Abstract
Delayed neutron counting (DNC) was applied in quantitative determination of 235U/238U, quantitative determination of 235U and 239Pu in 235U–239Pu co-existing samples at China Institute of Atomic Energy (CIAE). In this work, natural uranium, enriched uranium and their mixtures were used in the determinations of 235U/238U ratios. The results indicated that delayed neuron counting combined with neutron activation analysis(NAA) and k0-NAA for the measurement of gamma rays emitted by 239U decay is suitable for fast determination 235U/238U ratio. In addition, the contents of 235U and 239Pu in 235U–239Pu co-existing samples can also be determined respectively.
