Abstract
Heats of immersion of U02 powders in water were d etermined
by calorimetric m easurements. The integral heat of immersion
at 25°C was found to be 490 erg/ cm2 with a n uncertainty± 70/o for
stoichiometric U02. The value is linearly increasing with increasing
non-stoichiometry of the powders up to 790 erg/cm!± 7° / o for U30 8•
The result is not influenc ed by different p a rticle size distribution,
obtained by some different me thods of synthesis of U02 powders.
