About the Job

Requirements

  • A minimum of a bachelor's degree in Nuclear, Mechanical, or Chemical Engineering, or a related discipline, from an accredited four-year college or university is required.
  • A minimum of 8 years of full-time, directly relevant engineering experience is required.
  • Experience implementing engineering design processes for subchannel thermal-hydraulics, transient analysis, and related safety analysis is required.
  • Experience with RELAP5 is required.
  • The candidate must be eligible to work under Department of Energy 10 CFR Part 810.
  • The candidate must understand and communicate clearly using a phone, personal interaction, and computers.
  • The candidate must be able to learn new job functions, quickly comprehend and understand new concepts, and apply them accurately in a rapidly evolving environment.
  • The candidate must be able to travel nationally and locally using common forms of transportation.
  • The candidate must understand and implement quality assurance regulations, standards, and guidelines, including 10 CFR 50 Appendix B, 10 CFR 21, and ASME NQA-1.

Responsibilities

  • Prepare and verify VIPRE subchannel analyses, including critical heat flux predictions and margin evaluations, in accordance with approved methods.
  • Prepare and verify RELAP system-level thermal-hydraulic evaluations, including loss-of-coolant accident, non-loss-of-coolant-accident transients, and design-basis evaluations, in accordance with approved methods.
  • Evaluate whether system designs, operating functions, and engineered features perform required safety functions in alignment with licensed methods and design-basis requirements; recommend design modifications that preserve safety margins while maintaining system performance objectives, operational practicality, and integration with the overall plant design.
  • Lead cross-functional thermal-hydraulic reviews for reload safety analyses, plant design changes, operational concepts, and licensing deliverables; identify margin sensitivities and cross-discipline interface impacts.
  • Support development and maintenance of licensed thermal-hydraulic methods and associated implementing analyses; maintain thermal-hydraulic modeling standards, evaluate method applicability ranges, and advise on code and model updates.
  • Participate in applying and translating licensed methods into alternate regulatory frameworks for international customers, including adapting thermal-hydraulic methodologies to country-specific regulatory expectations.
  • Work collaboratively within the Nuclear Fuels organization to manage design and analysis interfaces, including those with core and fuel design, subchannel thermal-hydraulics, and transient analysis.
  • Provide technical leadership within Thermal Hydraulics, mentor junior engineers, and lead complex analysis tasks in areas of expertise.
  • Contribute to technical development of licensing technical or topical reports, license applications, and other licensing documentation, and participate in licensing interactions with the government regulator in areas of technical responsibility.
  • Prepare and verify engineering reports, calculations, studies, system descriptions, requirement specifications, and other design documents, particularly those related to subchannel and system thermal-hydraulics.
  • Work on tasks in multiple and diverse areas.
  • Develop innovative solutions to multifaceted technical challenges requiring original thinking, multiphysics reasoning, and navigating uncertainty; independently frame problems, propose solution strategies, and execute analyses with minimal oversight.
  • Perform other duties as assigned and flexibly support changing organizational priorities, including urgent analysis needs, cross-functional reviews, technical troubleshooting, and special studies.
  • Perform the essential duties and responsibilities efficiently and accurately, with or without reasonable accommodation, without causing a significant safety threat to self or others.

Desired Qualifications

  • An advanced degree in Nuclear, Mechanical, or Chemical Engineering is desirable.

About the Company

NuScale

Develops and licenses small modular reactors

NuScale Power develops small modular reactors (SMRs) and licenses the technology to utilities, industrial users, and governments. Its flagship NuScale Power Module (NPM) is a 77 MWe integral pressurized water reactor that is factory-fabricated, uses natural circulation, and combines the reactor vessel, steam generator, and pressurizer in one unit. A VOYGR plant can house up to 12 NPMs for up to 924 MWe, enabling incremental deployment; safety relies on passive cooling that can self-shutdown without power or operator action. The company partners with Fluor and Doosan and targets projects for electricity, district heating, desalination, and hydrogen production, including international opportunities.
