Geological Disposal Facility (GDF) Siting Process UK
UK (siting process ongoing) · Siting process began 2018, construction many years away (first permit application expected ~2028) · Multi-billion pound project (estimated £12bn for construction and operation over its lifetime)
The judgement call
Account-gated at launchThe UK policy is to dispose of higher activity radioactive wastes permanently in a deep geological repository. - The siting process is community-led, emphasizing voluntary participation and local consent. - The project is one of the UK's most important environmental undertakings, addressing a legacy of radioactive waste. - The long timescale for development and operation (hundreds of thousands of years) presents unique intergenerational challenges.
Key engineering challenges
Identifying a geologically suitable site with a willing community, a complex socio-technical challenge. - Designing a facility that can safely contain radioactive waste for hundreds of thousands of years. - Developing robust safety cases and demonstrating long-term environmental protection. - Managing public engagement and building trust in the siting and development process.
