Abstract: This report presents some model designs of fusion reactor blankets with low lithium and tritium inventories. The lithium inventory is minimized by using a thin breeding zone which is operated in a soft neutron spectrum. Enriched lithium (28 % up to 90 % $^{6}$Li) is used as breeding material and beryllium is employed for neutron multiplication and moderation. Due to the low lithium inventory, the equilibrium tritium inventory can also be kept to a minimum provided the tritium extraction system is sufficiently efficient. A parametric study has been performed to investigate the relevant neutronic and photonic characteristics of this blanket : concept. Different blanket models are compared with respect to their breeding potential, the nuclear heating,and the lithium, beryllium, and tritium inventories involved. The advantages of low lithium and tritium inventories from the safety point of view are weighed against the drawbacks, like the need of enriched lithium, the large beryllium inventory, and the contamination of the coolant with tritium produced in beryllium.
