared values by applying specific isotopic correlatio ns. The good spatial resolution has allowed the use of the monitor as a gamma scanning device.
