One possible route for the geological disposal of the Belgian reactor 1 (BR1) fuel, which will eventually become nuclear waste, could be the direct encapsulation of the whole fuel capsule in a cementitious matrix. Because the cladding of the BR1 fuel is made of aluminium alloy 1100 (AA1100), this alloy would be in direct contact with the cementitious matrix. Due to its amphoteric property, aluminium cannot form a passive corrosion product film in Ordinary Portland Cement (OPC) paste, which possesses a highly alkaline condition.
