Working within the specialist Performance & Analysis function, you will lead the development and application of thermal-hydraulic models used to assess reactor plant performance under normal operation, transient conditions, and fault scenarios. You will take technical ownership of complex analysis activities, leading small teams to deliver high-quality modelling and simulation outputs that support reactor design, safety system performance, and safety case development. The role requires close collaboration with multidisciplinary teams across design, safety, and testing to ensure robust and validated engineering solutions.
