Behavior of Carbon During the Synthesis of Mixed Nitrides of Uranium and Plutonium

Аннотация

The behavior of carbon in reactions of the synthesis of mixed nitrides of uranium and plutonium is determined not only by its excess content against stoichiometry, but also by the active influence of hydrogen and nitrogen as components of technological gas. It is also necessary to account for the impact of products of thermolysis of the binder. The results of a thermodynamic analysis of possible reactions during synthesis indicate the special behavior of phase UC_1.91 in the process and bring up additional questions on the mechanism of removal of excess carbon under temperatures of synthesis.
