Our team of nuclear experts includes personnel with backgrounds from both the construction and operations sides of the nuclear industry.

Every component in every plant has a finite lifespan.

Over the last three decades, Barnhart has built an impressive nuclear project resumé. Our team of nuclear experts includes personnel with backgrounds from both the construction and operations sides of the nuclear industry. Barnhart's experience has brought the kind of innovative design and execution that makes money in reducing critical path during outages and improving ALARA in handling components in containment.


The unique nature of nuclear power plants presents opportunities:

  • RPV closure head handling
  • Spent fuel pool handling crane replacements and repair support
  • Replacement of fully-assembled main transformers and component replacements such as MSR units
  • Feedwater heaters and condenser modules all demand custom solutions
  • Once the tools are complete, Barnhart offers personnel experienced in operating custom equipment in the nuclear power environment


Life extension, uprates and major maintenance require the handling of major components within the plants. To perform this work during planned outages, a thorough knowledge of both major construction techniques, as well as the demanding requirements of nuclear protocol, are required. Barnhart has developed unique tools and methods to perform the movement of major equipment such as:

  • RPV closure heads
  • Steam generators
  • Pressurizers
  • Feedwater heaters
  • Condensers

This experience offers operators the peace of mind knowing that Barnhart will meet and exceed expectations for schedule, safety and ALARA. Clients can be certain they have chosen a company that knows the way through the nuclear environment.



Rigging supervision, lift planning, site transportation services, crane services and more can be provided through our team of professional supervisors, engineers and project managers. The expertise of Barnhart helps insure the safety, quality and timely completion of plant outages. Additionally, we are often called upon to participate in the "Readiness Planning" of various operating plants. These plans serve to limit downtime during emergency outages by having in place engineering, rigging plans, transportation surveys and custom tools associated with critical components such as transformers, reactor coolant pumps and turbine rotors.


Barnhart is a leader in the handling of major components associated with nuclear plant decommissioning. We minimize the cost of erecting and testing the handling equipment. This is the distinguishing mark of a Barnhart project. Analysis of existing structures, modular lifting equipment and clever rigging systems minimize risk and improve the ALARA associated with these difficult rigging projects.

Contact us today and let us find the right tool for you.



Experience and certification for hazmat service, Barnhart brings a working knowledge to handling over-the-road trucking of critical equipment associated with the nuclear power production. Movement of reactor coolant pumps, turbine rotors and other components receive the attention of a professional team that understands the needs of the industry. Barnhart's Heavy Lift Terminal in Memphis serves as a transfer point for items bound for the decontamination and waste processing facilities of RACE and Duratek.



Barnhart provides warehousing services to support the Pooled Inventory Management (PIM) program administered by Southern Company. The PIM program is a mechanism for nuclear plant owners to jointly procure and store spare generating equipment. The emergency equipment is useable by two or more operators and is stored and maintained centrally at the Barnhart facility in Memphis. Permanent PIM management reside at the storage facility coordinating the maintenance and handling of the emergency equipment by Barnhart personnel.

Barnhart also offers a traditional heavy component storage of major machinery such as turbines, generators and transformers. The storage facility is located on the Mississippi River serviced by Barnhart's 1,250 derrick crane with site rail access to four Class I railroads.

The Barnhart Advantage

Access to Massive Inventory

Barnhart gives you access to one of the largest platform trailer inventories in the world. This can mean a quicker response, lower mobilization cost and less chance of delays.

Built-in Safety

All of Barnhart's processes, as well as our custom designed tools, are designed by our engineers with the optimum safety standards in mind. Efficiency and speed are useless attributes without safety.

Deep Inventory

With hydraulic cranes for hire from 18 to 600 tons, crawler cranes to 800 tons and rough terrain cranes to 80 tons, our crane service branches have the variety and inventory of heavy lift cranes to fit your needs.

Eliminate Delays

One of the benefits of Barnhart's coast-to-coast network is our deep knowledge of state and federal regulations in all 50 states. Our specialists have the resources and personal contacts to help you navigate the varying DOT rules, regulations and permitting processes across the U.S.

Engineered For Success

Moving large equipment through an operating plant takes more than just the right trailer. Engineering is required to account for everything from ground bearing issues to load configuration. With Barnhart's specialized team of more than 50 engineers, we have you covered.

Lower Mobilization Costs

Our branch network allows us to station cranes across the U.S. This decentralized approached could lead to significant reductions in the cost to mobilize a large crane for your project.
