Abstract:
The design features developed for the
Spherical Tokamak (ST) in the PPPL pilot plant study was
used as the starting point in developing designs to meet the
mission of a Fusion Nuclear Science Facility (FNSF)
considering a range of machine sizes based on the influence
of tritium consumption and maintenance strategies. The
compact nature of a steady state operated ST device for this
mission pushes operating conditions and places challenges
in the design of components, device maintenance and the
integration of supports and services.
This paper reviews the general arrangement, design
details and maintenance strategy of the ST-FNSF device
core for a 1.6-m and 1.0-m device; operating points which
bracket the region between purchasing and breeding tritium.
