Production of nuclear fuel
Description
The grain size of uranium dioxide contained in nuclear fuel pellets is increased by heating the pellets at a temperature of at least 20000C for at least four hours in atmosphere containing hydrogen and having an oxygen potential high enough to guarantee stoichiometry or hyperstoichiometry of the uranium dioxide. The oxygen potential should not exceed -50K cal per mole O2. (author)
