TE’s iterative workflow allows for early and rapid experimentation with machine design points. The starting point is PyTOK, an in-house whole plant systems code, which finds optimal design points across a range of parameters, whilst enforcing engineering self-consistency. A favourable design is taken into a rapid engineering and physics workflow, where the team assesses it more in-depth for up to two weeks. The assessments include neutronics for nuclear heating and tritium breeding ratio, initial plasma scenario and operating point analyses, magnet cage optimisation and plasma exhaust checks. By involving the entire team at this early stage, and not fully relying on an integrated code to analyse the design points, we ensure that an integrated and coherent device is carried forward to the next level of fidelity.
