LIBRTI_UK. Lithium Breeding Tritium Innovation (LIBRTI) Programme. Information restricted (Safeguards). Proposal for tritium production and for the development of tritium breeding technologies based on the development of special target bounded to a Neutron Spallation source with Demo that no other options as (present or new CANDU-like, devoted HF reactors, RTNS) being reliable. A 20 L of tritium breeding domain with robust passive TRS and simple TSS with minimum residence time (for minimum dwell times when extrapolating to fusion). Innovative solutions for the tritium experimental testing as (A) Active TPR and n-capture sensors; (B) DWT to be potentially considered for simultaneous Dual Power and Tritium recovery; (C) SC_CO2 for HRS and TRS technology; (D) Use of RML for dynamic tritium-mass balance controlled monitoring (New ITOP); (E) Microprinted LM/SCCO2 heat exchangers design. (F) Tritium recovery technologies from SC_CO2. Execution plan discussed.

Main challenge: experimental demonstration of an industrially scalable technique for producing the eutectic Lithium-Lead alloy (Pb-15.7(2)Li), a strategic material in fusion technology, along with the capability for enrichment in 6Li, according to nuclear material standards. Its 4 major objectives are: (1) Establishing the Quality Standard (UNE) for the material in its production, handling, and qualification. Establishment of a national network of characterization and qualification laboratories. (2) Experimental demonstration of a scalable isotopic separation technique for Li(6) (1 kg). (3) Experimental demonstration of a technique for mixing Li-Pb under quality requirements and industrial scalability (1 ton). (4) Key actions towards industrialization in the production of Pb-15.76Li batches. The activities are structured through 22 specific tasks between FUS_ALIANZ, IQS, URV, IDONIAL, and CIEMAT. Subcontracted entities include UNED, IPUL, and Riera Nadeu S.A.

EUTECTICS®: Industrial production of LLE under nuclear QA standard. (1) Assessment of 6Li, lead-lithium eutectic material grades procurement demands for the EU WCLL ITER TBM blanket Program; (2) A Material Production and Qualification Plan (MPQP) for LLE material grades ; (3) A plan for the scoping production of 6Li and Pb-15.7(2)6Li nuclear grades including the selection of 6Li production technique in view of 6LLE TBM procurements (4) Design supported modeling of MHD stirrers for Industrial production of LiPb. (5) Prospecting production trials of LLE and LLE(6)) to confront MPQP. This Project has generated a full capacity to procure Li(6)-enriched Lead-lithium certified nuclear grades in Spain by FUS_ALIANZ and collaborators.
