Description
An elaborate nondestructive gamma spectrometric method for determination of fission product activities ratios, used in the fuel element burn-up measurement, is described. It consists in the self-consistent used-fuel gamma spectrum analysis, in which all the needed data, including spectrometer efficiency, energy calibrations and absorption corrections, are taken from one and the same gamma spectrum, measured with a Ge(Li) spectrometer system. A well positioned cylindrical collimator defines the analysed part of the fuel element. Results of the experimentally obtained and analysed long lived fission products spectra in the energy range between 400 and 2200 keV of the used reactor RA fuel element (2% enriched natural uranium) are given. The fuel was irradiated between two and three years and cooled for 340 and 1819 days (author)

Dat je opis razvijene metode nedestruktivnog gama spektrometrijskog odredjivanja kolicnika aktivnosti fisionih produkata u gorivnom elementu, koriscenog za odredjivanje stepena izgaranja goriva RA. Sastoji se u konsistentnoj analizi gama spektra pri cemu se svi potrebni podaci, ukljucujuci efikasnost spektrometra, kalibracija energije i korekcije na absorbciju, uzimaju iz jednog te istog gama spektra, dobijenog pomocu Ge(Li) spektrometrijskog sistema. Analizirani deo elementa se definise kolimatorom sa cilindricnim otvorom. Dati su rezultati eksperimentalno dobijenih i analiziranih spektara dugo-zivecih fisionih produkata koriscenog RA gorivnog elementa (2% obogaceni prirodni uran) u energetskoj oblasti izmedju 400 i 2200keV. Gorivo je korisceno od dve do tri godine a hladjeno 340, odnosno 1819 dana (author)Files
