Abstract: 

The standard high performance operational scenarios in tokamak fusion reactors are based on a formation of an edge transport barrier and pressure pedestal at the edge of the plasma. This pedestal region must enable sufficiently high overall fusion performance, while also accommodating the necessary power exhaust measures to avoid overheating of the reactor components. However, due to the multiple relevant physical processes, and spatiotemporal scales, predicting pedestals is very challenging, and an all-encompassing, high-fidelity
