Nuclear and Radiation Safety| Резюме: | The passive algebraic reconstructive tomography allows to estimate a state of fuel inside fuel assemblies. The analysis of results of reconstruction of radioactivity in fuel pins by volume FA has been carried out. It was offered to use for an estimation of quality of reconstruction of radioactivity in fuel pins the relative dispersion of a deviation of radioactivity in fuel pins in limits of the tomogram, the relative dispersion of a deviation of radioactivity in fuel pins in limits of one lines, the peak deviation of radioactivity in limits of one lines and a histogram of a deviation of radioactivity in fuel pins. It was offered to use simultaneously for reconstruction of radioactivity results of spectrometer measurements for various energy. The analysis of the submitted histograms has confirmed perceptivity of the offer on use several energy for restoration of activity. |
