Position Title: Senior Safety Methods Engineer
Position Description: Protingent Staffing has an exciting contract Senior Safety Methods Engineer opportunity.
Job Responsibilities:- Develop system-level thermal hydraulic analysis methods, including modeling strategies, numerical approaches, and closure models.
- Perform steady-state and transient system-level analyses to characterize model behavior, assess method performance, and define method fidelity requirements.
- Support method qualification, including numerical verification, applicability envelopes, and performance characterization.
- Formulate and integrate closure models and empirical correlations (e.g., heat transfer, pressure drop, mixing, component-level physics) into existing analysis frameworks.
- Identify modeling gaps and support method enhancement using and sensitivity studies.
- Develop automated workflows and tools for model setup, execution, post processing, and repeatable method application.
- Document modeling methodologies, assumptions, method applicability, and numerical performance for design processes and licensing support activities.
- Work across disciplines to ensure thermal hydraulic methods integrate effectively with plant design, safety analysis, and coupled simulation workflows.
- Apply and improve Company's SQA and NQA 1 modeling practices, ensuring traceability, configuration control, and reproducibility of methods.
Job Qualifications:- Degree in Mechanical, Nuclear, Chemical Engineering, or similar fields, with 3+ years of experience in system-level thermal hydraulic modeling and method development for nuclear or complex energy systems.
- Demonstrated experience in developing or improving analysis methods, including numerical scheme development, closure model formulation, and stability/accuracy optimization strategies.
- Experience performing system-level thermal hydraulic analyses using tools such as RELAP5 3D, GOTHIC, SAS, or equivalent, with the ability to extend or tailor modeling approaches within these frameworks.
- Strong foundation in thermal fluids and reactor system behavior, including complex thermal hydraulic phenomena relevant to advanced reactor designs.
- Experience in sensitivity analyses and model gap identification that support method development priorities.
- Familiarity with scientific programming and workflow automation (e.g., Python, MATLAB).
- Familiarity with NQA 1 quality assurance for modeling workflows, including documented methodologies, configuration control, and model traceability.
- Strong analytical thinking, clear technical communication, and the ability to support multiple method development efforts in parallel.
- The service provider will possess a high degree of trust and integrity, communicate openly and display respect, and a desire to foster teamwork.
- Travel Required: 0-5%
