A conceptual design of a helium-cooled blanket for the Next European Torus double-null plasma configuration with a neutron wall load of 1 MW/m/sup 2/ and 600-MW fusion power is presented. The outboard blanket is made up of self-supporting canisters containing the beryllium multiplier in the form of plates. The 6-mm-wide gaps between the plates contain a bed of 0.5-mm Li/sub 4/SiO/sub 4/ pebbles. The helium purge flow at 0.1 MPa carries away the tritium produced in the bed. The first wall of stainless steel with a graphite tile protection is cooled by toroidally running helium tubes. The minimum and maximum temperature in the pebble bed is 300 and 600/sup 0/C, respectively. Based on the LISA-2 experiments, this means a tritium blanket inventory of 400 g. The daily tritium production is 96 g and the three-dimensional real tritium breeding ratio is 1.04 for a /sup 6/Li enrichment of 90%.
