Studies for a fusion Technology Development Facility

Abstract

We have been studying small, driven fusion reactors as candidates for a Technology Development Facility (TDF) to be used for testing reactor subsystems, components, and materials. Magnetic mirror systems are particularly interesting for this application because of their inherent steady-state operation, potentially high wall loading, and relatively small size. The systems so far studied have 14-MeV neutron wall loads ranging from 1 to 3 MW m/sup -2/ on testing surface areas of 2 to 5 m/sup 2/ with annual fluences as high as 10/sup 21/ neutrons cm/sup -2/. These devices are based on physics and engineering that has been demonstrated or is scheduled for demonstration in the next year
