Tritium management in HCLL-PPCS model AB blanket

When dealing with activities related to the design and optimisation of the Helium Cooled Lithium Lead (HCLL) blanket, doubts arose in the past about the technical feasibility of the tritium processing system. The questionable feasibility was due to the heavy performance requirements for different tritium processing subsystems, mainly consequence of the high tritium permeation rate from the breeding blanket into the main cooling circuit, which was claimed as an intrinsic characteristic of such a blanket concept. This was directly related to the supposed very low tritium solubility in the liquid lead lithium in eutectic composition.
