Tungsten-based compounds are prized for exceptional properties crucial in nuclear fusion applications. Commonly cemented carbides can not be used in nuclear fusion applications due to the environmental, nuclear and high temperature limitations of cobalt and its alloys. This work proposes the use of small additions of low activation metals as alt…
During development of the UKAEA’S Spherical Tokamak for Energy Production (STEP), assessment of manufacturing strategies for the inboard shield identified several gaps in knowledge. Limits arose from the modularization of this component, geometric constraints of tungsten ceramic forming, joining with low-activation interlayers and dissimilar j…
This Review considers current Zr alloys and opportunities for advanced zirconium alloys to meet the demands of a structural material in fusion reactors. Zr based materials in the breeder blanket offer the potential to increase the tritium breeding ratio above that of Fe, Si and V based materials. Current commercial Zr alloys might be considered …
