COUNTING TECHNIQUES IN THE RADIOCHEMICAL DETERMINATION OF U-235 FISSION BURN-UP

Technical Report ·
OSTI ID:4175785
The burn-up in U/sup 235/ fuel samples was determined by a combined radiochemical and mass spectrometric technique. Total fissions were determined by a radiochemical measurement of fission product Cs/sup 137/ using the cesium perchlorate method. U/sup 235/ and U/sup 236/ were determined by mass spectrometry using U/sup 233/ as an internal standard. The determination of Cs/ sup 137/ was found to be limited by the presence of Cs/sup 134/, this limitation being a function of the flux energy spectrum to which the fuel was exposed. The calculated Cs/sup 134//Cs/sup 137/ ratio is presented as a function of burnup for a thermal flux of C/F = 0.17. (C.J.G.)
