Abstract
The GasOff project studied gas generation from low-level radioactive waste at TVO’s Olkiluoto disposal facility over 26 years. Sixteen steel drums containing cellulose-based materials were monitored under simulated repository conditions. Results showed gas production, mainly methane and carbon dioxide from microbial activity. Microbial communities contributed to both gas generation and steel corrosion. Concrete containers maintained structural integrity, though some surface changes were observed. The experiment provides valuable data for future safety assessments and long-term management of radioactive waste repositories.
