  1. 一種用於安裝一燃料總成於一核子反應器中之總成，其包括：一燃料總成，其包括處於該燃料總成內之燃料桿，該燃料總成包括一具有在該燃料總成之一底部上之一燃料總成配合夾具之下部繫板；及一燃料支架，其包括一燃料支架配合夾具，該燃料支架配合夾具及該燃料總成配合夾具係成形為使該二者在該燃料總成相對於該燃料支架之唯一、唯二或唯三方向上可彼此插入配合；其中形成該燃料總成之該底部之該燃料總成配合夾具，其係經構造以在該燃料總成被直立地下降進入該燃料支架時，對準且配合該燃料支架配合夾具。
  2. 如請求項1之總成，其中該燃料支架經組態以抬高該燃料總成，除非該燃料總成配合夾具於該唯一、唯二或唯三方向上與該燃料支架配合夾具嚙合。
  3. 如請求項1之總成，其中該燃料總成配合夾具係在該燃料總成配合夾具相對於該燃料總成內之該等燃料桿之該唯一、唯二或唯三方向其中之一上，自一由該燃料總成所界定之軸線以一徑向為中心定位。
  4. 如請求項3之總成，其中該燃料支架配合夾具係由該燃料支架之一本體之一部份所構成，其界定一開孔以接納該下部繫板。
  5. 如請求項1之總成，其中該燃料總成配合夾具包括該下部繫板之一外部形狀，以提供該燃料總成與其中所包含之柵格之該唯一、唯二或唯三方向，且其中該燃料支架配合夾具包括一由該燃料支架所界定之呈一對應形狀之開孔，該開孔用於在將該燃料總成安裝至該燃料支架上時接納該下部繫板並保持該燃料總成與該燃料支架之該唯一、唯二或唯三方向。
  6. 如請求項5之總成，其中該下部繫板之該外部形狀及該開孔之該對應形狀係選自由一三角形、一四角形、一五角形、一七角形及一星形組成之群組。
  7. 如請求項1之總成，其中該燃料總成配合夾具包括一凸形構件，且其中該燃料支架配合夾具包括一經組態以接納並緊固該凸形構件以達成該唯一、唯二或唯三方向之凹形構件。
  8. 如請求項7之總成，其中該凹形構件包括一斜面空腔，該斜面空腔用於將該下部繫板引導至該空腔中並適當地將該燃料總成配合夾具與該燃料支架配合夾具配合。
  9. 如請求項1之總成，其中該燃料支架配合夾具包括一凸形構件，且其中該燃料總成配合夾具包括一經組態以接納並緊固該凸形構件以提供該唯一、唯二或唯三方向之凹形構件。
  10. 如請求項1之總成，其中定位於該燃料總成內之該等燃料桿係配置成具有在該燃料總成內之該唯一、唯二或唯三方向之一預定圖案。
