abstract = {Although the ultimate goal of most current fusion research
is to build an economically attractive power plant, the
present status of physics and technology does not provide
the performance necessary to achieve this goal. Therefore,
in order to model how such plants may operate and what their
output might be, extrapolations must be made from existing
experimental data and technology. However, the expected
performance of a plant built to the operating point
specifications can only ever be a 'best guess'.
Extrapolations far beyond the current operating regimes are
necessarily uncertain, and some important interactions, for
example the coupling of conducted power from the scape-off
layer to the divertor surface, lack reliable predictive
models. This means both that the demands on plant systems at
the target operating point can vary significantly from the
nominal value, and that the overall plant performance may
potentially fall short of design targets.In this
contribution we discuss tools and techniques that have been
developed to assess the robustness of the operating points
for the EU-DEMO tokamak-based demonstration power plant, and
the consequences for its design. The aim is to make explicit
the design choices and areas where improved modelling and
DEMO-relevant experiments will have the greatest impact on
confidence in a successful DEMO design},
