Senior Engineer, Nuclear Systems Code Developer

Summary

Join Kairos Power as a Senior Engineer supporting KP-SAM Code Development. You will lead KP-SAM IET validation efforts, lead thermal hydraulics or source term development projects, and develop validation strategies. Responsibilities include developing new source term models, maturing existing models, supporting safety analysis, and collaborating with various teams. This role requires a Ph.D. or M.S. in a related engineering field, 10+ years of experience developing nuclear reactor systems code, and deep knowledge of nuclear thermal hydraulics. The position offers competitive compensation, medical, dental, and vision benefits, paid vacation, and a 401(k). Some travel may be required.

Requirements

• Ph.D. or M.S in nuclear engineering, mechanical engineering, mathematics, computer science, or related engineering field
• 10+ years of work and/or academic experience developing a nuclear reactor systems code
• Deep knowledge of nuclear thermal hydraulics and wide knowledge of nuclear reactor systems
• Having capability to independently create new TH models, implement models into actual systems code, and perform verification & validation
• Experience in software development and coding skills, such as C++ and Python programming
• Familiar with scientific computational environment and tools such as version control software such as Git, Github, latex,  Linux or Mac OS environment

Responsibilities

• Lead KP-SAM IET validation efforts by working with junior code developers
• Lead selected thermal hydraulics or source term development projects, and develop validation strategy by collaborating with other KP-SAM team members, testing teams and ANL SAM team
• Provide support for Safety Analysis team and Licensing Team
• As a KP-SAM team member, help other normal code maintaining and SQA related tasks, and support additional validation and analysis tasks
• Develop new source term models into KP-SAM through the full stage of cycle, including literature review of the relevant physics, developing models, implementing the models into KP-SAM, developing testing cases, performing sensitivity and uncertainty analysis, writing documentation, and proposing validation test ideas
• Mature existing source term models through demonstration testing, review, validation, and actual safety analysis application
• Help the Safety Analysis team develop source term analysis input models
• Collaborate with the risk analysis team, salt chemistry team, tritium team, and engineering design teams to help the Source Term Method Lead address source model related issues
• Interface with testing teams to sponsor source term validation tests and perform validation
• Assist in normal software maintenance and updates with ANL SAM code
• Publish internal engineering reports and external journal or conference papers
• Other duties as assigned

Preferred Qualifications

• Experience with any systems analysis codes such as SAM or RELAP is highly preferred
• Experience with model development with DOE MOOSE framework, is highly preferred
• Capability to develop complex systems models for real problems
• Proven capability to perform strict verification and validation; past experiences in IET validation is highly desired
• Knowledge and experiences in numerical methods, such as JFNK method, high order methods in time or space (finite volume or finite element method)

Benefits

• Competitive compensation packages
• Medical, dental and vision benefits for employees and their dependents
• Paid Vacation
• 401(k) and pre-tax health insurance, dependent care, and commuter benefits (FSA)
