Job description

Idaho National Laboratory is hiring a Fitter to work on our Advanced Test Reactor (ATR) Maintenance team. Our team works a 4x10 schedule located out of our ATR facility with every Friday off. You will perform maintenance and installation of piping, tubing systems, and components.

The Work Matters Here:

The Advanced Test Reactor at Idaho National Laboratory is one of the most unique and consequential facilities in the world. As the nation's most powerful research reactor, ATR drives breakthroughs in nuclear fuel development, materials science, and national security-work that directly shapes America's energy independence and defense capability. The systems that keep ATR operating do not maintain themselves. That is where you come in.

Essential Job Functions and Responsibilities:

• Perform layout, fit-up, and fabrication of piping systems in accordance with engineering drawings, isometrics, and specifications and maintain compliance with applicable codes and standards (e.g., ASME B31.1, B31.3) for piping fabrication and installation.
• Read and interpret blueprints, piping isometrics, and P&IDs to determine fit-up requirements and material needs.
• Fit and align pipe, fittings, flanges, and supports to meet precise tolerance and alignment requirements prior to welding.
• Fabricate and install pipe spools, supports, and hangers for new installations and modifications.
• Perform field measurements and layout for piping runs, ensuring proper slope, alignment, and clearance.
• Select and prepare materials, including cutting, beveling, and threading pipe as required.
• Perform pressure testing, inspection, and quality checks on completed piping systems.
• Inspect, troubleshoot, repair, install, and maintain mechanical/piping and tubing systems and their components.
• Operate shop equipment, test jigs, and use piping/tubing installation/repair/maintenance tools, as well as basic hand and power tools.
• Inspect, troubleshoot, repair, install, and maintain high-pressure/hazardous material and waste systems.
• Inspect, troubleshoot, repair, install, and maintain fire systems, fire hydrants, fire protection fluid systems, air dryers, and heat exchangers.
• Couple and align mechanical/piping,
