Technical Lead - Reactivity Control Analysis

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 Reactivity Safety Analysis Technical Lead will be responsible for the technical and programme delivery of the thermal and hydraulic performance analysis to verify reactor protection during transient and faulted operations.

The role will involve working alongside systems design team 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 provide technical leadership and coordination of a small team of engineers to ensure the delivery of analysis which supports design development of the reactor protection systems (including scram and boron injection), informs code validation activities and ultimately underpins the reactor plant safety case during Generic Design Assessment (GDA) by the Office of Nuclear Regulation (ONR).  This will include leading the development of robust and validated analysis methods using industry standard approaches, the creation and management of representative models, and assessment of transient performance during faulted and safety systems operations.

The reactivity analysis technical lead will have expertise in thermal hydraulic and physics analyses of reactor plant designs, an excellent knowledge of reactor protection system designs, familiarity with nuclear plant analysis codes (including RELAP and CTF), as well as a strong foundation in safety principles and associated analysis approaches (e.g BEPU). 

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 direct the analysis programme, including definition of the analysis basis, selection and justification of appropriate method, and technical supervision to supporting analysts.
  • Define and manage requirement traceability from design through to analysis, models and method validation.
  • Ensure appropriate quality is achieved in designated aspects of the 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 reactor protection 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.
