The US will contribute 100% towards the disruption mitigation system (up to a capped value).
The system has two functions: 1) limiting the impacts of plasma current disruptions to the tokamak vacuum vessel, first wall blankets and other in-vessel components, and 2) suppressing the formation and deleterious effects of high energy runaway electrons. The mitigation and suppression are expected to be accomplished by rapid shattered pellet injection (SPI).
