Engineer - Radiological Consequences Analyst

Join to apply for the Engineer - Radiological Consequences Analyst role at Rolls‑Royce SMR.

As a radiological consequences analyst, you will model radioactive releases during accident scenarios to define the radiological exposure to workers and members of the public.

Activities are expected to include:

• Engage with the safety analysis, system design, performance analysis and severe accident analysis areas to identify and scope candidate accident scenarios for RCA.
• Engage with the chemistry area to determine the fundamental source terms relevant to these accident scenarios.
• Develop Source Term and Radionuclide Transport (STaRT) methodologies to model the behaviour and transport of radionuclides during accident scenarios leading to atmospheric releases and/or onsite exposures.
• Implement appropriate models for iodine chemistry aspects with support from the accident chemistry area.
• Apply software tools to calculate dispersion of atmospheric releases to onsite and offsite receptor locations.
• Calculate radiological consequences, in terms of effective doses and conditional risks, to exposed individuals applying the ICRP radiological protection framework and with consideration of Urgent Protective Actions (UPAs) where appropriate.
• Apply the RR‑SMR gated review process to govern analysis work and solicit stakeholder feedback and endorsement of analysis scope and objectives.
• Produce quality technical reports following standard RR‑SMR policies and processes.
• Perform technical review of RCA tasks completed by other team members.

Key selection criteria for this role are:

• Strong understanding of radionuclide transport phenomena and analysis methods for design basis faults and severe accidents.
• Experience performing public and worker dose assessments to support safety cases or emergency planning.
• Familiarity with radiation protection principles and the ICRP framework; awareness of iodine treatment in RCA.
• Skilled in developing analysis methods and tools, including Python-based solutions, for safety‑critical applications.
• Experience applying structured, methodical approaches to analysis and adhering to software quality assurance processes.
• Knowledge of nuclear industry domain areas such as probabilistic safety assessment, design basis fault analysis, and emergency planning.
• Proven ability to deliver analysis tasks to time, cost, and quality, with strong communication and collaboration skills.
• Degree‑qualified in Engineering, Physics, Mathematics, or Computer Science; working toward chartered status preferred.

Salary and package:

• Salary between £40,000-£52,500 DOE
• Bonus – Performance related target opportunity 12.5%
• Benefits Allowance – £2,200 per annum, enabling you to create a bespoke package
• Pension – 12% employer and 6% employee contributions.
• Holidays – 28 days holiday (+ public holidays) and the ability to buy or sell up to 4 days.
• Private Medical Insurance – BUPA single cover health care
• Life Assurance – 6x pensionable pay
• £250 – One‑off payment for new starters for home office purchases
