Discovering, Making, and Testing New Materials: SRNL’s Center For Hierarchical Waste Form Materials
Savannah River National Laboratory researchers are building on the laboratory’s legacy of using cutting-edge science to effectively immobilize nuclear waste in innovative ways. As part of the Center for Hierarchical Waste Form Materials, SRNL is leveraging its depth of experience in radiological waste management to explore new frontiers in the industry.

As part of the French Inertial Confinement Fusion (ICF) program, CEA has developped Cryogenic Target Assemblies (CTAs) for the Laser MegaJoule (LMJ). These targets are filled by permeation with high pressure deuterium-tritium gas mixture. The evolution of the materials physical properties, particularly organic ones (PI and CHx), which compose the target is unknown in these hard conditions. The polyimide and CHx membranes permeation was studied in this context. The hydrogen and helium permeation parameters are unaltered for polyimide membrane after tritium ageing in the 20 K-300 K temperature range:KHe = 3.10-14 exp(-16040/RT) mol.m-1.s-1.Pa-1KH2 = 2.10-14 exp(-16950/RT) mol.m-1.s-1.Pa-1First results for the CHx hydrogen permeation parameters without ageing tritium have been obtained:KH2 = 7.10-13 exp(-10550/RT) mol.m-1.s-1.Pa-1New CHx permeation results after tritium ageing are shortly waited.
