西班牙乏燃料地质处置罐设计中的一个关键问题是选择钢壁与燃料组件之间的内衬材料。这种材料必须主要避免一旦罐被腐蚀破坏并被地下水淹没而发生临界事件的可能性。本文设计并提出了一套详细的材料要求，以满足在该环境中的这一作用。考虑到这些要求，评估了八种可能感兴趣的候选材料：铸铁或钢、硼硅酸盐玻璃、尖晶石、贫化铀、脱水沸石、赤铁矿、磷酸盐和橄榄石。其中，前四种材料或它们的家族被发现有希望用于该应用。
One of the key aspects in designing Spanish spent nuclear fuel canister for geological repository is selecting the inner material to be placed between the steel walls and the fuel assemblies. This material has to primarily avoid the possibility of a criticality event once the canister gets breached by corrosion and flooded by groundwater. A detailed set of requirements for a material to fulfil this role in that environment have been devised and presented in this paper. With these requirements in view, eight potentially interesting candidates were evaluated: cast iron or steel, borosilicate glass, spinel, depleted uranium, dehydrated zeolites, haematite, phosphates, and olivine. Among these, the first four materials or their families are found promising for this application.
