Office for Nuclear Regulation
We are the UK’s independent nuclear regulator for safety, security, and safeguards. Our mission is to protect society by securing safe nuclear operations.
ONR's work calls for a high level of expertise and a wide range of disciplines. All the technical skills found in any engineering-based industry can be found in ONR, as well as reactor physics, radiological protection, and a number of specialised areas.
Vital to the effective operations of ONR is our corporate centre which incorporates a broad range of specialisms including finance, information technology, human resources, policy and communications, procurement, project management and administration.
We deliver five statutory purposes to ensure safe nuclear operations now and in the long term. These are:
nuclear safety;
nuclear site health and safety;
nuclear security;
nuclear safeguards; and
safety of transport of nuclear and radioactive materials
We have the legal authority to regulate nuclear safety, nuclear security and conventional health and safety at the 35 licensed nuclear sites in Great Britain (GB). This includes the existing fleet of operating reactors, fuel cycle facilities, waste management and decommissioning sites, as well as licensed and, in part*, authorised defence sites, together with the regulation of the design and construction of new nuclear facilities, including the supply chain.
*on authorised defence sites we regulate the Health and Safety at Work Act 1974, including Radiation (Emergency Preparedness and Public Information) Regulations 2019 and Ionising Radiation Regulations 2017
Our nuclear security regulation ensures the adequacy of security arrangements for dealing with special nuclear material and special nuclear information within the civil nuclear industry and we also regulate the safety and security of the transport of civil nuclear and radioactive materials by road, rail and inland waterway, extending our regulation across a large number of duty holders.
On 1 January 2021, we became the UK nuclear safeguards regulator for the domestic standards regime and began to operate the UK State System of Accountancy for and Control of Nuclear Materials (SSAC).
Our colleagues are from all walks of life with varied personal experiences and career journeys into ONR including:
We offer a diverse range of careers with offices across Bootle, Cheltenham, and central London. We want the best people for our roles. As an inclusive employer we value individuals’ contributions, regardless of their age, gender, race, ethnicity, disability, sexual orientation, social background, religion, or belief. Our values ‘supportive, open-minded, fair and accountable’ are central to this.

Our values set the tone, and underpin how we will deliver our vision and mission, how we will establish the behaviours we need in order to be our best, and how we will create a culture of inclusion and excellence.
Fair
We are inclusive and respect people for who they are. We welcome and value diverse perspectives, in and outside of ONR, and share our views openly and constructively. We make decisions fairly, based on the best, broadest available information. We recognise good performance and behaviour and address exceptions.
Open-minded
We proactively seek new and innovative ways of working to help each other and ONR excel. We are open to ideas and feedback from our colleagues and stakeholders and take all opportunities to improve ourselves, our teams and our organisation.
Accountable
We act with integrity and honour our commitments. We are accountable for our actions, behaviours and impact on others. We own our mistakes and learn from them. We ask for and offer help when needed.
Supportive
We show that we care for each other and our stakeholders, making a positive difference to others’ wellbeing and performance. We listen, trust each other and work together to harness our collective skills, knowledge and experience to make better decisions.
We are proud of how our people have responded to change since our inception in 2014. As we adapt to new challenges, we will continue to invest in our staff, building capability, resilience and wellbeing in our great teams, underpinned by a focus on inclusion and excellence as standard.
Everyone will show accountability for creating a healthy, inclusive organisational culture that embraces diversity and every individual, and enables everyone to excel – we recognise that is a job for everyone, not just a few.
We will operate in a culture of excellence, where we get it right first time and address issues at root cause – driving value in a systematic way, at individual, team and organisational level.
Our leaders and managers will develop to become equally competent in people and technical matters. They will lead change and improvement alongside operational delivery as a matter of course.
Having invested in our capacity and an ONR Academy over recent years, we should see the benefits of a skilled and increasingly experienced workforce which is well aligned and works across functions.
We will:
a. continue to develop a positive, inclusive culture that consistently reflects our values and focuses equally on delivery and behaviour;
b. lead change effectively, so we all take personal accountability and credit for organisational success;
c. bring greater focus to improving performance and productivity through training, and enhanced leadership and management capabilities;
d. support suitably qualified, experienced and professional inspectors to be more joined-up by working across our functions and regulatory purposes;
e. proactively seek and respond to feedback (internally and externally) to improve our performance
