Operating temperature windows for fusion reactor structural materials
A critical analysis is presented of the operating temperature windows for nine candidate fusion reactor structural materials: four reduced-activation structural materials (oxide-dispersion-strengthened and ferritic/martensitic steels containing 8–12%Cr, V–4Cr–4Ti, and SiC/SiC composites), copper-base alloys (CuNiBe), tantalum-base alloys (e.g. Ta–8W–2Hf), niobium alloys (Nb–1Zr), and molybdenum...
متن کاملAccelerator-based ion beam analysis of fusion reactor materials
First wall components in controlled fusion devices undergo severe modification by various physical and chemical processes arising from plasma–material interactions: material erosion, its migration in the plasma and re-deposition. Ion beam analysis techniques play a prominent role in the studies of wall components exposed to hot plasmas. The intention of this work is to give a concise overview o...
متن کاملThe First Fusion Reactor: Iter
28 I n practical terms, the project’s goal is to construct and operate a tokamak experiment which can confine a deuterium-tritium plasma in which the α-particle heating dominates all other forms of plasma heating. Formally, the primary mission of the ITER project is to demonstrate sustainment of a DT plasma producing ~500 MW of fusion power for durations of 300 500 s with a ratio of fusion outp...
متن کاملReactor Aspects of Fusion: Issues Related to Materials, Radioactivity and Radiation-induced Effects
A concise overview is given on materials applied in fusion technology. The influence of plasma operation on the behaviour of reactor components and diagnostic systems is discussed with emphasis on effects caused by fast particles reaching the reactor wall. Issues related to primary and induced radioactivity are reviewed: tritium inventory and transmutation. Tritium breeding in the reactor blank...
متن کاملStructural materials challenges for advanced reactor systems
Key technologies for advanced nuclear systems encompass high temperature structural materials, fast neutron resistant core materials, and specific reactor and power conversion technologies (intermediate heat exchanger, turbo-machinery, high temperature electrolytic or thermo-chemical water splitting processes, etc.). The main requirements for the materials to be used in these reactor systems ar...
