Development of the plasma technology for the production of uranium oxides with a given oxygen coefficient for the fabrication of pelletized nuclear fuel
Tóm tắt
The process of uranium reduction via plasma denitration of uranyl nitrate solutions in a plasma reactor of a nuclear-safe geometry with the use of soluble reducing agents (carbamide (NH2)2CO, sucrose C12H22O11, and acetic acid CH3COOH) is studied. Dispersed uranium oxide with the required oxygen coefficient (2.1–2.3) is obtained. It is found that acetic acid is the optimum reducing agent, and the optimum mass ratio HAc/U is 0.5–0.6. It is demonstrated that the synthesis of uranium oxides by the plasma denitration method is economically more viable than the mainstream technology.
