Systems codes are used in the conceptual phases of fusion reactors design. They employ a
multitude of simplified models to simulate an entire power plant and ensure that designs are
self-consistent, viable and optimised with respect to a given figure of merit. Their strength is
the fast determination of an overall design. However, their output should be viewed with
caution due to model simplicity and requires verification via more detailed physics and
engineering analysis.
The PROCESS systems code is predominantly used to model the European
demonstration power plant, DEMO. As such, it is under constant development to improve its
capabilities. In this work, we describe the integration of a simple, 1D transport and equilibrium
model known as PLASMOD [1] into PROCESS. This represents a significant step up in
physical realism with the creation of self-consistent radial profiles including electron density
and temperature.
PLASMOD is a time-independent transport model combined with an equilibrium solver
from ASTRA. It has been benchmarked against both a standalone version of ASTRA and
running within PROCESS. We present initial results from PLASMOD integrated with
PROCESS, highlighting the impact on the calculated power plant design and performance of
the newly implemented transport model.
