%X abstract lowbackground gamma spectrometry was applied to analyze the uranium enrichment of the nuclear fuel used in the instec sub critical ensemble. the enrichment was calculated by two variants: an absolute method using the monte carlo method to simulated detector volumetric efficiency, and an iterative procedure without using standard sources. the results confirm that the nuclear fuel of the ensemble is natural uranium without any additional degree of enrichment.
