Probabilistic corrosion analysis for secure long-term geological disposal of nuclear waste in high-chloride environments

Geological Disposal Facilities (GDFs) are deemed the safest option for nuclear waste disposal, employing a system of natural and engineered barriers for secure storage. Crucial to this process are robust containers manufactured from materials such as stainless or carbon steel, shielded by backfill materials consisting of cement or clay at depths reaching hundreds of meters into rock. Preserving these containers for thousands of years requires a clear understanding of corrosion rates, corrosion product formation, and gas generation, particularly in high-chloride aqueous environments; a vital yet understudied aspect relevant to the UK’s GDF program.
