Job description

Description

Navarro Research and Engineering is recruiting a Nuclear Engineer (3975) that is remote but with some travel to Idaho Falls, ID. This is a consulting position.

Navarro Research & Engineering is an award-winning federal contractor dedicated to partnering with clients to advance clean energy and deliver effective solutions for complex challenges in the nuclear and environmental fields. Joining Navarro means being a part of an exceptional team committed to quality and safety while also looking for innovative strategies to create value for the client's success. Headquartered in Oak Ridge, Tennessee, Navarro has active programs in place across the nation for DOE/NNSA, NASA, and the Department of Defense.

Position Summary

The Nuclear Engineer will provide analysis and design support for sodium-cooled reactor systems where they are small modular reactors (SMRs), with emphasis on sodium-cooled fast reactor technology. The engineer will apply thermal hydraulics principles, modeling and simulation methods, and reactor systems engineering expertise to evaluate system performance, heat transfer, transients, and safety-related behavior.

This position may be performed remotely and may require travel to Idaho to support conceptual design activities and related technical collaboration.

Responsibilities

• Perform engineering analysis and design for sodium-cooled reactor systems.
• Develop, execute, and evaluate thermal hydraulics models and simulations supporting sodium-cooled fast reactor design and analysis.
• Support reactor systems design activities and evaluate system performance against applicable technical objectives and design criteria.
• Apply computational fluid dynamics tools and/or reactor system analysis codes to assess fluid flow, heat transfer, and system behavior.
• Conduct safety analyses, transient analyses, and heat transfer evaluations for advanced reactor systems.
• Prepare and communicate technical results, assumptions, methods, and conclusions in support of design reviews and conceptual design activities.
• Support nuclear licensing activities, technical design reviews, and advanced reactor development programs, as assigned.
• Collaborate with multidisciplinary engineering teams, clients, national laboratories, reactor vendors, and advanced reactor developers, as applicable.
• Travel to Idaho as needed to support conceptual design activities and other project requirements.

Requirements

• Master's degree or Ph.D. in engineering or a closely related technical discipline.
• Demonstrated experience performing analysis and design for reactor systems.
• Ability to work effectively in a remote environment and travel to Idaho as project needs require.

The candidates should have experience in one or more of the following areas:

• Sodium-cooled fast reactor (SFR) design and analysis
• Thermal hydraulics modeling and simulation
• Reactor systems design and performance evaluation
• Computational fluid dynamics (CFD) and/or system codes used in reactor analysis
• Safety analysis, transient analysis, and heat transfer evaluations
• Nuclear licensing, design reviews, or advanced reactor development programs

Education and Experience

A master's degree or Ph.D. in engineering or a closely related technical discipline is required.

Due to the nature of the government contract requirements and/or clearances requirements, US citizenship is required.
