Job Description
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Safety Methods Engineer based in the United Kingdom.
This role provides an opportunity to contribute to the development and qualification of advanced safety analysis methods for next-generation nuclear energy systems.
The successful candidate will support critical engineering activities focused on licensing, thermal-hydraulic modeling, and reactor safety evaluations.
Working within a multidisciplinary environment, this position combines technical innovation, computational analysis, and regulatory excellence.
The role involves developing analytical methods, improving simulation capabilities, and ensuring the reliability of safety-focused engineering solutions.
The ideal candidate will bring expertise in thermal-hydraulic analysis, numerical modeling, and verification and validation processes.
This is a high-impact opportunity for an engineer who wants to help shape the future of advanced reactor technologies while working on complex scientific challenges.
Accountabilities
The Senior Safety Methods Engineer will develop, improve, and qualify engineering methods used for reactor safety analysis and licensing activities. The role requires close collaboration with technical teams to enhance modeling capabilities, ensure analytical accuracy, and support reliable decision-making throughout advanced reactor development programs.
- Develop system-level thermal-hydraulic analysis methods, including modeling strategies, numerical approaches, and closure models.
- Perform steady-state and transient system-level analyses to evaluate model behavior, accuracy, and performance limitations.
- Support method qualification activities, including numerical verification, applicability assessments, and performance characterization.
- Develop and integrate closure models and empirical correlations related to heat transfer, pressure drop, mixing, and component-level physics.
- Identify modeling limitations and support method improvements through sensitivity studies and technical evaluations.
- Create automated workflows and engineering tools for model preparation, execution, post-processing, and repeatable analysis processes.
- Document modeling methodologies, assumptions, applicability ranges, and numerical performance for engineering design and licensing activities.
- Collaborate with multidisciplinary teams to ensure thermal-hydraulic methods effectively support plant design, safety analysis, and coupled simulation workflows.
- Contribute to the development and maintenance of system transient analysis codes and reactor simulation capabilities.
- Perform reactor transient analyses, benchmarking activities, and comparisons against integral and separate effect test data.
- Support code assessment, adequacy evaluations, verification, and validation activities.
- Apply and improve quality assurance practices for modeling activities, ensuring traceability, configuration control, and reproducibility of engineering methods.
