Job description

The Nuclear Safety Inspector role

Nuclear Inspectors are expected to be capable of undertaking a variety of roles:

  • Inspecting sites
  • Assessing technical safety cases
  • Enforcing the law and influencing improvement in safety cases
  • Investigating incidents
  • Developing strategic approaches to secure high standards in the industry
  • Managing nuclear research contracts etc.

The role of a Nuclear Inspector is varied and you are likely to undertake a range of duties during your career. Some Inspectors concentrate on undertaking planned and reactive inspections on site, while others will mainly assess safety submissions or manage discrete intervention projects.

However, the focus is on working as teams to ensure compliance, reassure the public and improve safety standards. When Inspectors find shortcomings in compliance they initially provide advice but may issue verbal and written warnings. The powers available to inspectors enable them to serve Enforcement Notices and ultimately initiate prosecutions. There is also a wide range of powers available under nuclear license conditions.

Criticality Safety

What does criticality safety mean in ONR?

Criticality safety in ONR is about ensuring that workers and members of the public are adequately protected from the hazards of inadvertent nuclear chain reactions (“criticalities”) arising on nuclear licensed sites or from the transport of nuclear materials. For nuclear licensed sites, our criticality specialists assess licensees' safety cases in the light of our safety assessment principles to ensure that plant is designed, constructed, operated, maintained and decommissioned in such a way that exposure to criticality hazards is kept as low as reasonably practicable. Our criticality specialists also assess applications for the transport of fissile material in the public domain.  As such, our criticality specialist inspectors are expected to have a good understanding of criticality physics and practical experience in the application of criticality safety techniques and methodologies, in particular using the hierarchy of control measures. They also expected to have a good understanding of the legal requirements governing the public transport of fissile materials.

In terms of protecting the public, our criticality specialists might well find a role in assessing the adequacy of on-site and off-site emergency arrangements and in supporting ONR's own arrangements for emergency preparedness and response.
