Technical Lead - Reactor Plant CFD

Location: Derby or Warrington

Organisation: Engineering

Department: Plant Engineering

Required Security Clearance: BPSS

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 Reactor Plant Performance Lead, the technical lead for Computation Fluid Dynamics (CFD) analysis will be responsible for ensuring the coordination, delivery and quality of CFD analyses required to verify the reactor plant design. 

The role will involve working alongside the plant designers and reactor plant analysis teams to understand the technical nature of the reactor plant design and produce thermal hydraulic analyses which characterises system performance, informs intelligent design decisions and ultimately verifies the performance and safety of the final design. 

The successful candidate will set the strategic direction for the development of an in-house CFD capability for the SMR project as well as providing technical leadership and coordination for CFD analyses undertaken in the supply chain.  They will ensure the delivery of the requisite evidence to support design development, inform thermal hydraulic validation and ultimately underpin the reactor plant safety case during Generic Design Assessment (GDA) by the Office of Nuclear Regulation (ONR). 

The technical lead will have expertise in producing CFD analysis for Safety Class 1 reactor plant systems, as well as a strong foundation in nuclear safety principles and validating thermal hydraulic analysis methods. 

Key Responsibilities

  • Work with the plant design engineers to understand the technical nature of the reactor plant as well as the evidence required to inform technical decision making verify plant performance.
  • Apply technical expertise to lead and coordinate CFD analysis and validation activities.  This includes the provision of technical supervision for in-house analyses as well the specification and management of analysis conducted in the supply chain.
  • Define and manage requirement traceability from design through to analysis, models and method validation.
  • Ensure appropriate quality is achieved in by the CFD analysis programme.  Undertake local technical reviews and input to the main project technical review gates. 
  • Work alongside the method validation lead to ensure appropriate method validation is in place at each analysis stage, and provide technical expertise into the code validation programme and rig design programmes.
  • Develop and deliver detailed plans for the assigned technical discipline.
  • Act as technical authority for CFD analysis internal and external to the company. 
  • Understand and articulate technical and programme risks, managing them as appropriate with the Reactor Plant Performance Lead.
  • Work with due regard to Health, Safety and Environment. Comply with corporate, business and legislative requirements.  Champion company values, including Diversity, Equity and Inclusion.
