Job Description
Job Title: Natrium 615 - Thermal Hydraulic Software Analysis Engineer (TP-PR-)
Location: Remote or Bellevue WA
Duration: 12 months (high possibility of multiple 12 months extension)
Rate Offered: $56 - $95/hr. on W2
Full Time: 40 hrs/week
Key skills: experience with python-based computational tool development and maintenance is highly required. Experience with subchannel analysis codes such as COBRA, SAM, Pronghorn, etc. and/or system thermal hydraulics analysis codes such as RELAP5-3D, TRACE, etc. is preferred
Job Description:
TerraPower, LLC. is seeking a Contractor with a highly motivated Thermal Hydraulic Software Analysis Engineer to support the computational thermal-hydraulic analysis of the reactor core for the sodium-cooled Natrium Reactor program. Reporting to the Manager, Core Thermal Hydraulics Methods & Analysis for System Thermal Hydraulics, you will refine core assembly designs and evaluate their thermal-hydraulic behavior under various conditions in advanced nuclear reactor system.
Tasks
Perform thermal hydraulic analysis and engineering calculation/assessment of nuclear reactor core components and structures in exploration of reactor architecture options including component selections, configurations, and sizing in support of the design of Natrium demonstration reactor system using in-house thermal-hydraulic software, computational fluid dynamic software, and hand calculations
Work with cross-disciplinary teams to analyze the thermal and mechanical design considerations for the reactor and its components
Provide technical presentations on analyses performed to the broader team.
Prepare informal and formal reports to document findings and make reasoned recommendations, and report to core thermal hydraulic team manager/lead
Key Qualifications and Skills
B.S., M.S., or Ph.D in Mechanical, Nuclear, or other relevant technical Engineering area from an accredited university
Minimum of 6+ years of experience in the relevant industry with a B.S. degree, or 3+ years with an M.S or Ph.D. degree with demonstrated ability to perform the thermal-hydraulic analysis of nuclear reactor core components for simulation-based design
Strong background in nuclear thermal-hydraulics analysis, with demonstrated expertise in evaluating and performing engineering calculations related to the flow distribution, pressure drop and heat transfer in nuclear reactor cores, as proven through university research, publications, and/or work experience
Demonstrated expertise in Python programming for nuclear thermal hydraulic software development, maintenance, and modeling and simulation. Proficient in C++ programming language and numerical solver development a plus
Proven problem-solving skills and a willingness to apply those skills to a variety of engineering problems.
Knowledge and experience in liquid metal thermal-hydraulics or experience with nuclear reactor system analysis codes highly preferred
Experience in nuclear industry preferred
Experience working with high-performance computing (HPC) environments preferred
Experience in Software Quality Assurance (SQA) program and Nuclear Quality Assurance (NQA-1) standards highly preferred
Must have excellent verbal and written communication skills due the NQA-1 environment and requirements for formally documenting calculations
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
