1.4.5.1.2.1 Regulatory regime applicable to nuclear facilities in the UK

The following regime is applicable to both EDF Energy’s generation and new build assets in the UK.

Regulatory notice

Basic nuclear facilities in the United Kingdom

In the United Kingdom, EDF Energy is required, under the Nuclear Installations Act 1965 (“NIA 1965”), to hold a nuclear site licence for each of its existing nuclear power plants and nuclear power plants under development and comply with a certain number of licence conditions. The Planning Act 2008 (“PA 2008”) introduced the concept of Development Consent Orders (“DCOs”), which are the authorisations required to build a new nuclear power plant in the UK. The DCO application process involves conducting an environmental impact assessment, implementing environmental mitigation measures and holding a certain number of public consultations.

Office for Nuclear regulation (ONR)

In the United Kingdom, the Office for Nuclear regulation (ONR) and the Environment Agency (EA)/Scottish Environment Protection Agency (SEPA) are responsible for the safety, security, emergency planning and environmental regulation that applies to the UK’s nuclear sites.

The ONR is responsible for the regulation and inspection of nuclear facilities and the following laws are overseen by the ONR:

the Health and Safety at Work Act 1974 (HSWA 1974), which defines EDF’s obligations for the safety of workers and others on its sites;
the Nuclear Installations Act 1965 (NIA 1965), under which operators of nuclear power plants need to obtain a nuclear site licence, comply with that licence and maintain nuclear liability insurance;
the Energy Act 2013 (Part 3) (EA 2013) conferred statutory body status on the ONR. It also confirmed ONR’s purposes in respect of nuclear safety, nuclear site health and safety, nuclear security, nuclear safeguards and transport. Schedule 8 of the Act details the powers of ONR Inspectors;
the Ionising Radiation regulations 2017 (IRR 2017), which are based on the Basic Safety Standards Directive and provide for the protection of workers and the public against ionising radiation;
the Environmental Permitting (England and Wales) regulations 2016 and the Environmental Authorisations (Scotland) regulations 2018. The 2016 regulations provide the current permitting framework for radioactive substances. The 2018 regulations provide a framework for the authorisation of environmental activities and currently include only Radioactive Substances activities. The EA and SEPA are the responsible regulators for these 2016 and 2018 regulations respectively.

When assessing the measures that may be required to reduce the risks from activities within the scope of HSWA 1974, the ONR requires risks to be reduced as low as reasonably practicable.

The ONR uses the powers granted to it under the NIA 1965, the EA 2013 and the 36 standard Nuclear Site Licence Conditions as the basis for its monitoring and enforcement regime. The ONR has extensive inspection powers allowing it to inspect nuclear facilities, request documents and conduct investigations. It begins with a detailed review and assessment of the safety of the design and continues throughout the operation and decommissioning of the facilities.

Under the NIA 1965, the ONR is authorised to grant licences to applicants and to impose licence conditions which may be varied or revoked. In particular, the ONR can prohibit certain nuclear operations or revoke the licence of a nuclear site. More ordinaryly, the ONR may agree to specific actions, approve arrangements or require changes/variations to operations. The maximum penalty for non-compliance with safety legislation is an unlimited fine or imprisonment for a term not exceeding two years for directors or both.
