The Power Burst Facility (PBF) is a flexible, pulse‐type nuclear reactor constructed to provide high thermal neutron fluxes during short period power excursions. The PBF reactor core is composed of a fuel in the system UO 2 ‐ZrO 2 CaO. The performance requirements imposed on this fuel necessitated a testing program to establish out‐of‐pile and in‐pile characteristics of the fuel. This paper presents some of the in‐pile test results obtained under pulse conditions, and out‐of‐pile results on selected fuel compositions to verify phase and volume stability of the ternary fuel. Compositions of 16 and 35 mol% urania were investigated from 2000° to 2700°C in‐pile.
