Applicability and limits of the MGAU code for the determination of the enrichment of uranium samples

Nuclear forensic investigations: Two case studies

“…110, 144 and 186 keV). The MGAU code was used for the spectrum deconvolution [2]. The analysis gave an average 235 U enrichment of 1.986 AE 0012 (mass%).…”

The jackknife as an approach for uncertainty assessment in gamma spectrometric measurements of uranium isotope ratios

“…The so called enrichment meter is based on the measurement of the 186 keV gamma peak from 235 U [6]. Another method is based on the analysis of peaks in the X-ray region around 100 keV [7]. A third approach is based on the measurement of gamma rays in the ''high" energy region from 144 to 1001 keV [8,9].…”

Verification of nuclear fuel plates by a developed non-destructive assay method

“…In other techniques the assay does not depend on the geometry of the assayed sample. Isotopic ratios of NMs are estimated through utilizing the ratio of simultaneously observed gamma responses from different uranium isotopes, using different X-and/or gamma lines from the same spectrum [13][14][15][16][17][18][19][20][21][22][23]. Monte Carlo (MC) simulation codes could be used for mathematical calibration of the detectors [24][25][26][27][28][29][30][31] to overcome the unavailability of NM standards.…”
