Mathematical model applied to permeation problems of process designs for tritium recovery from liquid blankets

摘要: A mathematical model has been developed to determine the amount of tritium that permeates cooling circuit a breeding blanket containing liquid eutectic alloy 17Li-83Pb. This model, which applied phase 2A International Tokamak Reactor/Next European Torus project, is used predict effect operating conditions blanket, as well those spray tower employed recovery unit, and kinetic parameters for permeation desorption processes. The results this theoretical study indicate permeated proved be not very different maximum (10.82 kPa/sup 1/2/ . m/sup 3/(mol T)/sup -1/) minimum (0.7 values Sievert's constant (K/sub s/) existing in literature. amount, moreover, can reduced 0.1 0.01 g/day by presence small oxide barriers (a reduction factor ..cap alpha..approx. =100) on tubes easy tower, include droplet diameter 0.5 mm; pressure 0.13 kPa at 673K; residence time s.
