The degradation of polyethylene (PE) from radiation sources with both thermal and nuclear interactions show sensitivities towards oxygen and air. Characterization of the sensitivities in both inert and oxygenated atmospheres can be characterized by thermogravimetric analysis (TGA). Under argon, the thermal degradation of PE follows a random scission pathway that has activation energy of ~229 kJ mol -1 . The activation energy of PE is reduced by ~30% when 1% air is added to the inert argon atmosphere, illustrating the impact of oxygen on the degradation of PE. This effort seeks to diminish degradation of PE waste containment bags and extend their lifetime, thereby, reducing the cost and worker exposure risk. The project evaluated the use of oxygen scavenger nanoparticles to mitigate the deteriorating effects of oxygen on polymer physical properties and reduce polymer degradation. The thermal degradation of PE composites with various additives were tested and two additives showed promising results approaching the activation energy of pristine PE in an inert atmosphere. This activity was sponsored by the EM Office of Technology Development through SRNL's Technical Task Plan SR091701.

Developing radiation tolerant polymer nanocomposites using C₆₀as an additive

Abstract: The attenuation of alpha particles is modelled using Monte-Carlo N-Particle Extended software. Using tandem Van de Graaff accelerator tests, it is shown that doping with C60fullerene can significantly enhance the lifetime of polymers in alpha radiation environments.
