Abstract:
A fusion pilot plant study was initiated to clarify the development needs in moving from ITER to a first
of a kind fusion power plant. The mission of the pilot plant was set to encompass component test and fusion nuclear
science missions yet produce net electricity with high availability in a device designed to be prototypical of the
commercial device. The objective of the study was to evaluate three different magnetic configuration options, the
advanced tokamak (AT), spherical tokamak (ST) and compact stellarator (CS) in an effort to establish component
characteristics, maintenance features and the general arrangement of each candidate device. With the move to look
beyond ITER the fusion community is now beginning to embark on DEMO reactor studies with an emphasis on
defining configuration arrangements that can meet a high availability goal. This paper reviews the AT pilot plant
design, detailing the selected maintenance approach, the device arrangement and sizing of the in-vessel components.
Details of interfacing auxiliary systems and services that impact the ability to achieve high availability operations
will also be discussed.
