Project abstract

A full oscillation cycle of methane diffusion flame at 10 bar.

Tri-isotropic (TRISO) coated particles used a nuclear fuel elements in very high temperature reactor (VHTR). The core of my study is to develop a glass-graphite composite (GCC) sintered with spent TRISO particles and justify its safe disposal in the long-term repository. The aim of the project is to encapsulate TRISO particles in alkaline borosilicate-graphite composite as a Engineering Barrier System (EBS). EBS provides barriers to prevent radionuclides migration to the environment once buried in the geological repository. The project considered the safety criteria of radioactive waste disposal and the concept of volume minimization the final waste form.

The project comprises five experimental chapters:

  1. "Glass Melting Techniques used in Radioactive Waste Immobilization" (Published by Journal of Pakistani material society 3-2,1-10,2009)
  2. "Microstructure Characterization of Simulated TRISO particles Embedded in Alkaline Borosilicate Glass" (Published by Journal of Applied Glass science 2-4, p 20-24, 2011 as part of Journal of American Ceramics)
  3. "Interaction of Embedded TRISO Particles with Melt of Alkaline Borosilicate Glass (ABG)" (manuscript accepted by Journal of Nuclear Material, 2011, in the press). Figure 1a and Figure 1b
  4. "Investigation the Chemical Durability of Surface Activated Graphite-Glass Composite encapsulating TRISO fuel particles" (manuscript submitted to the Journal of Nuclear Material). Figure 2a and Figure 2b
