NUCLEAR-DATA NEEDS FOR LOW-ACTIVATION FUSION MATERIALS DEVELOPMENT

So-called "low-activation" materials are presently considered as an important means of improving the safety and environmental characteristics of future DT fusion reactors. Essential benefits are expected in various problem areas ranging from operation considerations to aspects of decommissioning and waste disposal. Present programs on "low-activation" materials development depend strongly on reliable activity calculations for a wide range of technologically important materials. The related nuclear data requirements and important needs for more and improved nuclear data are discussed. © 1990.
