Job Description:

Remote-Long term contract System Transients Analysis Engineer

Ready to apply Before you do, make sure to read all the details pertaining to this job in the description below.

SystemOne is seeking to contract with a highly capable and motivated System Transients Analysis Engineer who is responsible for analyses using the RELAP5-3D code for both thermal-hydraulics plant-wide and component level transient analysis with application to the TerraPower sodium-cooled reactor program. The successful candidate will support transient analyses for various reactor designs including novel systems. The analyses may also involve use of existing in-house and commercial codes or may involve generation of new code or augmentation of existing code. They will interface with the safety group and other groups to accurately represent the different systems of the plant.

Responsibilities Develop RELAP5-3D models for steady state and transient one-dimensional network hydraulic analyses.
Perform calculations using first principles of heat transfer, fluid dynamics, and thermodynamics to support and validate analysis results.
Perform analysis of reactor normal operations, upset events, emergency events and faulted events to establish design, service, and test loadings and limits.
Perform analysis of plant wide transients for evaluation of operation narratives and design solutions.
Perform multiscale and multidisciplinary neutronics and control analyses involving the thermal hydraulics of sodium, molten salt, and non-condensable fluids.
Integrate with other engineering groups performing aspects of component, system, fuel, and control system design and related thermal-hydraulic testing.
Perform code benchmarking and validation analyses to support code qualification and methodology development.

Key Qualifications and Skills
- B.S. or higher degree in nuclear or mechanical engineering.
- Strong thermal-hydraulic analytical skills with one dimensional hydraulic networks analysis, system codes experience and transient analysis.
- Minimum 2-year experiences with system codes RELAP5 is a must.
- Experiences in safety analysis highly desirable.
- Familiarity with code V&V and associated regulatory requirements.
- Experience with nuclear power plant design or operations a plus.
- Experience with first-of-a-kind or high temperature nuclear reactor design projects is a plus.
- Strong technical writing skills.
- Strong communication skills desired
- The successful candidate will possess a high degree of trust and integrity, communicate openly and display respect, and a desire to foster teamwork
- Actual position starting level and title will be determined based on assessment of qualifications.
