Abstract

The status of research and development on vanadium alloys and on their application as a structural material in the breeder blanket of a fusion power plant are reviewed. Emphasis has been placed on irradiation experiments and the effects of neutron and ion irradiation on the microstructure of the current reference alloy, V4Cr4Ti. The effects of a liquid lithium environment and the exchange of carbon, nitrogen, and oxygen impurities between the alloy and application-relevant environments are also reviewed. The dependence of microstructural features on irradiation experiment parameters are examined, with a summary on magnetohydrodynamic effects and mechanical properties of the alloy. The relationship between the ductility and the alloy chemistry and the irradiation test temperature are analysed. Review of the state of the art indicates that further developments of facilities simulating a realistic fusion radiation and liquid lithium environment are fundamental to advancing fusion reactor breeder design.

期刊介绍： The journal accepts papers about experiments (both plasma and technology), theory, models, methods, and designs in areas relating to technology, engineering, and applied science aspects of magnetic and inertial fusion energy. Specific areas of interest include: MFE and IFE design studies for experiments and reactors; fusion nuclear technologies and materials, including blankets and shields; analysis of reactor plasmas; plasma heating, fuelling, and vacuum systems; drivers, targets, and special technologies for IFE, controls and diagnostics; fuel cycle analysis and tritium reprocessing and handling; operations and remote maintenance of reactors; safety, decommissioning, and waste management; economic and environmental analysis of components and systems.
