Senior Nuclear Facility Engineer

Job Summary

The Reactor Vessel Auxiliary Systems team is seeking a highly motivated Senior Engineer to join the growing Reactor Systems department where you will have the opportunity to work directly on the design, integration, and assembly of the structures, systems, and components (SSCs) within the reactor cavity in a first-of-a-kind FHR.

In this role, you will manage and coordinate the detailed layout of reactor cavity components including routing of fuel, salt, and gas lines from the reactor vessel through the bio-shield, locating remote handling accessible instrumentation, and standardizing common components and features. The position requires a strong aptitude for mechanical design, systems engineering, and high temperature components under irradiation. You will regularly interface with multi-disciplinary teams including nuclear design, civil structures, remote handling, reactor coolant auxiliary systems, reactor systems, safety analysis, instrumentation & controls, and plant design integration. You will work closely with these teams to implement component and instrumentation standardization, collaborate on SSC design, and develop a cavity layout that meets safety analysis, construction, and maintenance requirements for FHR demonstration reactors.

Responsibilities

• Own and manage the 3D layout and spatial integration of all components within the reactor cavity including reactor vessel and support systems, instrumentation, shielding, and maintenance interfaces.
• Coordinate with mechanical, civil, and I&C design teams to define spatial, thermal, and functional interfaces between the reactor vessel, cavity systems, and bio-shield.
• Lead design integration reviews to ensure structures, systems, and component designs are compatible and accessible for installation and maintenance.
• Develop and implement standardized layouts, component interfaces, and remote maintenance connection strategies to streamline manufacturing, assembly, and maintenance operations.
• Regularly interface and communicate component requirements with other disciplinary teams including nuclear design, reactor systems, reactor coolant auxiliary systems, safety analysis, remote handling, and manufacturing.
• Perform design verification and validation activities to ensure system performance meets functional and safety requirements.
• Participate in hazard and failure analyses (HAZOP, FMEA, FTA) and incorporate safety insights into design iterations.
• Contribute to configuration management by maintaining design baselines, revisions.
