One of the primary requirements for breeder blankets in commercial DT fusion reactors is to produce sufficient tritium to sustain the plasma. Mixed bed solid-type breeder blankets are one possible design being investigated for use in power producing reactors. Current mixed bed designs tend to utilise a uniform mixture of neutron multiplier Be12Ti and lithium ceramic throughout the blanket. Minimizing the use of beryllium is also a priority for solid-type breeder blankets due to the scarce nature of the element. This paper investigates a method of increasing the tritium production while simultaneously reducing the quantity of beryllium required in a mixed bed breeder blanket. This is achieved by varying the multiplier to breeder ratio as a function of blanket depth. The tritium production of mixed bed blankets with an optimum uniform composition is compared to mixed bed blankets with an optimum non-uniform composition while conserving beryllium mass. The resulting increase in TBR (Tritium Breeding Ratio) when using non-uniform blankets was found to be ~1% which equates to ~1kg per year in a 3GW fusion power plant operating at 70% availability. However, the beryllium usage in non-uniform blankets is shown to be ~14% lower than uniform blankets. Hence, the benefits of achieving both reduced beryllium and increased tritium production are substantial given the associated costs of $4,500 per kg for Be12Ti and $30,000 per gram for tritium.
