This paper describes a concept for a high-performance, inherently safe fusion blanket using helium coolant, beryllium multiplier, lithium breeder, and a vanadium alloy structure. The goals of the design were to explore the possibility of inherent tolerance to loss of coolant and flow accidents while minimizing the cost of electricity (COE). Results indicate high net thermal-to-electric conversion efficiency (45.5%), good energy multiplication (1.64), and excellent afterheat tolerance with a maximum blanket temperature of 760/sup 0/C after 1 yr with no cooling. The calculated COE, however, is approx. 18% higher (0.0405$/kW(e) x h) than other blankets costed on a similar basis by the MINIMARS program because of the projected high cost of vanadium.
