The proposed action decontaminates six experiment loop piping systems and the canal recycle system of the Advanced Test Reactor, TRA-670. The loop piping becomes radioactive during normal operations and needs routine decontamination to reduce worker exposure for equipment maintenance and to support programmatic requirements. The proposed action uses an outside vendor to complete decontamination. The basic scope of this work entails attaching a recirculation pump, chemical mixing and surge tank, piping, and resin column to six Advanced Test Reactor experiment loops (1D-N, 1C-W, 2A-C, 2B-SE, 2D-SW, and 2E-NW). Each loop is made of stainless steel or inconel piping and includes pumps, piping, heaters and valves.
