A fusion development facility on the critical path to fusion energy...

A fusion development facility (FDF) based on the tokamak approach with normal conducting magnetic field coils
is presented. FDF is envisioned as a facility with the dual objective of carrying forward advanced tokamak (AT)
physics and enabling the development of fusion energy applications. AT physics enables the design of a compact
steady-state machine of moderate gain that can provide the neutron fluence required for FDF’s nuclear science
development objective. A compact device offers a uniquely viable path for research and development in closing the
fusion fuel cycle because of the demand to consume only a moderate quantity of the limited supply of tritium fuel
before the technology is in hand for breeding tritium.
