Radioactive waste advisers
What are RWAs?
Radioactive Waste Advisers (RWAs) are specialists in radioactive waste disposal and environmental radiation protection. UK legislation requires anyone managing radioactive substances to appoint qualified advisers, known as radiation protection experts, to provide advice on radiological protection.
An RWA must demonstrate competence in the RWA syllabus. This can be met by:
Individual RWAs, who are competent in all parts of the syllabus; or
Corporate RWAs, where a group of individuals collectively meets the full competence requirements to advise a nuclear permit holder.
The RWA scheme was developed jointly by SEPA, the Environment Agency and the Northern Ireland Environment Agency, with extensive stakeholder engagement. Details on how the environment agencies meet their legal obligations and implement the scheme are set out in the Statement on Radioactive Waste Advisers, published in May 2011 and updated in July 2020 and February 2024.
Who needs an RWA?
Anyone who has a relevant permit or registration under the Environmental Authorisations (Scotland) Regulations 2018, a permit under the Environmental Permitting Regulations 2016 or an authorisation under the Radioactive Substances Act 1993 (Northern Ireland) to manage radioactive waste needs to appoint a Radioactive Waste Adviser.
Who assesses the competence and suitability of RWAs?
Individual RWAs are assessed by assessing bodies approved by the environment agencies. A Corporate RWA is assessed in accordance with corporate arrangements put in place by a nuclear permit holder and approved by the environment agencies.
The permit holder is responsible for assessing the suitability of RWAs. The environment agencies may check the permit holder’s procedures for determining and assessing suitability during routine inspections, as for any other permit condition.
What is the RWA Approval Board?
The environment agencies have set up an RWA approval board, which operates in accordance with a constitution agreed by the agencies.
The board’s purpose is:
- to oversee the operation of the scheme for the recognition of Radioactive Waste Advisers
- to review and maintain the environment agencies’ statement on Radioactive Waste Advisers
- to approve assessing bodies and corporate arrangements
In addition to SEPA representation, the board also has members from the Environment Agency (EA), the Northern Ireland Environment Agency (NIEA) and Natural Resources Wales (NRW).
Members from the nuclear and non-nuclear industries participate in an advisory capacity, invited through the Nuclear Industry Environment Liaison Group (NIELG) (Great Britain), the Scottish Non-Nuclear Industry Liaison Group (SNNILG) (Scotland), and the Small Users Liaison Group (SULG) (England and Wales). Visit our stakeholder page for more information on these advisory groups.

How can I become recognised as a RWA?
To become recognised as an individual RWA you need to be able to demonstrate competence in all parts of the RWA Syllabus to an Approved Assessing Body.
Competence for RWAs is defined as ‘the combination of knowledge and experience that equips an individual or group of individuals to provide expert advice on radioactive waste management and environmental radiation protection’. It is likely to be obtained by a combination of education, training and practical experience.
RPA 2000 has been approved as an Assessing Body for RWAs and information on its application and assessment process can be found on the RPA 2000 website.
The following guidance provides help for those who want to become certified RWAs or those who need to appoint RWAs:
