Abstract

A preliminary data base to assess the radiation damage resistance of some glass ceramic materials has been gathered. These are rather complex materials, both in structure and composition, but possess many of those properties required for structural, insulator applications in fusion reactor design. Property measurements were made after fast (E>0.1 MeV) neutron irradiations of ∼2.4 × 10²² n/cm² at 400°C and 550°C. The results have shown general resistance to changes in thermal expansion and most did not experience severe loss of mechanical integrity. The maximum volume expansion occurred in several of the fluorophlogopite-based glass ceramics (~3.0%). Several observations demonstrated differences between the effects of neutron and electron irradiation; irradiation conditions prototypic of projected reactor uses need be considered for optimum materials selection.
