Qualification of Structural Materials for Reactor Systems: Synergies in Materials for Fusion/Fission Reactors and Advanced Fission Reactors

摘要

In nuclear technology a lot of experience has been accumulated meanwhile from reactor programmes for ferritic alloys, austenitic steels and Ni-based alloys as main component materials during R&D, design, construction and operation. Generally materials are a key issue for a safe and reliable operation of NPPs. Many grades investigated are of interest for the design of GenIVs and fusion reactors.rnSynergisms of materials, material technologies, mechanical data, corrosion and other topics for the qualification of materials for nuclear systems are generally discussed and information on a qualification procedure is compiled. Also some lessons learned from fabrication, test programmes or operation of NPPs are provided. A special problem is the fusion system because a final validation for alloy performance in the long term will need irradiation under realistic fusion condition anticipated in a high-energetic, fusion-specific intense neutron source such as (IFMIF), the International Fusion Materials Irradiation Facility.
