DEMO fusion power reactor features multiple different grade heat sources, like the first wall and blanket, divertor, and vacuum vessel. The way of using these sources and their compatibility with the power conversion cycle will affect the efficiency of electricity production. A significant complication is a pulse operation of the fusion reactor unless the noninductive generation of the plasma electric current is developed. In this case, an energy storage application is necessary for conventional electricity production. This article is focused on the supercritical CO2 power conversion Brayton cycle and on optimization of selected S-CO2 layouts with the integrated energy storage. The purpose is to compare the efficiency of selected cycle layouts and to find the highest efficiency layout with the multiple different grade heat sources and energy storage.
