Steady-state engineering test reactors (ETRs) with high-field, low-current operation are investigated and compared to high-current lower field concepts. For similar wall loading it is shown that the fusion power of an illustrative high-field, low-current concept could be about 50% that of a lower field device like TIBER II. This reduction could lead to a 50% decrease in tritium consumption, resulting in a substantial decrease in operating cost. Furthermore, high-field operation could lead to substantially reduced current drive requirements and cost. Further savings would be attained from the reduced size of the first wall/blanket/shield system. The effects of high fields on magnet costs are very dependent on technological assumptions. Future improvements may lie with advances in superconducting and structural materials.
