ATR Millwright

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 rotating equipment and mechanical systems that keep ATR running demand a level of precision that not everyone can deliver.

That's where you come in.

As a Millwright Mechanic
, your precision isn't just a professional standard, it's a mission requirement. The work you do every day helps keep critical research online, supports U.S. nuclear energy policy, and contributes to national security in ways that extend far beyond the facility fence line. If you take pride in doing precision work right the first time and want to be part of a crew that feels the same way, the ATR Complex is worth a hard look.

Your core focus is the precision installation, alignment, and maintenance of rotating equipment and mechanical systems across the ATR Complex:

• Install, align, and maintain centrifugal and positive displacement pumps, motors, gearboxes, couplings, and shafts
• Perform precision shaft and laser alignment of rotating machinery
• Use micrometers, dial indicators, feeler gauges, and calibrated torque tools
• Use vibration analysis equipment to evaluate rotating equipment condition
• Dismantle and reassemble complex mechanical components - gearboxes, couplings, shafts, and related systems
• Remove, inspect, and install all bearing types - sleeve, roller, ball, thrust, and journal
• Replace mechanical, O-ring, and lip seals; replace pump packing
• Lubricate equipment, collect oil samples, and perform vibration monitoring
• Balance fans and perform predictive maintenance on rotating equipment
• Maintain hydraulic and pneumatic systems
• Interpret OEM manuals, schematics, and technical documentation
• Participate in work planning, material procurement, and man-hour estimating
• Mentor and provide on-the-job training to less experienced craftsmen
• Actively participate in all company safety programs including VPP, ALARA, and EST
• Complete the ATR Mechanic Qualification Card and all other required training as directed
• Perform other duties as assigned by management

• High School diploma or GED plus 5 years of applicable experience in industrial mechanical systems with an emphasis on rotating equipment and millwright work, or a 2-year vocational/technical training plus 3 years of experience, or a recognized trade apprenticeship completion plus 2 years of applicable experience
• Proficiency with precision instruments - micrometers, calipers, laser alignment tools, and dial indicators
• Familiarity with vibration analysis and predictive maintenance techniques
• Ability to read and interpret blueprints, schematics, and OEM manuals
• Working knowledge of LOTO, PPE, confined space entry, and industrial safety standards
• Ability to obtain Radiological Worker Qualification within 45 days of hire
• Valid state driver's license
• Ability to obtain and maintain a DOE "L" security clearance within 1 year of hire, which requires U.S. citizenship.

• Radiological Worker II (Rad Worker
  2): Required for work in radiological areas throughout the ATR Complex.
• Respirator
  
  Qualification:
  
  Required for work in areas with potential airborne hazards.
• Overhead Crane Inspector: Required for inspection and oversight of crane operations.

• 5+ years of journeyman-level millwright experience in an industrial or commercial setting.
• Experience in nuclear, government, or other highly regulated industrial environments.

While performing the duties of this classification, the employee is frequently required to stand, walk, sit, stoop, kneel, bend, climb ladders, work at heights, and in confined spaces. The job requires hand/finger dexterity to keyboard or type, handle materials, manipulate tools, and reach with hands and arms. The job requires operation of job-related equipment and driving a vehicle. The employee must occasionally lift and/or move up to 50 pounds.

Sufficient visual acuity and hearing capacity to perform the essential functions and interact with the public is required. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

The work environment includes an office, buildings, and a field environment. The field environment may include exposure to adverse weather, working in high traffic areas, potential exposure to radiation work, hazardous chemicals/waste, and noisy and/or loud equipment. Field work may include working with hazards involving the use of ladders, stairs, confined spaces, power tools and equipment which subjects the employee to mechanical and electrical hazards, moving vehicles, and heavy equipment.

Varied work locations may expose incumbent to extreme temperatures and UV (sun)…
