What is the difference between Internship Nuclear Engineering Internships vs Nuclear Engineering Technician Internships?

AspectInternship Nuclear Engineering InternshipsNuclear Engineering Technician Internships
Required CredentialsTypically pursuing or holding a bachelor's degree in nuclear engineering or related fieldOften pursuing or holding an associate degree or technical certification in nuclear technology
Work EnvironmentResearch facilities, laboratories, or nuclear power plants under supervisionOperational nuclear plants, testing labs, or maintenance environments
Employer & Industry UsageUsed by universities, research institutions, and nuclear power companies for trainingCommonly used by nuclear power plants and technical service providers for technical support

Internship Nuclear Engineering Internships focus on research, design, and development in nuclear engineering, often requiring a bachelor's degree pursuit. In contrast, Nuclear Engineering Technician Internships emphasize hands-on technical support, maintenance, and operational tasks, typically requiring an associate degree or technical certification. Both roles provide valuable industry experience but differ in educational requirements and work focus.

Job description

About the Role

As a member of the nuclear engineering team, you will become the responsible engineer for a key component of the Antares reactor design such as reactivity controls and instrumentation, radiation shielding, fuels, materials, thermal hydraulics, safety, or licensing. The ideal candidate has a mix of industry and academic experience, and has worked in a team-oriented environment to mature nuclear concepts. While you may have a specialty, you’re not afraid to operate as a generalist in a growing organization.

Roles and Responsibilities
  • Assist with neutronics modeling and simulations using MCNP, Serpent, or SCALE
  • Support Multiphysics analyses (thermal-hydraulics, heat transfer, structural mechanics)
  • Participate in experimental validation of simulation results
  • Collaborate with senior engineers on iterative design tasks
  • Contribute to documentation and regulatory reporting
  • Participate in hardware demonstrations and prototype testing
Basic Qualifications
  • Bachelor's degree in Nuclear Engineering or related technical field
  • Familiarity with neutron transport software (MCNP, Serpent, SCALE)
Preferred Skills & Experience
  • Familiarity with Python or similar programming language
  • Coursework or internships involving Multiphysics modeling
  • Interest or experience in microreactors, heat pipe cooled reactors, or other advanced reactors
  • Exposure to fast-paced project environments
  • Proven ability to quickly learn new technical concepts
  • Strong communication skills
Pay Ranges

Nuclear Engineer I: 120k-135k

Nuclear Engineer II: 135k-165k

Your actual level and base salary will be determined on a case‑by‑case basis and may vary based on the following considerations: job‑related knowledge and skills, education, and experience.
