Abstract

The pressing demand for efficient dual-function shields against gamma rays and neutrons has driven research. This study enhances polyvinyl alcohol (PVA) attenuation through the simultaneous addition of 10 & 5, 20 & 10, 30 & 15, and 40 & 20 wt% of WO₃ and CdO. The successful incorporation was confirmed by changes in density, FTIR, dynamic mechanical analysis, and optical absorption spectra. Adding 40 and 20 wt% of WO₃ and CdO increased the density by 4.5 times and raised the glass transition temperature from 39.762 °C to 74.423 °C. The mechanical properties showed significant improvement at higher concentrations of WO₃ and CdO. The shielding effectiveness of gamma rays and thermal neutrons revealed significant improvements: 407.4 %, 352.1 %, and 343.3 % for gamma rays at 661.64, 1173.23, and 1332.51 keV, respectively, and 1120.3 % for thermal neutrons. The results highlight the potential of PVA reinforced with WO₃ and CdO for nuclear shielding applications.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
