- Abstract
An engineering comparison is made of ceramics for use as moderators and fuel dispersants in high-temperature thermal reactors with comments on auxiliary applications. It is indicated that their major usefulness is in achieving a high temperature of operation. The major disadvantages of ceramics as unclad fuel dispersants are (a) their brittle nature, which imposes additional limits on fuel element stresses, and (b) their porosity, which may necessitate design for active circuits and clean-up systems. It is suggested that ceramics have economic potential for use in gas-cooled systems, provided designs are developed which can fully utilize their thermodynamic potential and mitigate or avoid the reprocessing and fabrication problems.
