The Siting Process for a Geological Disposal Facility

Essential information for Welsh communities on how to get involved


Introduction to Geological Disposal

Community Guidance for Wales


Geological disposal is one of the UK’s largest ever environmental protection projects, which will provide a safe and secure long-term solution for the disposal of higher activity radioactive waste.

We have now started the process to find a site for a Geological Disposal Facility (GDF) for radioactive waste in the UK.

In support of the Welsh Government’s policy announcement, RWM has published information for communities including:

  • Introduction to Geological Disposal - An overview into our mission to deal with radioactive waste
  • Community Guidance - How we will work with communities in Wales
  • National Geological Screening for a GDF. This provides a high level summary of the geological information which is relevant to the safety of a GDF.

To help those who may want to enter into discussions with us we have produced two Site Evaluation documents – one for Wales, and one for England.

The Site Evaluation documents have been designed to summarise, in plain and accessible terms, what we will need to consider during the siting process to ensure we can successfully investigate an area and subsequently, construct, operate and close a GDF.

We held a public consultation on how we will evaluate sites in Wales as part of our work on this important topic. This consultation has informed our final document:

The Site Evaluation – How we will evaluate sites in Wales document is also available in the Welsh Language.

Our Site Evaluation document for England is also available.

Communities will be right at the heart of the siting process for a GDF and a facility will be built where both a suitable site AND a willing community are selected.

If you want to learn more about GDF and the role of communities in the siting process, please get in touch by emailing and one of our team will get back to you.
