• Sintered UO<SUB>2</SUB> pellets irradiated at high temperature to a burnup of 2, 700 MWD/T-UO<SUB>2</SUB> were studied by replica electron microscopy. The as-irradiated pellet surfaces were covered by a thin layer easily soluble in dilute acid. This layer apparently was deposited as a sublimate during irradiation. The etched surfaces of the irradiated specimens were uniformly dispersed with flat circular domes about 1μ in diameter, constituted of precipitates resistant to etching solution, apparently a mixture of fission products and UO<SUB>2</SUB>. On the surface of each dome were several "sprout" precipitates 0.1 to 0.3μ in diameter, and almost immune to chemical etchant.
