FAQ: Near-surface Disposal Facilities on Land for Solid Radioactive Wastes; Guidance on Requirements for Authorisation

Why has the guidance been published now?

In 1997, the environment agencies jointly published guidance on regulating the disposal of low and intermediate level radioactive waste to specialised facilities on land.  In 2005 we decided to update this guidance because of developments in UK policy and revised international advice and recommendations, and also because specific guidance for near-surface facilities was required.  Moreover, the Nuclear Decommissioning Authority’s decommissioning programme will create large amounts of radioactive waste that will need to be disposed of in near-surface facilities, and the UK Government’s Managing Radioactive Waste Safely Programme is now underway to develop a geological disposal facility for higher activity wastes.

What do you hope to achieve with this guidance?

We want to provide a clear understanding of the principles and requirements that a developer or operator of a radioactive waste disposal facility needs to meet, before we can grant an authorisation for radioactive waste disposal.  We have set high environmental standards in the guidance to ensure protection of people and the environment, both now and in the future.  We believe that properly managed disposal of radioactive waste is consistent with our aim of creating a better place to provide a better quality of life for people and an enhanced environment for wildlife.

Who will use this guidance, and how will they use them?

The documents are aimed at developers of new radioactive waste disposal facilities and at operators of existing facilities.  The document will inform a developer’s or operator’s approach to the process of investigating and characterising a potential site, and also the design and construction of a facility at the site.  A developer or operator will need to take account of the principles and requirements that need to be met in developing an environmental safety case for a radioactive waste disposal facility. 

How have you engaged with stakeholders during the development of the guidance?

During late 2006, we held workshops with a range of stakeholders and consulted on the specifications for the two documents.  The views provided at the workshops helped guide the structure and content of the guidance documents. Subsequently during 2007 we developed the draft guidance in detail, and held further workshops with stakeholders on our emerging proposals.  Reports of the workshops are available from us on request.  We sought a broad range of views by inviting representatives from central and local Government, non-government organisations and industry to our workshops. Finally, we held a 3-month public consultation on our draft guidance in summer 2008.  Feedback from all these interactions has proved invaluable in helping us to improve our guidance.

How many responses did you get to your public consultation and how have you used the comments made to you?

There were about 20 responses.  We have taken account of all the points raised and changes have been made to the guidance in response to a number of the comments received.  We are preparing a consultation report, for publication within the next month, showing how consultees’ responses are reflected in the final guidance.

Have you chosen sufficiently high environmental standards to protect people and the environment in the future?

Yes.  The environmental standards in our guidance take account of international and national advice on standards for the long term protection of people and the environment.  Our environmental standards are also consistent with those adopted in other countries with radioactive waste disposal programmes. We have set a high standard for a developer or operator to meet, to ensure the environmental safety of radioactive waste disposal both during operation of a facility and in the long term after its closure.

How different is this guidance from the previous guidance?  What changes have you made?

We have updated the environmental standards that were set in the previous guidance as well as the principles and requirements within the guidance, to reflect developments nationally and internationally and give a clearer view of our expectations.  We have also provided more information on what we expect in an environmental safety case, and have set out the procedure that we would want a developer to follow so we can provide early advice and regulatory views.  In the revised guidance, we recognise the important role of dialogue with interested parties including local communities and the wider public.  We have provided more specific technical guidance, for example, on human intrusion.  We have discussed the policy and regulatory framework and described the process for authorisation of radioactive waste disposal. We have used plain English wherever possible, to make the guidance more accessible to non-technical readers.

How often will you revise this guidance, and how will national and international developments be taken into account?

We expect the guidance to have a lifetime of about 10 years – much the same as the previous document.  We may also provide supplementary guidance from time to time.  When reviewing it in future, we shall consider whether there are sufficient grounds for revising it to take account of national and international developments.  For the current guidance, we have considered not only policy and legislation in the UK, but also a range of publications from the United Nations International Atomic Energy Agency, Organisation for Economic Co-operation and Development Nuclear Energy Agency, and International Commission on Radiological Protection.  We have also considered European Directives such as the Basic Safety Standards Directive and international treaties such as the Oslo and Paris Convention (OSPAR) and the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.  

Why is HPA publishing separate advice? 

The Health Protection Agency (HPA) has produced revised advice on the radiological protection objectives for solid radioactive waste disposal.  HPA has a statutory function to provide radiological protection advice in the UK. It is not a regulator.  We regulate disposals of radioactive waste and our guidance informs developers and operators about what we expect in an environmental safety case for radioactive waste disposal facilities. Where our guidance relates to the radiological protection of humans, our approach is informed by HPA’s advice.  We explain the relationship between our regulatory guidance and HPA’s advice in annexes to our guidance.

Why is SEPA not the author of the geological disposal guidance? 

SEPA is not the author of the geological disposal guidance because Scottish ministers have opted for a policy of near site, near-surface storage of higher activity radioactive waste, rather than geological disposal.
