The contract, valued at nearly $465,000, is the second Waste Treatment Plant contract awarded to CEC. The work will be performed from June 2004 through January 2007 with subcontractor Thompson Mechanical.
In announcing the award, Martin Talbot, CEC President, said, "We look forward to complementing Bechtel's excellent work at Hanford by providing equipment design and fabrication services based on proven technology."
The Extraction Equipment System will remove through wall devices or TWDs (camera or light assemblies, decontamination plugs, shielded windows, among other items) that penetrate the shielded concrete walls of the Waste Treatment Plant's high-level waste, low-activity waste, pre-treatment and laboratory facilities.
The system will operate from the non-contaminated or "cold" side of the wall and will work by sliding the TWD to be repaired out through a double polyethylene containment bag, which is especially designed to prevent the spread of any potential contamination.
Once the TWD is in working order, it can be inserted back into the wall using the reverse process.
