Materials research is recognized as a key to the development of an economic and reliable fusion reactor. The environment in which materials must perform in a magnetic fusion reactor is established and general criteria for selecting structural and special purpose materials are summarized. On this basis, the U.S. program in materials development for fusion is described. Key program elements include the development of alloys for use as structural materials, the study of fundamental processes central to radiation damage analysis, the development of special purpose materials, the study of plasma materials interactions, the development of coatings and special material surfaces, and the development of components capable of handling high heat and particle fluxes that are incident on components like limiters, divertor target plates, neutral beam heat dumps, and other in-vessel components in fusion reactors. The relationship of the materials program to the rest of the national fusion program is discussed.

Materials for a fusion reactor first wall and blanket structure must be able to reliably function in an extreme environment that includes 10-15 MW-year/m2 neutron and heat fluences. The various materials and structural challenges are as difficult and important as achieving a burning plasma. Overcoming radiation damage degradation is the rate-controlling step in fusion materials development. Recent advances with oxide dispersion strengthened ferritic steels show promise in meeting reactor requirements, while multi-timescale atomistic simulations of defect-grain boundary interactions in model copper systems reveal surprising self-annealing phenomenon. While these results are promising, simultaneous evaluation of radiation effects displacement damage (≤ 200 dpa) and in-situ He generation (≤ 2000 appm) at prototypical reactor temperatures and chemical environments is still required. There is currently no experimental facility in the U.S. that can meet these requirements for macroscopic samples. The E.U. and U.S. fusion communities have recently concluded that a fusion-relevant, high-flux neutron source for accelerated characterization of the effects of radiation damage to materials is a top priority for the next decade. Data from this source will be needed to validate designs for the multi-$B next-generation fusion facilities such as the CTF, ETF, and DEMO, that are envisioned to follow ITER and NIF.

Fusion materials development is one of four key technical issues identified in the U.S. Magnetic Fusion Program Plan. A long-range program has been formulated recently to provide the scientific and technological basis for assessing the economic and environmental viability of fusion power. An increasingly important element is international participation. The major emphasis is currently on the development of low activation structural materials. The program must also be prepared to meet the near-term needs of the Compact Ignition Tokamak and the proposed International Thermonuclear Experimental Reactor. To do so, the effort on non-structural materials is expected to increase.

The Fusion Materials Irradiation Test Facility (FMIT) is a high-energy, high-flux neutron source for fusion materials development. The FMIT linear accelerator will produce a 35 MeV beam of deuterons that generates high-energy neutrons by a nuclear stripping reaction with flowing liquid lithium targets. The targets will be located in two identical irradiation test cells, either of which will provide an irradiation volume of 10 cm3 at a neutron flux of 1015 n/cm2-s and 500 cm3 at a flux of 1014 n/cm2-s. FMIT has been authorized by the US Congress and will be constructed and operated by the Hanford Engineering Development Laboratory (HEDL) at Richland, Washington, in collaboration with the Los Alamos Scientific Laboratory (LASL) which is providing the accelerator design. The project is currently entering the detailed design phase, targeting for start of construction in early 1980 and operaion in 1983-84. Research and development programs are underway at both HEDL and LASL to resolve uncertainties in the lithium target and accelerator designs.

The realization of fusion energy is a formidable challenge with significant achievements resulting from close integration of the plasma physics and applied technology disciplines. Presently, the most significant technological challenge for the near-term experiments such as ITER, and next generation fusion power systems, is the inability of current materials and components to withstand the harsh fusion nuclear environment. The overarching goal of the ORNL fusion materials program is to provide the applied materials science support and understanding to underpin the ongoing DOE Office of Science fusion energy program while developing materials for fusion power systems. In doing so the program continues to be integrated both with the larger U.S. and international fusion materials communities, and with the international fusion design and technology communities.
