Bb. Shriwastwa et al., Rapid non-destructive quantitative estimation of urania/thoria in mixed thorium uranium di-oxide pellets by high-resolution gamma-ray spectrometry, APPL RAD IS, 54(6), 2001, pp. 941-945
A non-destructive technique using high-resolution gamma-ray spectrometry ha
s been standardised for quantitative estimation of uranium/thorium in mixed
(ThO2-UO2) fuel pellets of varying composition. Four gamma energies were s
elected; two each from the uranium and thorium series and the time of count
ing has been optimised. This technique can be used for rapid estimation of
U/Th percentage in a large number of mixed fuel pellets from a production c
ampaign. (C) 2001 Elsevier Science Ltd. All rights reserved.
