One would expect fusion reactor design to be concerned principally with the primary reactants and spent fuel; that is, hydrogen and helium isotopes {sup 2}D, {sup 3}T and {sup 4}He, together with {sup 7}Li used for tritium breeding. Early plasma experiments conducted in devices of small dimension were however dominated by interaction of the plasma with the walls and the release of impurity species arising from this. In large machines, it was believed such problems would be reduced, but now, even in the Joint European Torus experiment, JET, where the toroidal confinement vessel is 1-2 metres in minor radius, it has become evident that impurities sourced from the vessel walls and plasma contact points hugely influence plasma behaviour. Thus, the need for cross-section data for fusion research is clearly focused on nonfuel as well as fuel species. 82 refs., 16 figs.
