Compatibility of Reduced Activation Ferritic/Martensitic Steels with Liquid Breeders
The compatibility of Reduced Activation Ferritic/Martensitic Steel (RAFM) with liquid Li and molten-salt Flibe have been characterized and accessed. Static compatibility tests were carried out in which the specimens were immersed into liquid Li or Flibe in isothermal autoclaves. Also carried out were compatibility tests in flowing liquid Li by thermal convection loops. In the case of liquid Li,...
متن کاملFTP1/01 Dynamic Mechanical Properties of Reduced Activation Ferritic Steels
A fatigue test method by a miniaturized hourglass-shaped fatigue specimen has been developed for International Fusion Materials Irradiation Facility (IFMIF) and sufficient potential as the alternative to a conventional large specimen was presented. Furthermore, focused ion beam micro-sampling method was successfully applied to microstructural analysis on fracture process. Where, the effects of ...
متن کاملCurrent Status of Reduced-Activation Ferritic/Martensitic Steels R&D for Fusion Energy
Reduced-activation ferritic/martensitic (RAF/M) steels have been considered to be the prime candidate for the fusion blanket structural material. The irradiation data obtained up to now indicates rather high feasibility of the steels for application to fusion reactors because of their high resistance to degradation of material performance caused by both the irradiation-induced displacement dama...
متن کاملRecent progress of R&D activities on reduced activation ferritic/martensitic steels
Several types of reduced activation ferritic/martensitic (RAFM) steel have been developed over the past 30 years in China, Europe, India, Japan, Russia and the USA for application in ITER test blanket modules (TBMs) and future fusion DEMO and power reactors. The progress has been particularly important during the past few years with evaluation of mechanical properties of these steels before and...
متن کاملHot tensile properties of 9Cr-2WVTa reduced-activation ferritic/martensitic steel
Reduced-activation ferritic/martensitic steels have been developed by replacing molybdenum by tungsten and niobium by tantalum in commercial elevated-temperature Cr–Mo steels to reduce half-life of radioactive isotopes. The objective of this study was to investigate tensile properties of a reduced-activation ferritic/martensitic steel (9Cr-2WVTa) in normalized-tempered (NT) and quenched-tempere...
