Industry supported improved design of DEMO BoP for HCPB BB concept with energy storage system

Abstract The EU Demonstration Fusion Reactor (DEMO) Balance of Plant (BoP) configuration studied consists of the Primary Heat Transfer System (PHTS), the Intermediate Heat Transfer System (IHTS), using HITEC salt as coolant, equipped with a thermal Energy Storage System (ESS), and the Power Conversion System (PCS). This configuration is capable of producing electricity continuously through the pulse time (2 h), as well as dwell time (10 min) of the plant operation. The DEMO BoP development process was supported by industrial partners: Siemens Power and Gas Division and Kraftanlagen Heidelberg (KAH). The efficiency of the proposed Rankine cycle of the PCS is obtained to be not less than 39%. While elaborating the improved DEMO BoP design, KIT developed a plant model using the industrial code EBSILON ® .
