Description

Determining the 235U abundance ratio of fuel pins is a significant stage among quality control in safe operations of reactor. 88Rb, 107Rh, 135I were choosed as analytic target. Relationship graphics of fission yield ration Y-bar88Rb/Y-bar107Rh, Y-bar88Rb/Y-bar135I VS 235U were polted. The simulated fuel element samples of different reactor were analyzed by working curve, and carried on theoretical analysis and experimental research on affection of measurement result by fuel element cladding. In order to testify the accuracy of the method, the simulation sample of 3.03% was measured 5 times respectively, relative standard deviation(RSD) of all tests was less than 5%. (authors)
