== Description of the project ==

The eutectic alloy of lithium and lead [15,7(2) % at Li with exact composition yet to be certified] is a functional tritium regenerating material and "base of design" for fusion reactors under construction, ITER and future (DEMO).
ITER will require tons of the alloy as material in the systems (TBM, Test Blanket Modules) together with tons of the material for the ongoing experimental programs around the world: in the EU, Japan, India, the United States , Korea and China. The material was born at the end of the 70s as a proposal for laboratory material [D.K. Sze (INEL, United States), v. Coen (JRC Ispra, EU)] on a laboratory scale far from the quality standards of a nuclear material.
Industrial and development returns in the coming years in the EU alone are estimated at around €40 million, depending on certain programmatic variables and the demonstration of its manufacture under Nuclear Material standards (IAEA Standards, RCC_MR Codes, ISO, ASTM,...) represents a technological challenge of the first order and is, without a doubt, an enormous opportunity for potential contribution and industrial returns from Spanish companies to ITER. Producing the alloy without quality assurance is not high-tech and some well-known laboratories in the world do it. Producing the alloy with the required quality assurance of a nuclear material and whose characteristics affect the safety of the reactor, is a true high-tech challenge in aspects related with: (1) the final certification of the title in lithium, (2) the homogeneity without segregation of lithium at sub millimetric scales, (3) the extreme control of impurities and (4) the demands of certified characterization of its functional database under standards as nuclear material. The production of the eutectic alloy for its final use in ITER (N, TT, IN phases of TBMs) requires the capacity to produce significant quantities of 6Li and the demonstration of an industrially scalable and quality-assured alloying technique. Our Project aims to demonstrate the manufacturing capacity of the material with the complete Quality Assurance of the eutectic as nuclear material from an industrially scalable technique to meet the assessed supply demands in the EU and in other ITER Programs.
The main challenge of the project consists of the experimental demonstration of an industrially scalable production technique of the eutectic alloy of Lithium-Lead (Pb-15.7(2)Li); along with the enrichment capacity in 6Li, all under Nuclear Material Standards.
Its 4 main OBJECTIVES: (1) Establishment of the Standard (UNE) of Quality of the material in its production, handling and qualification. Establishment of a national network of characterization and qualification laboratories. (2) Experimental demonstration of a scalable Li(6) isotopic separation technique (1 kg); (3) Experimental demonstration of a Li-Pb mixing technique under quality requirements; industrially scalable (1 Tn); (4) Key actions towards industrialization in the production of lots of Pb-15.76Li.
To achieve the Objectives of the Project, the activities are structured in the realization of 22 specific tasks of public-private collaboration between our Company FUS_ALIANZ and the Chemical Institute of Sarrià, the Rovira i Virgili University, CIEMAT, IDONIAL and CIEMAT. Nominated subcontractors are UNED, IPUL (Latvia) and Riera Nadeu S.A.
