Core Responsibilities
- Lead a small team to model fluid and thermal systems that extract power from the nuclear core and ensure safe reactor operation.
- Produce models and analyses demonstrating reactor operation, and work closely with system designers to optimise plant design and safety systems for maximum safety, performance and value for money.
- Support development and authoring of safety‑case documentation and contribute to key safety‑case sections.
- Collaborate across engineering and non‑engineering disciplines to define analysis requirements and communicate results.
- Apply technical expertise to develop capability, mentor staff and lead interfaces with other business areas.
- Develop robust, automated analysis routes around the analysis codes, primarily using Python on Linux‑based HPC resources.
- Benchmark codes against test data and support the design of large‑scale test rigs where required.
Required Qualifications & Skills
- Strong understanding of fluid dynamics and thermal processes, with experience applying structured, methodical analysis approaches.
- Hands‑on experience using industry‑standard fluids and thermal analysis software; familiarity with nuclear thermal‑hydraulics tools (RELAP, FLOMASTER, VIPRE, CTF, GOTHIC desirable).
- Proven ability to develop analysis methods, models and tools, including Python‑based solutions, to support design and safety‑case development.
- Skilled in writing clear, structured analysis reports and contributing to safety‑case documentation.
- Experience in verification, validation and uncertainty quantification of analysis models, including benchmarking, and adherence to software QA processes.
