Preliminary Assessment of Cooling Water Chemistry for Fusion Power Plants

open access: yesCorrosion and Materials Degradation, 2021
The determination of the water chemistry for cooling systems of nuclear fusion plants is under debate. It should be tailored for different types of fusion reactors: either experimental, e.g., ITER, JT-60SA, and DTT, or aimed at power generation, e.g ...

Performance of the JT-60SA superconducting magnet system during integrated commissioning

open access: yesNuclear Fusion
The fully superconducting tokamak JT-60SA achieved its first plasma already during the first operational campaign (OP-1) in 2023. To obtain this result, a suitable operation procedure of magnet system, temperature and coil current control was essential ...

Gaussian process-based quasi-coherent noise suppression in magnetic confinement devices with superconductors

open access: yesNuclear Fusion, 2023
Gaussian process (GP)-based technique suppressing quasi-coherent noises, i.e. structured noises, is developed which is more effective than conventional denoising techniques such as using frequency-domain filters. Superconducting devices like KSTAR, EAST,
