Performance comparison between the ITER- and DEMO-like plasmas using CRONOS simulations
This work investigates plasma performance and fusion power production of the ITER- and DEMO-like plasmas using the 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 anomal...

This work investigates plasma performance and fusion power production of the ITER- and DEMO-like plasmas using
the 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 using
the NCLASS module, while the anomalous transport is calculated using a semi-empirical Mixed Bohm/gyro-Bohm model. The
boundary conditions for the transport equations are set at the top of the pedestal where the ETB forms. The pedestal height is
calculated based on the scaling law. The time evolution of plasma current, temperatures, and density profiles of the ITER and
DEMOs that include the Chinese, Japanese, Korean, Indian, and European designs, are simulated based on their engineering
designs 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 confinement
time. The highest bootstrap fraction was found in the Korean DEMO. |
