Abstract

A program was carried out to study the irradiation behavior of a PuO²-UO² fuel. Forty fuel specimens were fabricated, encapsulated, and irradiated in the General Electric Test Reactor to burnups ranging from 5000 to 99,000 Mw days per ton and heat fluxes ranging from 0.5 × 10⁶ to 1.58 × 10⁶ Btu per hr sq ft. A postirradiation examination of the fuel was made to determine the fuel condition, central void characteristics and fission gas release. The results of this program are presented and discussed.
