摘要： A method of making a nuclear fuel structure may include reducing a metal oxide in a cathode assembly so as to deposit a metal of the metal oxide on the cathode plate of the cathode assembly, and processing the cathode plate with the metal deposited thereon to fabricate the nuclear fuel structure. The cathode plate may include an upper blade including an electrically conductive material, a lower blade portion connected to the upper blade, and a connection structure configured to secure the lower blade portion to the upper blade while providing electrical continuity. The connection structure may be configured to be disconnected from the lower blade portion to detach the lower blade portion from the upper blade.

摘要： The method concerns processing irradiated (spent) nuclear fuel (SNF), is primarily aimed at isolating and trapping tritium, and can be used in nuclear power industry for treating SNF.
This method provides for the breakage of SNF elements comprising uranium dioxide into fragmented reaction mass and a two-phase voloxidation of the reaction mass using gas-air mixture. The first phase is carried out at 400-650°C in the presence of air and carbon dioxide. The second phase is carried out at 350-450°C using air-vapor mixture. Both phases are carried out at a continuous or periodic mechanical activation of the reaction mass. In the course of the voloxidation, the gas flow rate provides for 10-50-fold change of the reaction chamber gas volume per hour, and before being introduced into the reaction chamber, the gas is heated up to the chamber temperature at the respective phase.
