Abstract
【解決手段】例示的な実施形態は、照射標的物質を閉じ込める端部品(120/130)を両端に有する燃料棒(100)に関する。例示的な実施形態の端部品(120/130)は、端部品(120/130)位置で遭遇する中性子線束に暴露されるときに所望の同位体に転化されうる材料を閉じ込めることができる。例示的な実施形態の端部品(120/130)は、これらの材料から製造されてもよいし、または別様にこれらの材料を収容してもよい。例示的な実施形態の端部品(120/130)は、様々な完全長燃料棒18および部分長燃料棒19と嵌り合い、かつ燃料棒(100)を上部および/または下部締結板(14/16)に嵌め合わせる上部および/または下部端栓(120/130)として機能しうる。
