ZrO2-based gadolinium-containing burnable poison material and preparation method thereof, burnable poison pellet and burnable poison rod
The invention discloses a ZrO2-based gadolinium-containing burnable poison material, which comprises ZrO2, Gd2O3 and Y2O3, the content X of Gd2O3 is more than or equal to 0.1 mol% and less than or equal to 3mol%, the content Y of Y2O3 is more than or equal to 3mol% and less than or equal to 7mol%, and the balance is ZrO2. The invention also discloses a preparation method of the ZrO2-based gadolinium-containing burnable poison material, a burnable poison pellet formed by processing the ZrO2-based gadolinium-containing burnable poison material, and a burnable poison rod comprising the burnable poison pellet. The ZrO2-based gadolinium-containing burnable poison material disclosed by the invention is relatively low in monoclinic phase content at normal temperature, can be stabilized in a highly symmetrical cubic phase structure, and is good in mechanical property and high in structural stability.
本发明公开一种ZrO2基含钆可燃毒物材料，其组分包括ZrO2、Gd2O3、以及Y2O3，其中，Gd2O3的含量X为0.1mol％≤X≤3mol％，Y2O3的含量Y为3mol％≤Y≤7mol％，其余为ZrO2。本发明还公开一种ZrO2基含钆可燃毒物材料的制备方法，以及采用上述ZrO2基含钆可燃毒物材料加工而成的可燃毒物芯块、包括上述可燃毒物芯块的可燃毒物棒。本发明的ZrO2基含钆可燃毒物材料在常温下的单斜相含量较低，可稳定在高对称的立方相结构，力学性能好，结构稳定性高。
