0System One has a remote contract need for a System Transients Thermal Hydraulics Engineer to support our client in the nuclear industry. This is a 6 month contract with possibility for extension.The System Transients Thermal Hydraulics Engineer is responsible for both thermal-hydraulics plant-wide and component level transient analysis with application to our client's sodium-cooled reactor program. The successful candidate will support transient analyses for various reactor designs including novel systems. The analyses may 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 and apply thermal-hydraulic analysis methods, including 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 as defined in the ASME BPVC Section III to establish design, service, and test loadings and limits.
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.
Required Qualifications and Skills
M.S. or PhD in nuclear or mechanical engineering.
Strong thermal-hydraulic analytical skills with one dimensional hydraulic network analysis, system codes experience and transient analysis.
Substantial (5-10 years) experience with RELAP, SAS4A/SSYS-1, GOTHIC, or other system code.
Familiarity with code V&V and associated regulatory requirements.
Experience with nuclear power plant design or operations a plus.
Knowledge of design approach under ASME Boiler Code Section III a plus.
Experience developing new analytical methods highly desirable.
Experience with first-of-a-kind or high temperature nuclear reactor design projects is a plus.
