Role Description

Thermal-Hydraulics Engineers at Oklo are responsible for analyzing fluid flow and heat transfer within a reactor and associated systems. This work includes engineering analyses of thermal-fluid dynamics, clear and thorough documentation of the analyses, as well as interfacing with design teams. A Systems Thermal-Hydraulics Engineer will contribute to the development, qualification, and validation of systems-level models of steady-state and transient thermal-hydraulic reactor behavior.

• Modeling thermal-hydraulic systems using codes such as SAS4A/SASSYS-1, SAM, or GOTHIC
• Developing systems-level analyses to analyze coupled neutronic and thermal-hydraulic behavior at steady-state and during transients
• Developing and utilizing analysis methods that efficiently and effectively build confidence in a design
• Automation, verification, and validation of modeling and simulation tools in support of analyses
• Collaborating cross-functionally to define design requirements, and providing technical feedback to quick-iterating design teams
• Document work using modern tools and techniques, and write well-written, thoughtful technical reports

Qualifications

• Bachelors, Masters, or PhD in a technical field, such as nuclear, mechanical, or aerospace engineering
• Proficiency with thermal-hydraulics (thermal fluids) analysis methods
• Core competencies in heat transfer, fluid dynamics, and thermodynamics first principles
• Experience with systems-level thermal fluids analysis codes, such as Flomaster, GOTHIC, or TRACE
• Experience with data processing (e.g., pre-processing, post-processing, scripting)
• Fluency with Python

Requirements

• Experience with reactor transient analysis methods
• Experience with advanced reactor systems codes such as SAS4A/SASSYS-1, SAM, and RELAP
• Experience with qualification and validation of analyses
• Experience with nuclear engineering principles and multi-physics analysis methods for engineering applications, particularly as they relate to advanced reactors
• Competency with modern software engineering practices and programming languages
• Experience with CI/CD computing environments

Benefits

• Salary: $73,000-$157,000
• Flexible time off
• Equity
• Competitive pay
• 401k
• Health insurance
• FSA
• Flexible work hours
• Other benefits

Company Description

Oklo Inc. is developing fast fission power plants to deliver clean, reliable, and affordable energy at scale; establishing a domestic supply chain for critical radioisotopes; and advancing nuclear fuel recycling to convert nuclear waste into clean energy. Oklo was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant, was awarded fuel material from Idaho National Laboratory, and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission. Oklo is also developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and U.S. National Laboratories.
