A new Indian concept involving a lead lithium ceramic breeder is being explored. LLCB based tritium blanket modules require tritium extraction from lead-lithium as well as from helium purge gas. This paper addresses the concept of efficiency enhancement using high surface area, low-pressure drop structured gas liquid contactors for tritium extraction from the lead lithium. Conceptual flow schemes for both loops are discussed and critical issues are highlighted. Tritium monitoring systems (TMS) for measurement and monitoring of tritium is also dealt. A fast responding tritium monitor has also been developed for insitu measurement of tritium in water or gas form. It has been tested for liquid effluents.
