Nuclear Core Design Engineer information

What are the key skills and qualifications needed to thrive as a Nuclear Core Design Engineer, and why are they important?

To thrive as a Nuclear Core Design Engineer, you need a strong background in nuclear engineering, reactor physics, and thermodynamics, typically supported by a relevant engineering degree. Proficiency with simulation and modeling software such as MCNP, SCALE, or CASMO, and familiarity with regulatory codes are essential. Strong analytical thinking, attention to detail, and effective teamwork set standout professionals apart in this field. These skills ensure safe, efficient, and regulatory-compliant reactor core designs, which are critical for nuclear plant operation and public safety.

What are some common challenges faced by Nuclear Core Design Engineers during new reactor projects?

Nuclear Core Design Engineers often encounter challenges such as balancing safety requirements with optimal reactor performance during new projects. They must navigate complex regulatory standards, work with interdisciplinary teams, and ensure that their designs account for fuel efficiency, thermal limits, and long-term reliability. Close collaboration with safety analysts, operations staff, and regulatory bodies is essential to address evolving project needs and unexpected technical issues. Staying current with technological advancements and adapting designs to new materials or methodologies is also a key part of the role.

What is the difference between Nuclear Core Design Engineer vs Nuclear Reactor Engineer?

AspectNuclear Core Design EngineerNuclear Reactor Engineer
Primary FocusDesigning and optimizing nuclear reactor cores for safety and efficiencyOperating, monitoring, and maintaining nuclear reactors during operation
Required CredentialsEngineering degree, often with specialization in nuclear engineering, certifications in reactor safetyEngineering degree, nuclear engineering background, reactor operation licenses
Work EnvironmentDesign labs, research facilities, engineering officesReactor sites, power plants, operational control rooms
Industry UsageUsed during reactor design, development, and safety analysis phasesActive during reactor operation, maintenance, and troubleshooting

The main difference is that Nuclear Core Design Engineers focus on designing and optimizing reactor cores before and during construction, while Nuclear Reactor Engineers are involved in the operation and maintenance of reactors once they are active. Both roles require nuclear engineering expertise but serve different stages of the reactor lifecycle.

What does a Nuclear Core Design Engineer do?

A Nuclear Core Design Engineer is responsible for designing, analyzing, and optimizing the arrangement and performance of fuel assemblies within a nuclear reactor core. Their work ensures the reactor operates safely and efficiently while meeting regulatory requirements and power output goals. This involves complex calculations, simulations, and collaboration with other engineers to assess fuel utilization, thermal limits, and overall core behavior during various operating conditions.

Job description

As an emerging leader in nuclear engineering, our startup is developing revolutionary reactor technology to secure safe and abundant energy for future generations.  We are seeking a highly skilled entry-level Nuclear Engineer I/II to join our dynamic team and contribute to the design and development of next-generation nuclear reactors.


The Nuclear Engineer I/II will contribute to the design, analysis, and optimization of advanced nuclear reactor systems. The ideal candidate will have a strong background in nuclear engineering, proficiency with industry-standard design software, and a proactive, self-starting attitude. This role requires innovative thinking, technical expertise, and a commitment to advancing safe and sustainable nuclear energy solutions.

Key responsibilities
  • Design and develop nuclear reactor systems, including core design, thermal-hydraulics, and safety systems, ensuring compliance with regulatory standards.
  • Perform simulations and analyses to optimize reactor performance, safety, and efficiency using industry-standard software tools.
  • Collaborate with multidisciplinary teams, including mechanical engineers, materials scientists, and safety analysts, to integrate reactor designs into broader systems.
  • Conduct risk assessments and safety analyses to ensure designs meet stringent nuclear safety requirements.
  • Prepare technical reports, design documentation, and presentations for internal stakeholders and regulatory bodies.
  • Stay updated on advancements in nuclear technology, materials, and regulations to incorporate cutting-edge solutions into designs.
  • Participate in project planning and scheduling to ensure timely delivery of design milestones.
  • Contribute to research and development initiatives for innovative reactor concepts.  
qualifications
  • Master’s degree in Nuclear Engineering or a related field. Ph.D. preferred but not required.
  • Minimum of 1-2 years of experience in nuclear reactor design, analysis, or related fields within industry or in academic work.
  • Proficiency with nuclear design and analysis software, such as MCNP, SCALE, RELAP5, COMSOL, MOOSE, GOTHIC etc.
  • Familiarity with CAD software for reactor component design.
  • Proficiency in programming languages for data analysis, scripting, or automation of design processes.
  • Knowledge of nuclear physics, neutronics, thermal-hydraulics, and reactor safety principles.
  • Experience with Molten Salt Reactor design preferred.
  • Demonstrated ability to work independently, take initiative, and drive projects to completion with minimal supervision.
  • Excellent written and verbal communication skills for technical documentation and cross-functional collaboration.
  • Familiarity with nuclear regulatory frameworks and safety standards.
  • Knowledge of materials science, particularly related to radiation-resistant materials and high-temperature applications.
  • Familiarity with risk assessments and analysis (PRA, FMEA, PIRT etc.) preferred
  • Familiarity with computational fluid dynamics (CFD) for thermal-hydraulic analysis preferred.
  • U.S. citizenship or permanent residency required.
What we offer
  • Competitive salary with equity options
  • Comprehensive benefits, holiday and PTO schedule
  • Opportunity to shape foundational operations in a groundbreaking nuclear startup.

Fissionaire’s technology is subject to U.S. export control regulations, which require the company to review applicants’ eligibility based on their citizenship or residency status. As part of the application process, candidates will be asked to indicate whether they are a U.S. citizen, green card, lawful permanent resident, asylee, or refugee resident to support this review.
