Methods and costs of fabrication in relation to performance of beryllia in an HTGC reactor

Abstract

The decision to use beryllia in a reactor requires a balance between cost and performance in the light of a continually developing technology and reducing costs of raw materials. This paper attempts to summarise some of the properties of beryllia most pertinent to high temperature gas-cooled reactor design and to discuss the relative advantages in improving these properties; the fabrication processes are discussed whereby improved properties are most likely to be attained at minimum cost.
