Severe Accident Analysis Lead

Location: Derby or Warrington

Organisation: Regulatory Affairs

Department: GDA

Required Security Clearance: BPSS

Morson Talent are working in partnership with Rolls Royce SMR to appoint a Severe Accident Analysis Lead to join their growing Safety team. You can be based at either Warrington or Derby with the option of hybrid working.

The Company
Rolls-Royce SMR is a start-up joint special purpose vehicle (SPV) business, specifically created to design, construct and deliver a new fleet of Small Modular Reactors power plants that will be a critical and strategic player in the race to Net Zero carbon emissions globally. Spun out of Rolls-Royce with its pedigree in engineering excellence but also attracting world class inward investment this is an exciting new business with an optimistic opportunity to be a global player in the coming years.

The Post
Reporting to the Nuclear Safety Case and Licensing Lead, successful candidates will be responsible for developing a severe accident analysis method and delivering the requisite safety analysis which both verifies the reactor plant design and informs the Level 2 and 3 Probabilistic Safety Assessments.

The role will involve working alongside the design, performance and safety teams to understand the technical nature of the reactor plant design and producing containment and consequence analyses which characterises system performance, informs intelligent design decisions and ultimately verifies the performance and safety of the final design.

The Severe Accident Analysis Lead will develop and deliver a strategy that supports design development as well as entry into and completion of the Generic Design Assessment regulatory process. They will form a small team of engineers that develop robust and validated analysis methods using industry standard codes (including MAAP, GOTHIC and PACE), create representative models of the reactor plant design, and assess plant transient response during complex accident scenarios.

Key Responsibilities
• Work with the design and safety teams to understand the technical nature of the reactor plant as well as the evidence required to inform technical decision making verify plant performance.
• Develop and deliver the severe accident analysis programme, including definition of the analysis basis, selection and justification of appropriate method, and technical supervision to supporting analysts.
• Develop robust plans for the severe accident analysis work stream. Prioritise team activities to ensure on time delivery, cost and quality for all project deliverables.
• Define and manage requirement traceability from design through to analysis, models and method validation.
• Ensure appropriate quality is achieved in all aspects of the analysis programme. Support local technical reviews and input to the main project technical review gates. Work alongside the method validation leads to ensure appropriate method validation is in place at each analysis stage.
• Act as technical authority for severe accident analysis both internal and external to the company. support technical and project reviews when required.
• Understand and articulate technical and programme risks and manage them as appropriate with the E3S Manager.
• Work with due regard to Health, Safety and Environment. Comply with corporate, business and legislative requirements. Champion company values, including Diversity, Equity and Inclusion.

Required Competencies
• Business Case - Apply technical judgement to ensure the programme meets business needs. Manage the business case including determination of business benefit (tangible and intangible) and the measurement of actual benefits.
• Create strategy (capability) - Contribute to the development of integrated strategy for the business.
• Manage programme resources - define needs, recruit, develop and manage personnel to meet agreed plans and budgets.
• Technical authority for the relevant areas.
• Deliver Programme - Define a project/programme of work, deliver programme milestones in line with agreed plans and budgets, manage risks, etc.
• Awareness and understanding of SMR Quality Assurance (QA) processes and standards
• Knowledge of Pressurised Water Reactor (PWR) design, plant and behaviour during normal and abnormal operation
• Environmental, Safety, Security and Safeguarding (E3S) regulations and principals (including application of As Low As Reasonably Practicable (ALARP) and Best Available Technique (BAT) principals)
• E3S case methods (including nuclear safety classification), case structure and document generation
• Generation and management of Verification and Validation (V&V) plans and evidence
• Thermal hydraulic principles and calculation
• Reactor Island design and operating philosophy knowledge

Qualifications & Experience
• Qualified to degree level or equivalent in Mechanical Engineering or a related discipline.
• Chartered Mechanical Engineer or equivalent professional accreditation.
• Knowledge of Pressurised Water Reactor technology
• A solid understanding of the principles of nuclear safety
• Experience in the development of Severe Accident Management Guidelines
• Experience on accident progression phenomena modelling using tools such as MAAP or MELCOR
• Experience of Level 3 PSA techniques and software, such as PC COSYMA, PACE, ADMS or similar
• Experience in delivering analysis programmes in support of design development from initial concept through to detailed design definition.
• Planning and organising skills to manage programme activities and deliverables.
• Ability to communicate effectively with any audience, quickly establishing credibility and buy-in.
