Nuclear Safety Inspectors – Electrical Engineering

Within ONR, we assess and inspect the ability of electrical engineering systems to satisfactorily perform their role in providing energy to support nuclear safety systems or security systems under a range of operating conditions. ONR is also responsible for regulating conventional industrial safety on GB nuclear sites including compliance with the Electricity at Work Regulations 1989 and other relevant statutory provisions.

We use international standards and guidance and established relevant good practice to determine that risks arising from electrical systems, or their maloperation, has been reduced, so far as is reasonably practicable.

ONR is looking for experts with good experience of electrical power equipment, high integrity electrical power system design and failure causes. Knowledge of the practical challenges of all parts of the system lifecycle would be very beneficial.

The ability to articulate the purpose of techniques to avoid and contain failures through architectural measures such as use of redundancy, diversity, separation, and segregation, etc. would be advantageous. It is a key requirement to be able to communicate the challenges associated with complex electrical safety systems to a wider group of nuclear inspectors from other disciplines. It would be an advantage for applicants to have knowledge and experience of structured systematic failure analysis techniques such as fault trees, event trees and FMEA. 

We are looking for people with in-depth knowledge of the design, qualification, installation, commissioning, maintenance and operation of electrical systems particularly those used in an emergency role in the event of the failure of the grid based power supply systems. Ideally, we would expect you to have been involved in the design and commissioning of high integrity standby electrical power supply systems of the type found in nuclear installations, high hazard facilities or in applications such as electrical support for mission critical services.

As well as providing guidance and advice within your specialism, you would be expected to be able to perform technical assessment of the electrical engineering aspects of safety cases and make judgements, with support from other specialist inspectors as appropriate. 

Experience

We are looking for people with specialist electrical power system knowledge and experience in at least two of the following areas:

  • The design and management of either generator or battery-based high availability power supply systems;
  • Design, procurement, qualification, installation, commissioning, maintenance, and operation of high availability power supply systems;
  • Protection coordination and stability studies under faulted conditions of high availability power supply systems;
  • The probabilistic and deterministic failure analysis of high availability power supply systems used at mission-critical, nuclear or high hazard facilities, including the failure modes of equipment;
  • Facility and site-level lightning and earthing system design, study, maintenance, and periodic review at nuclear or high hazard facilities; and
  • Industrial electrical safety practices compliant with the Electricity at Work Regulations 1989 to achieve the safety of people and equipment during its lifecycle.
