Job Description

The Opportunity

As part of its 2025 strategy ONR is committed to being a modern and transparent regulator, delivering trusted outcomes and value. We are making substantial investments in new digital technologies and skills to enhance our regulatory processes and management of information.

As the UK’s independent nuclear regulator, our mission is vital to the nation’s safety and security. We protect society by securing safe operations at nuclear facilities across our nation.

This is an exciting role critical to the decarbonisation of the UK’s economy; our national defence; and the decommissioning of our nuclear legacy. A career with ONR will provide you with opportunity to lead and shape our society’s future use of nuclear technology.

The Role

As an inspector your job will be varied, and you are likely to undertake a range of roles across the sector; from regulating the construction of new nuclear build to the decommissioning of legacy facilities. Some inspectors concentrate on undertaking planned and reactive inspections on site, while others will assess safety submissions or manage discrete intervention projects. Additionally, there may be opportunities to conduct investigations, manage research projects and mentor and develop the next generation of inspectors.

As an internal hazard’s specialist inspector, you will consider hazards (to plant or safety related structures) that originate within the site boundary and are due to initiating events over which the site operator has some form of control. Internal hazards include internal fire, flooding, explosions, dropped loads, pipe whip, jet impact, internal missiles, to name just a few. One key internal hazard for all nuclear sites is fire. Indeed, assessments of how fires might threaten nuclear plant and safety equipment, and the adequacy of the measures put in place to prevent the spread of fires and their consequences are of paramount importance. The consideration of fire as an internal hazard differs from life fire safety in that the regulatory focus from internal hazards is judging the adequacy of the operator's safety case (and its implementation) in dealing with fires with radiological consequences. As an internal hazard’s inspector, your expertise will ensure that safety cases adequately consider the whole range of potential internal hazards, and duty holders provide suitable measures to prevent them, and to protect plant against their effects.

Line Management Responsibilities

  • None currently, however, at this level there could be an expectation to manage staff in the future.
