| description | The present invention relates to a manufacturing method of nuclear fuel pellets with a thermal conductive metal net. The method comprises: a first step of mixing oxide nuclear fuel granule with a plate type of thermal conductive metal power whose particle size is 2-60m; a second step of molding the oxide nuclear fuel granule mixed with the thermal conductive metal power in the previous step and manufacturing a molded object; and a third step of sintering the molded object. According to the disclosed specification, the manufacturing method is capable of solving a problem associated with reducing the thermal conductivity of a pellet by using micro sized thermal conductive metal power, thereby preventing oxidization of metal substances during the process of manufacturing the pellet. In addition, by using a plate type of metal power, homogeneity of micro-structure can be improved. Therefore, the density of nuclear fuel pellets can be improved eventually, while improving the thermal conductivity as well.
본 발명은 산화물 핵연료 과립과, 입자 크기가 2 ㎛ 내지 60 ㎛이고 판상형인 열전도성 금속 분말을 혼합하는 단계(단계 1); 상기 단계 1에서 열전도성 금속 분말이 혼합된 산화물 핵연료 과립을 성형하여 성형체를 제조하는 단계(단계 2); 및 상기 단계 2의 성형체를 소결하는 단계(단계 3);를 포함하는 열전도성 금속망이 형성된 핵연료 소결체의 제조방법을 제공한다. 본 발명에 따른 핵연료 소결체의 제조방법은 마이크로 크기의 열전도성 금속 분말을 사용함으로써 소결체 제조시 발생하는 금속 물질의 산화를 방지하여 소결체의 열전도성을 감소시키는 문제를 해결하고, 판상형의 금속 분말을 사용함으로써 소결체 미세 조직의 균질성을 더욱 개선할 수 있다. 이에 따라, 궁극적으로 제조되는 핵연료 소결체의 밀도가 향상될 뿐만 아니라 열전도도가 매우 우수하다. |
