PROCESS is a systems code at UKAEA that calculates in a self-consistent manner the parameters of a fusion power plant with a specified performance, ensuring that its operating limits are not violated, and with the option to optimise to a given function of these parameters.
Menard et al. (2016) proposes for an spherical tokamak a relation between elongation and internal inductance:
This can be implemented under the
iprofile
switch.
