Description
Dual energy gama-rays transmission method is a new method for the detection of uranium distribution uniformity of dispersion fuel core. The 136 keV and 264 keV high energy of Se-75 radiation source is chosen for the test. HPGe is detected by Gama-ray detector. Under the energy of 264 keV, U and Zr's gamma ray attenuation coefficient, which is far greater than the coefficient at the energy of 136 keV, the content and uniformity of U and Zr in dispersion fuel core were determined. Plexiglass bottles contain Uranium and Zirconium powder are used as criterion specimen for the attenuation measurement and iterative method is used for solve the equation. The results present that the relative errors of detecting system is less than 5%, well meet the requirements. (authors)
