Great projects are carried out in collaboration:
HLW Repository for UK, United Kingdom
In 2017-2018 AINS and Atkins supported RWM in developing a costed, logic linked technical programme that defined the technical development and de-risked activities required for the geological disposal facility GDF. AINS provided first-hand experience and support from their numerous repository programmes e.g. cost estimation, benchmarking, scheduling, technical development input, public communication strategy, EIA, safety analyse, rock classification, facilities, site selection, regulatory involvement, transitional organisations, requirement management and stepwise implementation.
- Disposal of high level waste (HLW)
- Possible both HLW and LILW to the same facility
- 200-1000 metres deep, the area several square km
- A national geological screening was started in 2015
“Thank you for taking the time to travel to the RWM offices last week, the presentations were very informative.”
