    New tungsten alloy: potential material for fusion reactors. The ITER International School aims to prepare young scientists/engineers for work in the field of nuclear fusion and in research applications associated with the ITER Project. is the development of excellence in research in fusion science and technology within the ITER framework. Vanadium alloys exhibit important advantages as a candidate structural material for fusion first-wall/blanket applications. These advantages include high temperature and high wall load capability, favorable safety and environmental features, resistance to irradiation damage, and alloys of interest are readily fabricable. A substantial data base has been developed on laboratory-scale heats of V Cited by:

      The indicator radionuclide31Si produced in neutron and deuteron activation analysis for silicon via the reactions30Si(n,γ) and30Si(d,p), respectively, is specifically separated from the irradiated sample by distillation as31SiF4. In the case of aluminium, the distillation is carried out from a HF(HNO3)H2O2 medium and in the case of molybdenum, niobium, tantalum, titanium and vanadium Cited by: 9. vanadium alloy (vcr-5ti) Vanadium-based alloys are considered promising candidate structural materials for fusion in-vessel first wall and blanket applications. Although the data base is limited compared to other leading candidate structural materials, such as austenitic and martensitic steels, vanadium-based alloys exhibit several.

      The working conditions are considered for pin sheath materials for future fast-neutron reactors, as well as the scope for using various classes of material for the sheaths. Alloys of vanadium with titanium and chromium are found to have advantages for these by: 9. Development of reduced-activation martensitic 9Cr steels for fusion reactor.
