ATR Engineering Intern - Summer 2027- Pressure Relief & PM Analysis

Idaho National Laboratory•Idaho Falls, ID
•Onsite

About The Position

Reporting to a Senior Manager within the Experiment Engineering group, the ATR Engineering Intern will support the Advanced Test Reactor (ATR) by developing and documenting the technical basis for pressure relief valves and contributing to preventative maintenance (PM) interval justification. The role is intended for students interested in applying engineering fundamentals to nuclear facility systems, working with technical requirements, and supporting safe, reliable operations. The intern will review design documentation, system drawings, operating requirements, and historical maintenance data for pressure relief valves; help develop technical bases for valve setpoints, sizing, code requirements, and system interfaces; and support PM Basis development and interval justification. The role also includes analyzing performance trends, work orders, and component failure data; assisting with walkdowns, equipment verification, and configuration management checks; preparing technical documentation and calculation updates; participating in meetings and safety reviews; reviewing and preparing portions of experiment safety analysis documentation; and becoming familiar with experiment irradiation in ATR. The team works onsite at the Advanced Test Reactor campus on a 4x10 schedule. Internship start date and duration vary based on project and student availability. Course credit may be available.

Requirements

  • Be enrolled full time as an undergraduate student in an ABET-accredited engineering program at an accredited college or university. Listed fields include Mechanical, Nuclear, Industrial, Chemical, Reliability, Systems, or Materials Science & Engineering.
  • Have a minimum overall GPA of 3.0.
  • Be authorized to work in the U.S., including through CPT or OPT.
  • Have an interest or experience with pressure boundary systems, ASME code concepts, or technical calculations.
  • Be able to read engineering drawings and interpret technical requirements.
  • Have clear and organized technical writing skills.
  • Provide a current resume or CV, unofficial transcripts including current and completed degree programs, and current class schedule and number of credits.

Nice To Haves

  • Coursework in fluid mechanics, thermodynamics, or mechanical component design.
  • Strong analytical skills for evaluating maintenance and reliability data.

Responsibilities

  • Review design documentation, system drawings, operating requirements, and historical maintenance data for pressure relief valves.
  • Develop and refine the technical basis for valve setpoints, sizing, code requirements, and system interfaces.
  • Support PM Basis development, including interval justification.
  • Analyze historical performance trends, work orders, and component failure data.
  • Support engineers with walkdowns, equipment verification, and configuration management checks.
  • Prepare technical documentation, calculation updates, and engineering memos.
  • Participate in team meetings, safety reviews, and discussions related to system reliability and regulatory compliance.
  • Review and prepare portions of experiment safety analysis documentation.
  • Become familiar with the process of irradiating experiments in the Advanced Test Reactor.

Benefits

  • Course credit may be available for the internship.
