Nuclear Core Design Engineer information

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.

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

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). This is expanding work in the Instrumentation and Controls Engineering group. Due to this influx of work, Sargent & Lundy has a need for several I&C Engineers.
This is a senior design engineering position that offers a variety of interesting and challenging opportunities in nuclear Instrument and Controls Engineering and will provide an excellent opportunity to advance your career. You will interface with the discipline engineers and designers on the Project Team and with the client to ensure all client requirements are satisfied.
You will work on major process controls engineering projects in the following areas:
  • Digital Systems - PLC, DCS, Touchscreen displays, network switches and control systems
  • Functional Requirement and Procurement Specifications for instrumentation and control systems for nuclear power plants
  • Process instrumentation replacement evaluation reports
  • Prepare documentation for design input for drawing production including cable block diagrams and schematics
  • Interface with vendors and prepare equipment purchase specifications
  • Prepare reports and studies that present technical information in a clear and concise manner to meet client requirements
  • Attend client meetings and perform site walkdowns to ensure the client is satisfied with our work product
  • Provide guidance as a mentor in the development of less experienced nuclear instrumentation and controls design engineer

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:
  • BS degree in engineering from an ABET accredited program
