Radiation Shielding Engineer

Location: Milton Park, Abingdon
Salary: Competitive
Job type: Permanent

The role

The commercialisation of fusion requires that a number of fascinating design challenges are met. One of these is radiation shielding. The size and performance of a spherical tokamak is strongly dependent on reducing the thickness of the shield that protect the superconducting coils from the 14.1MeV fusion neutrons and gamma rays. Provision of a bio-shield is also essential. We are looking for a radiation shielding engineer to play a key part in solving some of these challenges by applying sound physics and engineering judgement to develop shielding designs which meet the design requirements.

Responsibilities

  • Assist in the development of 3D radiation transport models of prototype Spherical Tokamaks
  • Produce neutron and gamma radiation calculation results (including heat and dose deposition and fluence spectra) both internal and external to the Tokamak geometry
  • Propose and perform validation and verification activities on radiation transport models
  • Advance the maturity of shielding design solutions from initial conceptualisation through to detailed design
  • Present technical information relating to shield design performance to both expert and non-expert audiences
  • Interface and collaborate with a variety of in-house and external resources

Selection criteria

  • Experienced user of MCNP as a radiation transport code
  • Experienced user of activation/transmutation codes, primarily FISPACT but alternatively ORIGEN or similar.
  • Experience in nuclear fusion technology and the principles of Tokamak design
  • In-depth knowledge of radiation shielding and neutronics
  • Knowledge of techniques on how to provide assurance of radiation modelling results through computational and experimental validation and verification
  • An ability to communicate effectively to peers and management
  • A proven track record of solving complex problems in a rigorous, organised fashion through effective planning and review
  • Computationally competent in the ability to use radiation transport software efficiently as well as preparing effective analytical results through word processing and other software tools
  • Highly motivated to deliver against challenging objectives in a compressed timescale
  • A proactive and self-reliant approach to work with minimal supervision
  • Experience of working well in a team of scientists and/or engineers.

Desirable selection criteria

  • Experience and knowledge of other radiation transport methodologies, including deterministic, Monte Carlo and point kernel techniques
  • Knowledge of the effects of radiation on materials and Electronic, Electrical and Electro-mechanical (EEE) devices
  • Experience in regulatory interaction, including ALARP justifications
  • A PhD or MSc (or equivalent) in Nuclear Fusion, or a related subject
  • Professionally recognised qualifications such as Chartered Engineer or Chartered Physicist, or international equivalents
  • Understanding and awareness of intellectual property.

Benefits 

  • 25 days holiday, pro rata (plus bank holidays)
  • Company pension scheme
  • Eligible for company share option scheme after 1 years’ service
  • Company bonus scheme, discretionary, dependant on performance
  • Private medical insurance after 3 months service
