Nuclear activities worldwide generate around 200,000 m3 of radioactive waste every year. Of this about 10,000 m3, less than 5% by volume but containing most of the radioactivity, needs deep, long-term geological storage in the form of geological disposal facilities (GDFs). These caverns purpose-built hundreds of metres underground are packed with waste containers, cement backfill,…
