“…First, reference plasma parameters for hybrid scenarios and steady-state scenarios have been proposed based on calculations using the 0-D system code GASC, 71 and, subsequently, systematic studies using PROCESS 72 showed that there was a reasonable number of feasible operating scenarios for a CFETR with a high fusion power. 70 , 73 Two-dimensional free boundary equilibrium calculations were then performed to design the plasma shape, which showed that the conventional single null divertor (SND) configuration could be sustained by the PF coils. 74 Compatibility of this SND configuration, along with the power exhaust requirement, was demonstrated through SOLPS simulations.…”

“…This work applies the same tool to the 2017 European baseline design [1] and extends the scope of the work to a more complete set of uncertainties (including engineering parameters). Other work applying a similar technique to the Chinese CFETR design has been carried out by Morris et al [8] and work on the Indian SST-2 design by Muldrew et al [9].…”

“…In this section, we summarise a selection of known uncertainties in extrapolating the plasma conditions (section 3.1) as well as technological parameters (section 3.2) to fusion power plants. The lists describe the relevant quantity and the assumed uncertainty distributions 8 . Where possible this has been motivated with appropriate references.…”

During the pre-conceptual design phase of fusion devices such as the European demonstration fusion power plant (DEMO), systems codes provide a fast evaluation of optimal design points and highlight high impact areas. However, determining or evaluating a design point at such an early stage comes with uncertainties in many of the design parameters. These uncertainties are both associated with the physics as well as the engineering basis of the European DEMO design. The work applies an uncertainty quantification analysis to the 2017 pulsed European DEMO design using the PROCESS systems code. It assumes that DEMO will be built as suggested by the baseline and explores what implications the currently known physics and engineering uncertainties have on the expected performance parameters (net electric output and pulse length), while optimising the fusion gain Q. A more detailed single parameter analysis is clearly identifying high impact parameters. This is confirming previous investigations as well as revealing new areas that warrant deeper investigation in particular in the technology area.

“…As the power plant design programmes approach the transition between the pre-conceptual and conceptual design phases, the use case for systems codes requires that they offer more detailed insight into the plant systems. The systems code PROCESS [1,2] has been in active development at UKAEA for over 20 years and has been used heavily in the EUROfusion DEMO programme [3][4][5][6] as well as other reactor projects such as CFETR [7] and STEP [8]. The systems code PROCESS has been improved to incorporate more detailed plasma physics, engineering, and integration models.…”

As power plant design programmes approach the transition between the pre-conceptual and conceptual design phases, the systems code PROCESS has been improved to incorporate more detailed plasma physics, engineering, and analysis modules. Unlike many systems codes, PROCESS combines the physics modelling with both technology and costs analysis. Some of the key topics in the conceptual design phase are toroidal field (TF) magnet design, divertor power handling, operational sensitivity, and economic uncertainty analysis. Models covering these areas have been integrated or improved in PROCESS. During pre-conceptual design, systems codes are an essential tool for exploring fusion power plant concepts. They allow one to model the interaction of the plant systems and quickly perform reactor optioneering. To be able to carry out these large scoping studies, the fidelity of the models can be restricted to reduce the computational time. For example, the EUROfusion EU-DEMO baseline designs are created using the systems code PROCESS and the ability to measure these trade-offs has led to important design choices being examined during the DEMO pre-conceptual design phase. Ruling out unfeasible designs allows one to efficiently identify where in the design space to carry out detailed design work. The paper describes how PROCESS has begun retooling for use in later stages of power plant conceptual design. Details are given for new additions to the PROCESS uncertainty quantification tools, high-temperature superconducting magnet model, TF coil model, and new models for spherical tokamaks (STEP). Additionally, the paper covers recent developments on the novel systems code BLUEPRINT, which is being used in both the EUROfusion and STEP projects. The paper concludes with an outlook on systems code activities at UKAEA and work with external partners.
