TL;DR: In this paper, a brief overview on the disruption loads and mitigation strategies for ITER and the physics basis which is continuously refined through the current disruption R&D programs is discussed.

TL;DR: In this paper, the impact on confinement and power load of a high-shape 2.5MA ELMy H-mode scenario at JET with a change from an all carbon plasma facing components to an all metal wall was investigated.

Abstract: This paper reports the impact on confinement and power load of the high-shape 2.5 MA ELMy H-mode scenario at JET of a change from all carbon plasma-facing components to an all metal wall. In preparation to this change, systematic studies of power load reduction and impact on confinement as a result of fuelling in combination with nitrogen seeding were carried out in JET-C and are compared with their counterpart in JET with a metallic wall. An unexpected and significant change is reported on the decrease in the pedestal confinement but is partially recovered with the injection of nitrogen.

TL;DR: In this paper, the authors report the progress made at JET-ILW on integrating the requirements of the reference ITER baseline scenario with normalized confinement factor of 1, at a normalized pressure of 1.8 together with partially detached divertor whilst maintaining these conditions over many energy confinement times.

TL;DR: De Vries et al. as discussed by the authors conducted a survey to identify the root causes, the chain-of-events and classifying each disruption, similar to a previous analysis for carbon-wall operations.
