| Abstract Scope |
The Nuclear Technology R&D program is investigating improved fuels for advanced reactors. These new fuels and cladding materials must be developed and tested to high burnup levels (e.g. >20%) requiring cladding to withstand very high doses (greater than 200 dpa) while in contact with the coolant and the fuel. New ferritic/martensitic and ferritic Oxide Dispersion Strengthened (ODS) alloys are being developed with improved radiation tolerance. These advanced materials are being produced through powder-based techniques. Ferritic/martensitic (F/M) steels (e.g. grade 91) are being produced through additive manufacturing (AM) while ferritic ODS alloys are being processed through powder metallurgy (PM) techniques. The AM produced F/M steels show very high strength up to 650C while maintaining excellent ductility while the ferritic ODS steels show good high temperature strength and excellent radiation tolerance. Recent progress in these two new alloys will be presented. |
