In the Eurofusion DEMO Disruption Working Group, kinetic modelling of runaway electrons in DEMO disruptions has been initiated. It is important to estimate the energy distribution of electrons in a disruption, to be able to calculate heat loads on plasma facing components. This contribution outlines the plans to proceed with this task and applicable analytical estimates are reviewed. Preliminary work with shattered pellet injection disruptions and possible natural disruption scenarios using the DREAM code is also presented. ITER-like double-stage SPI scenarios [1] were qualitatively examined using a kinetically resolved hot-tail region and a fluid RE population in a pure D-T plasma, however, shattered pellet injectors are currently not planned for DEMO. The results show that the first, pure deuterium pellet must reach the magnetic core to avoid significant hot-tail generation and given the size of the device, considerably higher amounts of deuterium are needed than is predicted for ITER [1]. DEMO plasmas will have a higher effective charge than ITER due to the high-Z impurities deliberately added to allow for a high radiated power fraction. However, this means there is a possibility that a strong temperature instability can occur already at the start of a disruption. Some preliminary natural disruption results are shown.
