Job Description

Overview / Responsibilities

Wood is seeking a mechanical engineer to provide Independent Nuclear Safety Assurance services at its Birchwood, Warrington, office. Wood provides a range of services in support of safe, available and affordable nuclear propulsion for the current Vanguard Class SSBN fleet and the Trafalgar Class and Astute Class SSN hunter/killer fleets, as well as supporting the design and development of the Dreadnought Class, the next generation of SSBN submarines.


Wood is looking for a full time Consultant at Engineer or Senior Engineer level to carry out Independent Nuclear Safety and Technical Assessment mainly of nuclear propulsion plant within its Mechanical Systems team based at its Birchwood office in Cheshire. Relevant background experience would include independent nuclear safety assurance, mechanical engineering and materials performance.


This role provides a diverse and exciting range of opportunities to support the UK submarine programme by undertaking safety and technical assessments of naval nuclear propulsion plant structures, systems and components, and covering the entire plant life cycle from concept design through to decommissioning. For example, tasks may be aimed to address issues associated with design, manufacture/build, maintenance and operation, including plant life extension, to ensure the submarine flotilla continues to deliver the necessary capability safely.


Key responsibilities will include:

  • Providing formal independent nuclear safety and technical assessment of documents relating to nuclear propulsion plant systems and components, and delivering the assessment output in formal letters, which may be presented to relevant safety and technical committees. Typical components assessed include reactor primary system valves and pumps
  • Performing assurance activities (inspection, advice and assessment) for all types of mechanical systems and components that provide nuclear safety functions in reactor primary and secondary systems, and also dockside facilities
  • Representing Wood at safety and technical meetings with clients, the plant authorisee, designers and safety case authors
  • Applying your personal skills and experience to other projects being carried out by Wood.

  • Ability to assimilate, analyse and provide judgements on complex technical and safety issues and arguments clearly and concisely, based on mature knowledge and understanding. Ability to communicate these clearly and succinctly in writing and orally
  • Knowledge and understanding of the ageing/failure mechanisms of high integrity pumps, valves and other reactor system components
  • Experience of providing assurance activities (formal independent assessment, advice and inspection) for mechanical plant systems and components in safety or mission critical applications is desirable
  • Good interpersonal skills, to work as part of a team
  • A willingness to travel within the UK if required for an individual project
