Tritium processing and containment technology for fusion reactors. Annual report, July 1975--June 1976

Tritium permeability of structural materials and surface effects on permeation rates

“…In an equilibrium mixture of protium and tritium the pressures of HT and T are mutually dependent, equation 5. If the pressures were independent as sometimes considered, the solubility of tritium atoms would be…”

“…Some permeation impedance factors that could be expected with laminated metals have been presented [5,6], and the current evaluation of lamination techniques is that they are not practical with current technology and materials.…”

Uncertainties in modeling of consequences of tritium release from fusion reactors. Plasma Fusion Center No. PFC/TR-79-5

“…The latter includes the breeding blanket and blanket separation system. The waste streams from the above processes * are two possible release pathways [5,[23][24][25].…”

“…In the event of breakdown of the separate 23-systems, stored tritium will prevent.power plant shutdown. As blanket designs call for breeding ratios greater than one , the excess tritium will be stored until removal to other facilities [25].…”

“…The first systems, the plasma.exhaust system, is the most constrained by non-environmental factors and is determined by the plasma confinement scheme [24,25]. For example , the remaining unburned fraction of the input tritium to the plasma varies from 450% for inertial confinement schemes to %95% for magnetic schemes.…”
