The Role

We are seeking a Nuclear Engineer specializing in thermal hydraulics analysis and related competencies to support the deployment of new nuclear facilities across multiple projects and client environments for new reactors and novel nuclear facilities under DOE , NRC, and international regulatory frameworks.

What You’ll Do

Generate thermal hydraulic models (i.e., create base decks) of nuclear reactor primary circuits (and portions of steam generators), validate such models, and utilize such models to enhance the normal operational designs and confirm accident response of new nuclear reactors. Scaling, constructing, and running thermal hydraulic test facilities under nuclear quality assurance standards as needed to support model accuracy. Participate in phenomenon identification and ranking table (PIRT) panels.

Support the creation of licensing documentation associated with the results of thermal hydraulics analysis. Travel to support testing facilities or industry conferences up to 20%.

This role may involve computational fluid dynamics (CFD), heat exchanger design optimization, system level analysis, best estimate plus uncertainty (BEPU) analysis, thermal hydraulic stability modeling, severe accident modeling (beyond design basis), subchannel analysis, critical heat flux, software quality assurance, and conservative deterministic safety analysis (NUREG-0800 Chapter 15 small and large break LOCA). Applicants capable of doing a larger percentage of these inter-related tasks to accomplish complex nuclear reactor design tasks independently will be given priority.

Qualifications

  • BS, MS, or PhD in Nuclear Engineering, Mechanical Engineering, or related field
  •  
    Proficiency in a number of thermal hydraulics related software RELAP, TRACE, GOTHIC, Ansys Fluent, MELCOR, MAAP, STAR-CCM+, or similar nuclear specific software. The ability to document and defend your work. The ability to mentor junior personnel.
  • Four years of relevant thermal hydraulic experience (at least two years of which were in nuclear industry specific applications that interfaced heavily with DOE, NRC, or similar). 15+ years of experience in nuclear specific thermal hydraulics related work required for higher end of the pay range.
  • Experience modeling light water reactors and exotic advanced reactor fluids (e.g., molten salt, lead, sodium, etc) is strongly preferred. But experience with only one fluid is acceptable.

Why This Role

  • Exposure to multiple novel reactor programs and technologies.
  • Opportunity to impact economic, safety, and licensing from early design onward.
  • Competitive compensation and strong benefits

Benefits

Competitive salary • 401(k) with match • Health, dental & vision insurance
