Abstract | This work investigates plasma performance and fusion power production of the ITER- and DEMO-like plasmas usingthe integrated predictive modelling code CRONOS. These plasmas are simulated in the presence of an edge transport barrier(ETB). The transport effect includes both neoclassical and anomalous contributions. The neoclassical transport is described usingthe NCLASS module, while the anomalous transport is calculated using a semi-empirical Mixed Bohm/gyro-Bohm model. Theboundary conditions for the transport equations are set at the top of the pedestal where the ETB forms. The pedestal height iscalculated based on the scaling law. The time evolution of plasma current, temperatures, and density profiles of the ITER andDEMOs that include the Chinese, Japanese, Korean, Indian, and European designs, are simulated based on their engineeringdesigns and conceptual plans. It was found that the European Model B yielded the highest temperatures and total fusion power.The ITER design generated high fusion Q, while both the ITER and Japanese DEMO yielded the longest energy confinementtime. The highest bootstrap fraction was found in the Korean DEMO. |
