Feedwater Heater Removal and Replacement

Barnhart was contacted to remove and replace 94,000-pound stage one low-pressure feedwater heaters (FWH) at a nuclear power plant in Arizona as part of a multiyear project that involved 12 FWHs. A 500-ton slide system was set up to move the heaters.

The crew brought in 30K sliding gantries in order to position the heater for an awaiting crane.

Wall panels on the turbine building were removed to access the heater. The team set up a 600-ton crane and used its Quad Block to maneuver the heater out of the building.

The heater was loaded to a 6-line PSTe and moved to a staging area on site. The process was reversed for the heater replacement.
