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.

What are the key skills and qualifications needed to thrive as a nuclear core design engineer?

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.

Job description

Description
Nuclear Power is a carbon-free energy source. Our nuclear power generation clients are digitizing their existing power plants and building new nuclear power plants, small modular reactors (SMR) due to the increasing demand for electric power. This is expanding our work in the Instrumentation and Controls Engineering group. Due to this influx of work, Sargent & Lundy has a need for additional I&C Engineers. Our new offices at 2 North Central Ave., Phoenix are more centrally located.
Responsibilities:
Nuclear Power is a carbon-free energy source. We offer you the opportunity to utilize and expand your academic background in engineering by digitizing nuclear power plants:
  • You will work on a multi-discipline engineering team involved in nuclear power plant Instrumentation and Control projects. These projects are a synergistic integration of electrical, computer and mechanical engineering along with control theory.
  • You will work with electronic process sensors, digital controllers, network topology, touchscreen displays, pumps, valves, heat exchangers, steam turbines and reactors.
  • You will prepare specifications for the procurement of instrumentation and controls equipment as well as engineering calculations.
  • Through mentoring, classroom-style technical sessions, and on-the-job training, you will increase your knowledge and skills in your engineering discipline.
  • You will also have the opportunity to travel to client and vendor offices for design reviews and to plant site locations for project coordination and field verification of designs.
  • Support station outage activities as required

This position is based on a hybrid work schedule and will require in-office work 3 days per week.
Qualifications
We do not sponsor employees for work authorization in the U.S. for this position.
Essential Skills:
  • A BS or MS degree in Electrical, Mechanical, or Chemical Engineering (from an ABET accredited program) with a strong academic background and coursework in analog and digital control systems is required
  • 3 or more years of experience in design engineering for nuclear power plant control systems
  • Excellent written and verbal communication skills

Valued but not required skills and experience:
  • PE license

AI & Automation at Sargent & Lundy
In this role, we expect people to be willing or able to solve problems using modern tools:
  • You are expected to take engineering problems from issue to solution using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs.
  • Many engineers in these roles build or use automation to create calculations, summarize technical documents, or draft design documentation, including appropriate use of agentic AI tools, with strong engineering judgment and verification of results.
  • Programming or scripting (e.g., Python, MATLAB, advanced Excel) to automate calculations, design checks, reporting, or data transformation is valued but not required.
  • We also value additional learning, such as a minor, certificate, or other training in Computer Science, Artificial Intelligence, Software Engineering, or related fields that helps you apply automation or agentic AI to real engineering problems.
