Transport packing set for radioactive waste based on a radiation-protective polymeric matrix

Recent Progress in Gd-Containing Materials for Neutron Shielding Applications: A Review

“…Therefore, they have great potential for several radiation shielding applications (e.g., wearable protective devices for the nuclear or aerospace industries) ( Figure 6 ) [ 66 ]. For instance, Yastrebinskii et al [ 67 ] successfully designed a neutron-protective PMC cover with a high concentration of Gd filler for transporting packing containers of SNFs. This section focuses on Gd-containing PMCs and their potential in neutron shielding applications, as well as the effect of Gd particle size on the neutron shielding performance of these PMCs.…”

“…The advent of nanotechnology has greatly facilitated the application of nanomaterials as highly effective fillers/reinforcements, resulting in noteworthy enhancements in the mechanical properties and radiation shielding efficiency of composites [ 67 , 80 ]. There are considerable research efforts devoted to the applications of Gd-based nanofillers in PMCs for radiation shielding purposes [ 63 , 76 ].…”

“…Interestingly, the size effect is strongest at low particle concentrations and declines as particle concentration increases. Prabhu et al [ 67 ] also claimed that the enhancement of radiation shielding efficiency of composites was predominant with Gd nanofillers with decreased size at very low loadings. Although the shielding composites were not tested for neutron absorption in the above two studies [ 67 , 81 ], their findings have offered a new perspective on the role of particle size in material design.…”

“…Generally, PMCs have remarkable ad vantages, such as being flexible, cost-effective, lightweight, and corrosion-resistant [64] Most importantly, the neutron shielding performance of PMCs can be improved by intro ducing neutron absorbers (e.g., B or Gd) as shielding fillers in the polymer matrix [65] Therefore, they have great potential for several radiation shielding applications (e.g wearable protective devices for the nuclear or aerospace industries) (Figure 6) [66]. Fo instance, Yastrebinskii et al [67] successfully designed a neutron-protective PMC cove with a high concentration of Gd filler for transporting packing containers of SNFs. Thi section focuses on Gd-containing PMCs and their potential in neutron shielding applica tions, as well as the effect of Gd particle size on the neutron shielding performance of thes PMCs.…”
