Updated reference liquid-metal-cooled tandem mirror fusion breeder design

This paper summarizes the current version of a reference design for a liquid-metal-cooled tandem mirror fusion breeder (fusion-fission hybrid reactor). The design update incorporates the results of several recent studies that have attempted to resolve key technical issues associated with an earlier reference design completed in 1982. The issues that were addressed relate to the following areas of design and performance: nuclear performance, magnetohydrodynamic (MHD) pressure loading, beryllium multiplier lifetime, structural efficiency and lifetime, reactor safety, corrosion/mass transfer, and fusion breeder capital cost
