GNFE Intern

2026 Poland Global Nuclear Fuel Engineering Intern Program 

Location: Poland 

Are you interested in being part of an innovative team that supports Westinghouse’s mission to provide clean energy solutions? At Westinghouse, we recognize that our employees are our most valuable asset, and we seek to identify, attract and recruit the most qualified talent while recognizing and encouraging the value of diversity in the global workplace. Westinghouse is seeking 2026 Fall/Winter Interns for Global Nuclear Fuel Engineering. 
The internship will take place in the Krakow, Poland office, with business trips to the US or Sweden, depending on team allocation. 
 
  

 Your Day-to-Day:  
  

General: 

• Develop expertise in the design, construction, operation, and decommissioning of nuclear power plants. 
• Grow and develop extensive technical expertise on international nuclear markets. 
• Work in teams to resolve critical issues impacting the construction and operation of nuclear power plants. 
• Develop and maintain an effective business relationship with Westinghouse customers. 
• Perform tasks and activities specific to one of the following Global Nuclear Fuel Engineering departments. 

Core Engineering: 

• Perform standard nuclear design reload calculations by using calculation note templates, following METCOM, guidance from previous cycle calc notes, and consulting with co-authors, functional leads, and mentors. 
• Interpret the results and work with an independent verifier to produce an archived document in PRIME. 
• Perform nuclear design calculations for Westinghouse plant designs, including Reload Safety Analysis Checklist calculations, Nuclear Design Report calculations, and Startup calculations. 

Nuclear Design: 

• As an intern working for the Nuclear Design group, you will participate in general tasks related to nuclear and core design analyses. You might also be involved in feasibility studies, or smaller methodology related projects. For this internship, we see that you are close to finalizing your Master of Science degree in nuclear, engineering, physics or similar. 

Fuel Engineering Technologies: 

• Create and improve methods & software tools for used analysis & design of nuclear fuel 
• Implement automated software testing and quality assurance tools to improve accuracy of Westinghouse codes and methods. 
• Utilize new statistical tools/modeling to benchmark plant measured to predicted data to refine Westinghouse Software & Methods 
• Apply Westinghouse Nuclear Fuel analytical tools for new plant and fuel designs. 

EMEA Fuel Engineering: 

• Mechanical Design 
• As an intern at the department of Mechanical Design, your task will be to support the modeling of 3D models of Fuel Assemblies and internal Components in the CAD system CREO as well as create drawings. 
• You will also support the team with Product Specifications, that is an input to our fuel fabrication at our fuel factory. 
• The department of Mechanical Design produces a high number of technical reports every month, where you will be a contributor. 
• For this internship, we see that you have previous experience of 3D-modelling, not necessarily CREO. 

Product Engineering: 

• Provide engineering design and analysis for nuclear power plants and products, including fuel manufacturing, spent fuel management, service and maintenance, instrumentation and control, and training. 
• Interface with customers, vendors, and other internal functional groups on an engineering level to obtain information necessary to perform work assignments. 
• Plan and schedule work to meet assignment requirements. 
• Mechanical and Thermal Hydraulic design and analysis of Nuclear Fuel & Components. 

Who You Are:  

• As a successful candidate, you will bring the following to the team:  
• Pursuing a Bachelor's degree or Master’s degree Nuclear Engineering, Mechanical Engineering, Computer Science/Engineering, required. 
• Minimum of 3.0 GPA (on 4.0 scale) 
• Should be over 18 years of age 
• EU citizen 
• Needs to be fluent in English and Polish 
• Ability to work for 5-6 months from 1st September 2026 – 28th February 2027 
• Ability to work a minimum of 40 hours per week (8h/day) 
• Ability to obtain J-1 Visa (not required for EMEA Fuel Engineering) 
    

To apply to our Summer Internship Program, please provide the following information:  

• CV 
• Copy of academic performance record  
• A 1500-word essay (+/- 10%)
  applicants need to choose only one essay topic to apply for the internship within GNFE:

1. topic:  Describe the fuel life cycle and how the nuclear design affects it. 
2. topic: Analyze reactor operation goals and constraints, highlighting neutron physics, heat transfer and fuel performance, or provide an in-depth study of a single aspect. 
3. topic : Applications of AI and Machine Learning in the Nuclear Fuel Industry – opportunities, challenges, and how would you implement these technologies?
