The invention relates to a method for chemically stabilizing a uranium carbide compound having the formula UCx + yC, where x = 1 or 2, and y > 0, x and y being real numbers, placed in a stabilization chamber, characterized in that it includes the following steps: a step of raising the internal temperature of said chamber to a so-called oxidization temperature for oxidizing said uranium carbide compound, which is between around 380°C and 550°C, said chamber being supplied with an inert gas; a step of isothermal oxidization treatment at said oxidization temperature, said chamber being placed under partial pressure of O2; and a step of checking for the completion of the stabilization of said compound, said step including tracking the amount of consumed dioxygen, and/or carbon dioxide, or carbon dioxide and carbon monoxide released until an input set value for said amount of dioxygen, a minimum threshold value for said amount of carbon dioxide, or minimum threshold values for the carbon dioxide and carbon monoxide, are reached. The invention also relates to a device for implementing the method. |
