An equipment set designed to be remotely installed into the 324 Building Radiochemical Engineering Complex (REC) to remove debris, flooring, and soil from B-Cell. These arms operate in a typical excavator fashion, but are mounted to a steel post mounted to the side of the cell wall. The REAs are custom equipment that are designed for the 324 Facility, and are intended to make remote mounting and hose connection possible with support from the gallery.
