Nuclear Plant Power Increase - Efficient Removal and Replacement of Equipment

Projects & Case Studies· Remove and Replace ·Nuclear

0 Views

At a Mississippi nuclear station, Barnhart played a critical role in a major plant uprate project — managing the lift, transport, and handling of over 19 million pounds of equipment to support a power increase.

Key components replaced included:

Main transformers

Feedwater heaters

Reactor feed pumps

Generator and turbine components

All retired equipment was safely relocated to an on-site mausoleum storage facility.

To meet the demanding schedule, Barnhart ran parallel operations with 150+ crew members and coordinated over 300 trucks for mobilization. A dedicated logistics team managed field crews and subcontractors, while custom tools were fabricated and delivered as needed.

Despite the scale and complexity, Barnhart improved timelines across every scope — a result of outstanding planning, engineering, and execution in the field.
