Tokamak systems analyses using a fast 1D transport solver: models and assessments

During the pre-conceptual design stage of nuclear fusion power plants, systems codes provide rapid evaluation of feasible design points and consequences of major design choices. They do this by optimizing simple models of all relevant power plant subsystems within physical laws and engineering limits. Typically these models use 0D scaling relations to describe the interactions between the physics and engineering design parameters. This can lead to oversimplifications due to the high non-linearity of the underlying physics models involved.
