Engineer - Radiological Consequences Analysis

Role Title: Radiological Consequences Analyst

We are Rolls-Royce SMR and we’re doing something that’s never been done before. We’re revolutionising an industry. That’s a once-in-a-career opportunity for those excited by such a challenge. This is more than just a job; this is a legacy.

We are now recruiting for a Radiological Consequences Analyst to join our Radiological Consequences team, which performs radiological consequences analysis (RCA) of the RR-SMR design during faulted and accident conditions to substantiate the safety of the power station.

About the Role:

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

Activities include:

• Engage with safety analysis, system design, performance analysis, and severe accident analysis areas to identify and scope candidate accident scenarios for RCA
• Work with chemistry teams to determine fundamental source terms relevant to accident scenarios
• Develop Source Term and Radionuclide Transport (STaRT) methodologies to model radionuclide behaviour and transport during accident scenarios
• Implement iodine chemistry models with support from accident chemistry specialists
• Apply software tools to calculate dispersion of atmospheric releases to onsite and offsite receptor locations
• Calculate radiological consequences, applying the ICRP radiological protection framework and considering Urgent Protective Actions (UPAs)
• Apply RR-SMR gated review processes to govern analysis work and solicit stakeholder feedback
• Produce quality technical reports following RR-SMR policies and processes
• Perform technical review of RCA tasks completed by other team members.

The RCA team uses methodologies ranging from Excel-based calculations to Python-based solvers. Atmospheric dispersion is modelled using ADMS and PACE software.

Due to the safety-critical nature of the modelling we undertake, excellent quality-management processes including code verification and validation are essential. All analysts have a role in ensuring quality outputs through rigorous process adherence and supporting continuous improvement of methods and tools.

We’ll Need You To:

• Perform RCA activities and collaborate across engineering disciplines
• Develop and implement RCA methodologies and tools
• Deliver high-quality technical reports and reviews
• Ensure compliance with safety case and regulatory requirements

Key Skills Required:

• 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

Location:

Hybrid working with one of the following locations as your primary site: Derby, Manchester or Warrington

Salary and Package:

The salary band for this will be between £40,000–£52,500 dependent on the skills, values, and knowledge you bring. There may be some flexibility with the starting salary in exceptional cases, and, in due course, there is the potential for you to develop the role further.

Benefits include:

• Bonus - Performance-related target opportunity 12.5%
• Benefits Allowance - £2,200 per annum for a bespoke package
• Pension - 12% employer and 6% employee contributions
• Holidays - 28 days (+ public holidays) with ability to buy or sell up to 4 days
• Private Medical Insurance - BUPA single cover
• Life Assurance - 6x pensionable pay
• Home Office Support - £250 one-off payment for new starters

You’ll be joining a forward-thinking organisation that values transparency, fairness, and innovation. We offer a flexible, inclusive, and supportive working environment, opportunities for career growth in a rapidly scaling business, and a culture that values diversity, innovation, and continuous learning.

Selection Process:
