Job summary

Subcritical Systems Inc. in Austin, TX, seeks nuclear/mechanical thermal-hydraulics engineers to lead or support design, simulation, prototyping, and procurement of thermal-hydraulic systems such as primary Pb loop, passive decay heat removal, and test loops.

You will collaborate with cross-functional teams to optimize core thermal-hydraulics while contributing to regulatory submissions and milestone tracking in a fast-paced startup.

Qualifications

• M.S. preferred or B.S. in Mechanical Engineering or similar field.
• Experience in nuclear system thermal-hydraulics design and/or modeling.
• Experience using CFD code(s) to model heat transfer in nuclear systems.
• Record of technical accomplishment through publications and presentations.
• Export control restrictions limit us to candidates who are U.S. citizens or U.S. permanent residents (green card holders).

Responsibilities

• Serve as an integral member of the subcritical fission system team responsible for designing, prototyping, and ultimately constructing the subcritical assembly.
• Lead or support design and modeling of one or more thermal-hydraulic systems: primary Pb loop, passive decay heat removal system, intermediate cooling loop and Pb test loop.
• Perform design, FEA and CFD simulations of cooling systems and components.
• Study available component options (pumps, heat exchangers, etc.) for adoption in the baseline design.
• Lead or support design, construction and operation of a scaled Pb loop to test scaled prototype components. Work with materials scientist staff to incorporate erosion and corrosion testing in the scaled Pb loop.
• Develop and document design, hardware specifications, interface requirements and procurement documents.
• Work closely with the nuclear engineering team to optimize the core design from a thermal-hydraulics standpoint.
• Work closely with other engineering team members responsible for designing the subcritical core and core vessel internals to ensure systems meet performance requirements.
• Work with the leadership team on developing & tracking key company technical milestones, ensuring delivery of results within aggressive timelines in a complex, fast-paced environment.
• Document work in written reports, presentations, and regulatory submissions.
