“…Different shields with different densities and thicknesses made from dispersed Pb, depleted uranium U, depleted uranium dioxide UO 2 , as well as the shields with initial density of the Fe and U are considered. The long-lived isotopes: 134 Cs, 137 Cs, and 154 Eu are chosen as sources of SNF gamma-rays [7]. In Fig.…”

“…The spectral composition of the SNF gammaradiation changes with the SNF cooling time due to different half-lives of long-lived isotopes. Isotopes 134 Cs, 137 Cs, and 154 Eu were shown in [7] to make the main contribution to the spectral composition. Fig.…”

“…The elemental composition of the fuel emission zone, which is planned to be transported in the TCs to the storage by the dry method, was modeled by homogeneous SNF with a density of 3.5 g/cm 3 containing 238 U 52.3%, 40 Zr 25.8%, 26 Fe 14.6%, 16 O 7.3% [8]. It is shown in [7] that the flux of -quanta on the surface of the source is determined by the near-surface layer of SNF. As the initial characteristics of -quanta, the energy and angular distributions of -radiation from a layer of homogenized SNF ≈ 10 cm thick were used.…”
