Claims (4)

  1. UO2또는 UO2와 PuO2와 예를들어 SE2O3를 함유하는 분말이나, 특히 Gd2O3를 함유하는 분말과 같은 회토류산화물함유하는 염기분말혼합에 의한, 아울러 주조틀내의 분말혼합물을 최종적으로 조밀하게하고, 1500~1750℃의 온도범위에서 소결에 의한 주조틀을 압착하는 것으로서, 회토류산화물함유의 분말로서 염기분말로 혼합하게되며 눈에 보이거나 또는 소결되는 동안 형태를 유지하고 그리고 최소한의 공간층과 화학식량구조(SE0·5, U0·5)U2·00으로 형식유형의 유리격자인 분말입자로서 생산됨을 특징으로하는 산화핵 연료소결체의 제조방법.
  2. 상기 1항에 있어서, 처음분말입자상의 UO2코팅(coating)으로 회토류산화물을 함유하는 처음물질로 부터 구워짐에 의하여 생산되는 회토류산산물함유의 분말의 특성을 지닌 상기의 방법.
  3. 상기 1항에 있어서, 처음분말입자상의 UO2분말과 회토류산화물을 함유하는 처음물질의 혼합으로부터 생산되는 회토류산화물함유의 분말특성을 지닌 상기의 방법.
  4. 상기 1항에 있어서, 우라늄과 용해된 회토류 용질로부터 결합침식에 의해 생산되는 회토류산화물함유의 분말특성을 지닌 상기의 방법.
