ONR Strategy 2020-25

The strategy places attention on what our stakeholders expect from us and we intend to meet those needs. Throughout the strategy, we have emphasised the importance of ONR taking an enabling approach to regulation: working together with stakeholders to influence improvements in nuclear safety and security.

The strategy sets out the factors that will influence our work and the assumptions we have made about regulating the nuclear sector in the next few years, as well as how we deliver the commitments we have made to the public, ministers and government, licensees, dutyholders and our staff. Information on corporate risk, resources and finance planning is also contained in the strategy.

Strategies and plans

Annual Report and Accounts

ONR is required by legislation to produce an Annual Report and Accounts which summarises our performance alongside other key developments across the organisation. The arrangements for and management of nuclear safety and security across UK nuclear sites, transport of radioactive materials and safeguarding nuclear material, are rightly measured against the highest standards.

Chief Nuclear Inspector's Annual Report on Great Britain’s Nuclear Industry

This report provides an independent, authoritative view of safety, security and safeguards performance across the industry over the last year.

2001 to 2015

Guide to nuclear regulation in the UK

This guide provides an explanation of the nuclear regulatory regime by describing ONR's activities and how ONR carries out its work.

A guide to enabling regulation in practice

Enabling regulation is a constructive approach with dutyholders and other relevant stakeholders to enable effective delivery against clear and prioritised safety and security outcomes. This guide is designed to illustrate working examples of enabling regulation in practice.

Scheme of delegation

The scheme of delegation sets out who has the authority to make decisions within ONR.

Business Impact Target (BIT)

As a statutory regulator ONR is subject to the Government’s Business Impact Target (BIT) following the provisions of the Small Business, Enterprise and Employment Act 2015 which aims to:

  • reduce regulatory burdens on business and voluntary or community bodies;
  • ensure greater transparency around the impact of regulation on business; and,
  • provide greater incentives for regulators to design and deliver policies that better meet the needs of business.

ONR is required to publish an assessment of the economic impact on business of changes to regulatory policies and practices which are in scope of the BIT and is required to publish:

  • BIT assessments for qualifying regulatory provisions (QRPs) along with the BIT score
  • a summary of non-qualifying regulatory provisions (NQRPs)

How we charge for nuclear regulation

Established by the Energy Act 2013, the Office for Nuclear Regulation (ONR) is empowered by diverse legislation to recover the cost of its services from dutyholders.

As we strive to inspire a climate of respect, trust and confidence among our stakeholders, this booklet clearly explains how this charging system works.
